ZOLL Document Number: 90A0001 Page 7 of 25 1. INTRODUCTION This document establishes the procedures and controls for the creation, review, approval, distribution, retrieval and archival of ZOLL Manufacturing Corporation (ZOLL) documents required by FDA s Quality System Regulation and ISO 13485 Quality Systems. These controls ensure that documents are reviewed for adequacy and approved prior to issuance; are available at all location for which they are designated, used, or otherwise necessary; and all obsolete documents are promptly removed from all points of use or otherwise prevented from unintended use. 2. SCOPE This procedure applies to documents required by 21 CFR Part 820.40 and ISO 13485:2012 clause 4.2. Quality records (records maintained to demonstrate the conformance to specified requirements and the effective operation of the quality system) are outside the scope of this procedure (see 90E0004 Maintenance of Quality Records). 3.

ZOLL Document Number: 90A0001 Page 8 of 25 4. CONTROL NUMBER RESPONSIBILITIES 4.1 Documentation Control assigns control numbers to all Type 20, 90 and 95 documents, labels, labeling, advertising, and promotions. 4.2 Design Engineering assigns control numbers to all documents and drawings for assemblies, fabrications, test fixtures and tools, purchased P/Ms, and pertinent documentation sheets (10-19, 21 & 80). 4.3 Software Engineering assigns control numbers for all device software, programmed components and software documentation (91, 92, 93, 94). 4.4 Hardware Engineering assigns control numbers for hardware documentation not including component specifications, drawings, requirements, and procedures. These include documents such as hardware release notes and reference documents (96). 4.5 Refer to the latest revision of ZOLL 90A0026 for a description of the ZOLL numbering system. 4.6 If a question arises as to what should be the Type, Class, Root Number, or Extension for a particular P/M, Quality Assurance will resolve the issue. 5. DOCUMENTATION CONTROL Documentation Control is responsible for maintaining all controlled electronic files and documents. Its responsibilities include: 5.1 Creating tracking numbers for Change Requests and Change Orders. (Details in ZOLL 90A0023.) 5.2 Maintaining Change Request and Change Order logs. 5.3 Issuing approved, new, or revised documentation. 5.4 Maintaining file storage of the originals of approved documents/drawings in a secured area with limited access. This includes both on-site and off-site storage of documents. 5.5 Maintaining electronic files of documents, when available, on the ZOLL network. The documents on the network may be accessed by ZOLL employees on a read-only basis. 6. DOCUMENT TYPES 6.1 Prototype Documentation: is any document (specification, procedure, plan, protocol, report, etc.), drawing, or software that is still in the design phase. When a document is at the Prototype stage, it is not yet under Documentation Control. The process for tracking and releasing prototype documentation is explained in 90A0022.

ZOLL Document Number: 90A0001 Page 9 of 25 6.2 Controlled Documentation: Any document (specification, procedure, plan protocol, report, etc.), drawing, or software that has entered the Documentation Control System. This includes any document that requires an approved Change Order to change (i.e., a procedure), and any document that remains unchanged (i.e., an archival document). All product-related and quality system-related documents, including graphics and software, will be controlled. 6.2.1 Approved Documentation: Documents requiring approval signatures and subsequent Change Order to change or obsolete. Original documents and drawings are stored in hard-copy form in locked, limited-access files and/or electronically in a read-only directory on the ZOLL network, controlled by Documentation Control. These documents and drawings use a hard copy approval sheet 90A0001-A01 or 90A0001-A04 and revision history page 90A0001-A03. Documentation requiring the approval process include: Policies Procedures Instructions Plans Software Drawings Requirement Specifications Reference Documents Release Notes Component/Material Specifications Labeling Marketing and Advertising* *Exception: Marketing and Advertising changes that do not modify existing claims or add new claims do not require a change order to implement. 6.2.2 Archival documents require approval signatures as shown on Form 90A0001-A02. These types of documents do not undergo revision; therefore, the revision level is N/A for Not Applicable. All such documents use Form 90A0001-A02 as a front cover. These documents may also be filed electronically and/or as a hard copy. The following are examples of documents that do not undergo revision or become obsolete: Clinical study results and analyses

