Nova Talk on iphones and ipads The Nova Talk user interface is designed as a tabbed structure for the screens "Contacts," "Groups," "Messages," "Map" and Recent Calls. Within each Tab, there are context sensitive menus which are invoked by pressing the blue information circle on items within the tab. Samples of the main tabs and other common screens are shown below. Contacts Tab Groups Tab Messages Tab Map Tab ipad Contacts/Map Screen 6

Contact and Group Presence Icons Presence is supported for individual contacts and groups. These presence icons are updated during each presence update, or every 10-12 minutes. You can force a presence update on the device by swiping down on the screen. Contact Presence Contact is Available Contact is Unavailable Contact is in an Nova Talk call Contact is in DnD (Do not disturb) mode Contact not responding; this circle will turn to grey with the next presence update Contact is signed out of Nova Talk Contact is blocked Group Presence Group is active in call Group is available Group is blocked 7

Group Types and Maximum List Sizes Nova Talk supports a total of 1024 total entries per user. This is the total combination of Contacts, Groups and Group members allowed in the lists. Personal Groups (Group Size Limit is 255): Personal Groups are created by a user on their device and are only visible on their own Group List. Only the creator may initiate calls to this group. Member Groups (Group Size Limit is 255): Member Groups are also created on a device and are visible in all members group lists. Any member of the group may initiate a call. Enterprise Open Groups (Group Size Limit is 255): Enterprise Open groups are created in the portal and are available for any user in the enterprise to search out and join. Enterprise Closed Groups (Group Size Limit is 255): Enterprise Closed Groups are created in the portal and are not searchable. Enterprise Dispatch Groups (Group Size Limit is 255): A dispatch group is created in the administrative portal and is customizable according to who can receive or generate calls. This is useful, for example, for a company with a facilities department who might need to receive calls from a large number of people who want to be able to call facilities but don t want to be included on every communication from this group. Surveillance Group (Group Size Limit is 255): This type of group mimics an LMR radio, with a dedicated channel that users can join or leave over time. Once begun, the call will stay open for a configurable amount of time up to two hours. Broadcast Groups (Group Size Limit is 60,000) Broadcast groups are used to deliver high priority, pre-recorded voice bursts that are a one-way announcement. This kind of group is set up by Nova Talk Support. Users can be placed into a Broadcast group with the privilege to generate or receive announcements (or both). This type of announcement will interrupt any ongoing calls at the time of broadcast. Data Usage Nova Talk is a VoIP application that requires a Data Plan. Data usage is dependent on the device type and network service type (2G, 3G, 4G). Regardless of device and network type, while idle and not making any calls, Nova Talk usage is approximately 2MB/month. Per hour usage: 4G network: 18 MB/hour 3G network: 8 MB/hour Ten hours of talk time average: 4G network: 180 MB/month 3G network: 80 MB/month 8

Once the client settings are adjusted for this, the Emergency call capability will be reflected on the screen by a red tab. An emergency call will send an insistent visual flashing signal and pull recipients into the call until they acknowledge it.

While users are On Duty, location information is available, and while Off Duty, location information is not available. While Off Duty, users are still available for Nova Talk Calls. If a user responds to an Nova Talk call, or starts an Nova Talk call, they will be placed into On Duty mode. This option is generally used when the Nova Talk users have personal devices. 17

Talker Override/Preemption The talker priority feature is available when it is set for each user in the Admin Portal. When configuring a user or group via the Administrative Portal, you may assign priority from levels 1-5 (default level is 0). Higher priority users may interrupt a lower priority ongoing call. While in call, when a priority user presses the PTT button to talk during a time when a non-priority user has the floor, the non-priority user s talking privilege will be revoked and the floor granted to the priority user. Priority users are treated on a first come, first served basis when multiple priority users of similar levels request the floor. A user who is assigned talker override in a specific group also has the privilege to take over the floor of an ongoing group call, regardless of the priority levels of the people in that same call. Priority settings, for users or groups, are not reflected on the devices. A Broadcast group and configured Emergency group support a preemption feature. Whenever a Broadcast call is made, it will preempt every other call in which the members of the broadcast group are currently participating. Once the user has heard the broadcast message, he/she can make other Nova Talk calls again. In the case of an Emergency group call, the call will pull all members of the group into the call, and those users must acknowledge the call. The caller must take the call out of the emergency state in order for it to end. Call Override Based on User and Group Priority Every Nova Talk User has an assigned Priority Level between 1 (lowest) and 5 (highest). Nova Talk supports call override on 1:1, Ad hoc and Group Calls. Call Override on 1:1 and Ad hoc PTT Calls Ad hoc and 1:1 PTT calls can be overridden by a User or a Group with a higher priority than the members of the 1:1 Call. Call Override on Group Calls Members of an ongoing Group Call can be taken out of the Group Call and put into a new 1:1 or Ad hoc call if the Calling Party has a Priority higher than the Group Call. In this case, the Group Call will continue with the remaining members. Call Override on Group Calls (by calling Group) Members of an ongoing Group Call can be taken out of the Group Call and put into a new Group Call if the New Group has a Priority higher than the ongoing Group Call. In this case, the ongoing Group Call will continue with the remaining members. 28
