2 TeleOximetry PC Access Software Requirements The Datex-Ohmeda TeleOximetry PC Access software lets you access trend data stored on a 3900/3900P pulse oximeter and transfer the data to a PC. Each data transfer creates a file you can view or use to generate reports, including SpO 2 InstaReports and Relative Perfusion Index (PIr ) pulsatile value InstaReports. The interface (menus, messages, etc.) is in English. This manual contains: Software and hardware requirements, installation instructions, and setup information. Instructions for starting the program and using each of three methods to receive data from the 3900/3900P on your PC. Instructions for editing trend data files and creating an InstaReport. How to view, clear, and close the session log. Status messages, error messages, and troubleshooting information. Microsoft Windows 95, 98, 2000, XP, or Windows NT 4.0 Intel Pentium 90 MHz processor (minimum) 32 MB RAM and at least 4 MB free disk space on the hard drive Data modem (internal or external) installed on the PC and 56K external data modem connected to the 3900 or 3900P (modems are not needed for the Direct Access feature) 3900/3900P system software version 4.0 or greater. Important: For complete access to the TeleOximetry PC Access features, the 3900/3900P system software must be version 4.0 or above. If your system software is below version 4.0, the PC program will download all stored trend data to the PC and save the data in a single file. You will be unable to create an InstaReport summary. An upgrade to version 4.0 or above is strongly recommended. These instructions assume 3900/3900P system software version 4.0 or greater is installed. 2

3 Installation 1. Power on the PC and insert the TeleOximetry CD into the CD drive. 2. When the Start-up screen is displayed, choose from the following options: Install Software installs the software on your PC. View Manual opens these instructions (read or print them).

May occur when using a laptop PC with a PMCIA modem. COM port selected at Direct Access screen is in use by another device. An error occurred while opening, closing, reading from, or writing to a file. The file is not in the correct format because it originated from an oximeter with system software prior to version 4.0. The low SpO 2 alarm limit you entered was not in the acceptable range. A modem driver and modem were detected, but the program cannot connect to the phone line. The SessionLog.txt file located in the TeleOximetry directory is too large. There is no trend data stored in the 3900/3900P. The modem did not detect a dial tone or the line is busy. Connect modem to a phone line. Connect the 3900/3900P to an open COM port or disable other devices using the COM port you selected. Verify that the file is not read-only and the amount of disk space is adequate. If this error occurred while downloading, data may have been lost. Repeat the download. You can open and view the file. You can copy and paste the data into another application. Record tabs and the InstaReport menu are not available. When you select InstaReport SpO2 Limit, enter a number from 0 (zero) to 100.