ZOLL Document Number: 90A0001 Page 10 of 25 Engineering Test Reports Other archival documentation 6.2.2.1 Archival Documentation: Constitutes an historical record of product-related work (i.e., Lab Notebooks), and therefore is prohibited from revision. Accordingly, the revision will be designated N/A, signifying Not Applicable. 6.2.2.2 QA Documentation: Because of its unique auditing and reporting responsibilities, Quality Assurance may establish intradepartmental documentation control for specified kinds of records, such as in-house and vendor audit reports. The nature of such documentation, as well as where they are stored/controlled is specified in the Maintenance of Quality Records SOP (90E0004). 6.3 Uncontrolled Documentation: Any document that remains outside the Documentation Control System. Uncontrolled Documentation may include, for example, certain facility related drawings, blueprints, and other non-product related drawings. 7. CREATING A CONTROLLED DOCUMENT When a new document is to be created as an approved controlled document, the author shall: 7.1 Obtain a number. 7.2 Supply the Title. 7.3 Enter the revision in the revision block on the approval page (90A0001-A01, -A02 or -A04). All new documentation begins with revision level FI (for First Issue), unless the new document is an addition to an already existing controlled document, such as a new version of a bill of materials, in which case the new document shall carry the same revision as the existing controlled document. (Example: the current bill of materials for a 10A0160-A01 Monitor Assembly is revision B. A new German version is created (10A0160-A01-GER). The new 10A0160-A01-GER bill of materials will be released at revision B.) 7.3.1 Sequential alphabetic characters indicate revision levels: the first revised version of an approved document bears the REV designator A; a second revision is indicated by REV B. A twenty-third revision is identified as REV AA. (The letters I, O, P, and Q are not to be used to indicate revision levels for released documentation.)

ZOLL Document Number: 90A0001 Page 11 of 25 7.4 Indicate on the approval page the level of review required for the document (see Review and Approval matrix in Section 8). 7.5 Create the document in an electronic file format, preferably, not handwritten. 7.6 When creating a document in an electronic format: 7.6.1 The file name format shall be as specified in section 10.2. 7.6.2 All text files should be formatted in Microsoft Word format. 7.6.3 If spreadsheets are linked to a document, they must be kept on file with that document. 7.6.4 Record the file name, size, time and date on the approval page. This information must correspond exactly to the electronic file information for the document to be accepted by Documentation Control. *Note: File size, time and date should be handwritten on the approval page after all work on the document has been completed and saved. When multiple files are linked to one approval page (such as multiple pages of a drawing) each file name, size, and time and date shall be recorded on the approval page. 7.7 Indicate on the approval page if the document affects a Device Master Record (DMR), a Device History File (DHF), is a Quality System Record (QSR), or is part of a Technical File (Tech File) required by the Medical Device Directive, as applicable. *Note: form 90A0001-A04 only requires a QSR indication. 7.7.1 If the document affects a DMR, DHF, or Tech File, the author shall indicate the overall system level (e.g. WCD, WCD 2000) and the Finished Device Level (e.g. Monitor, PBS, PPC, Garment, Electrode Belt, etc.). 7.7.2 If the document affects the DMR, the author shall then indicate if the document will require a DMR update in accordance with the Establishment and Maintenance of the Device Master Record SOP 90A0100. 7.7.3 If the document affects the Tech File, Regulatory Affairs shall determine if the document needs to be included in the Technical File file-sharing utility. Documentation Control is responsible for ensuring that the appropriate documents are added to the Technical File file-sharing utility. 7.7.4 If the document is a Quality System Record review the existing quality system Process Interaction Diagrams (see 90E0021 section 3.2) for any required changes resulting from the new or revised quality system record. Changes to an approved process interaction diagram require a change request/change order see 90A0023. 7.8 Enter the Revision History information on the Document Revision History Page (90A0001-A03). If the document is being revised, obtain the current electronic file from the Documentation Directory which will already have the previous revision

ZOLL Document Number: 90A0001 Page 12 of 25 history saved. 7.8.1 Rev will normally be FI for the first issue of a document. If the document is being changed via a change order (CO) the rev will be the next sequential revision letter. 7.8.2 CO Number: If the document is being changed via a change order (CO) enter the CO number. 7.8.3 Description of Change: If the document is being changed via a change order enter be a brief description of the change. For FI documents enter First Issue of Document. 7.8.3.1 Since changes made to 10C, 10M, and 10A drawings can be rather extensive and technical, a new document type, 96A: Hardware Release Notes, has been created to document these changes as well as explain the reasoning behind them. Therefore, the Revision History section for these document types will provide a general description of the change and a link to the corresponding 96A document, which will describe the changes in much more detail. 7.8.4 Author will be the author s initials. 7.8.5 Effective Date will be entered by Documentation Control once the document is fully approved. 7.9 Circulate the document for review and approval as defined in section 8. 7.10 Once a document has been approved by all of those designated to sign it, the author must submit the original approval page, revision history page and an electronic file and/or hard copy to Documentation Control. 7.11 An archival document must be signed by the department head of the originating department, QA, and RA upon completion. It must then be turned over to Documentation Control. 7.12 If the file is in an electronic format, Documentation Control will verify that the file name, size, time and date matches the approval page. Documentation Control will edit the electronic file of the revision history page by adding the Effective Date. This edited file will then be copied over to the ZOLL network. Documentation Control will record the new electronic file transfer information on the approval page (90A0001-A01, -A02, or -A04), then sign and date in the Documentation Control box. 7.13 All controlled documentation originals are maintained by Documentation Control in locked limited-access files or on the ZOLL network. All documents submitted in electronic format shall produce the correct document when viewed or printed. It is the responsibility of the document submitter to verify this prior to submitting the electronic file.

ZOLL Document Number: 90A0001 Page 13 of 25 8. DOCUMENT APPROVAL PROCESS When a document/drawing is to be approved for release, the author is responsible for making certain that it is distributed to the necessary reviewers for their evaluation. This may include an informal review and approval from external customers to ensure customer requirements are met. External customer review and approval will be overseen by QA/RA. The author shall indicate the required review and approval signatures by checking the appropriate boxes on the approval page of the document. Review and approval of documents in Table 1 shall be performed by the department manager (or designee) or higher level authority. Review and approval of documents in Table 2 shall be performed by the senior management (or designee) as specified. The following table defines the level of review and approval required for each type of document:

ZOLL Document Number: 90A0001 Page 16 of 25 8.1 The dated Approval signatures of those individuals indicated on the approval page for the document, are required for the document/drawing to be considered Approved Documentation and filed in Documentation Control or copied into the Documentation Control Directory. (Note: A new approval page is required for each revision - see 90A0023 SOP for Change Requests and Change Orders). 8.2 Approval requires the concurrence of all reviewers. 8.3 If changes to a draft document/drawing are made before all approval signatures have been obtained, the author must make sure that any person who signed before the changes were made be given the opportunity to review and approve the new changes. Draft copies are not required to be maintained. 8.4 If a document/drawing is withdrawn during the approval process, the author is responsible for notifying Documentation Control, which in its records will indicate that the document/drawing has been withdrawn, and accordingly update the Documentation Database. 9. DOCUMENTATION DATABASE 9.1 Documentation Control maintains a documentation database. This database may be accessed by ZOLL employees on a read-only basis via a PC connected to the ZOLL network. 9.2 The database provides a means for employees to: Search for controlled documents by title or document number. View the latest revision. Identify the size of the hardcopy document (A, B, C, D, etc.). Identify the status of the document: active (ACT) or obsolete (OBS). Identify if the document is part of a Device Master Record (DMR), and if so, which DMR. Identify if the document is a Quality System Record (QSR). Identify if the document is part of a Design History File (DHF). Identify if the document is part of the Technical File required by the Medical Device Directive. The approval date of each revision. All revisions of the document, associated Change Order numbers and approval date.

ZOLL Document Number: 90A0001 Page 17 of 25 9.3 Documentation Control will update the database when a new document or a new revision of an existing document is released. 10. DOCUMENTATION CONTROL FILE MAINTENANCE 10.1 Documentation Control maintains original copies of all controlled documentation. Documents may be kept in hard copy and/or electronic format. Documents maintained as electronic files must have a hard copy approval page in the hard copy files. All electronic files will be located in the Documentation Directory on the ZOLL network. The directory is partitioned into a Released folder and an Archive folder. The latest revision of each electronic file shall be in the Released folder. Previous revisions will be located in the Archive folder. 10.2 Electronic File Format 10.2.1 All electronic files shall be stored in the format of the software application in which they were generated (e.g.,.doc for Microsoft Word files,.xls for Microsoft Excel files,.dwg for AutoCad files, etc.). Files may also be converted to an alternate format such as Adobe Acrobat.pdf format for inclusion in a Technical File or Intranet application. When necessary, hard copy documents may be converted to electronic format for access through the Documentation Directory or inclusion in a Technical File or Intranet application. For consistency, electronic files should follow this naming convention and may use upper or lower case letters: Document number_extension_extension (if more than one) _rev (revision letter) _page#(if file pages are stored individually).extension of software application examples: CAD Drawing 10a0320_a01_ger_revb_2.dwg Word Document 90e0311_reva.doc Electronic filenames for approval pages which are not integral to the document itself, such as approval pages for Bills of Materials (BOMs), drawings, and production routings, may have a 2 character identifier added to the document number to distinguish the approval page from the document ( bm for BOMs, dg for drawings, and pr for production routings). examples: BOM cover sheet Drawing cover sheet Prod Routing cover sheet 10a0126bm_a01_revm.doc 10a0320dg_a01_ger_revb_2.doc 10a0320pr_a01_revfi.doc

ZOLL Document Number: 90A0001 Page 18 of 25 *Exceptions to the above file name format: Certain software programs, such as Protel, auto-generate lower level hierarchical file names for multi-page documents. Modifying these filenames would disable the hierarchical linking. These electronic file names need not follow the naming convention specified above. 11. DISTRIBUTING APPROVED DOCUMENTS 11.1 Only Documentation Control is permitted to make official copies of Approved Documents/Drawings. These copies are indicated by a red Documentation Control stamp. 11.1.1 Should an individual print a hard-copy of a document from the read-only Documentation Directory, this hard-copy shall be considered void and may not be used in place of an officially stamped copy. 11.1.1.1 This uncontrolled copy shall be destroyed immediately after use. 11.1.1.2 In no case shall an unstamped copy be used for manufacturing, test or inspection purposes. 11.2 Hard-Copy Distribution List 11.2.1 Documentation Control shall maintain a Hard-Copy Distribution List. This list shall indicate the individuals or locations (if any) of controlled hardcopies of the approved document. This list may be an electronic database or a paper list. This list shall be the vehicle for ensuring that new revisions are distributed to the proper locations and the old hard-copy versions are removed from service. 11.2.2 Documentation Control has the authority to add or delete entries from the Hard-Copy Distribution List. 11.2.3 Should an individual request a hard-copy of an approved document they shall be given the opportunity to be added to the distribution list. If the individual elects to not be added to the list, the document shall be stamped with an Uncontrolled Document stamp. Uncontrolled Documents will not be updated when a revision occurs. Uncontrolled Documents may not be used for manufacturing, test or inspection purposes. 11.3 Use of obsolete documents for servicing legacy products 11.3.1 At times, it may be necessary for service personnel to reference older revision documents when servicing legacy products. In the event an obsolete document is requested from Documentation Control the document will be stamped with a Not Current Revision For Reference Only Do Not Use For Production stamp. 11.4 All documents that have been revised are identified as such in the Documentation Database. The latest revision of a document is always identified in the
