Chapter 2: Services and Features
1 Internal Communication Talkgroups – regular talkgroups for the entire campus and
individual buildings to communicate between staff members.
2 Internal Alarm Talkgroups – emergency talkgroups, individual for each building.
3 External Alarm Talkgroup – an emergency talkgroup to alert the entire campus.
The staff in individual buildings uses the dedicated Internal Communication Talkgroups for
daily routines and the Internal Alarm Talkgroup for safety procedures. The campus staff in
every building also scans the External Alarm Talkgroup.
The campus IT administrator assigned in Customer Programming Software (CPS) the Timed
Talkgroup Change function to a One-Touch Button to switch between the original Internal
Communication Talkgroup, and the Internal Alarm Talkgroup. This way the radio users can
immediately switch to the emergency talkgroup and start an internal emergency call.
One of the staff members in building A is in an emergency situation. The person presses the
One-Touch Button to switch to the Internal Alarm Talkgroup and starts the emergency call. The
other staff members in building A hear the voice communication on the Internal Alarm
Talkgroup. It turns out that the emergency is serious and one of the building administrators
starts the global alarm for all campus buildings.

Broadcast Call

Broadcast Call enables the dispatcher to transmit to all radios in the specific area. This call is only
available on GMOI network.
The radio joins calls received with a communication type broadcast and displays a notification that this
call is a broadcast call. Typically, this call type is addressed to the broadcast address (ISSI).
A broadcast call takes precedence over any other call that has the same or lower call priority.

PTT Double Push

The PTT double push (D-PTT) feature enables the radio to generate a specific tone sent to other
radios in the talkgroup. You can send the tone by pressing PTT twice, or pressing the preconfigured
One-Touch Button once.
After the D-PTT tone is played, you can press and hold the PTT once again to get the permission to
talk. Otherwise if you press the PTT while the D-PTT tone is played, it is ignored. D-PTT tone is not
audible on sending radio.
To send the tone, you press the PTT twice in a period defined in Customer Programming Software
(CPS). The D-PTT is triggered only when the radio is in idle or group call mode. The D-PTT tone is not
played on the sending radio.
If the PTT is kept pressed after second press and the radio finishes sending the D-PTT tone it allows
starting group call. You are notified of the behavior by the permission to talk tone after D-PTT tone
ends. If PTT is released after the second press, only the D-PTT tone is sent.
NOTICE: The D-PTT tone is sent as voice, hence the receiving radio plays the sound no matter
whether the feature is enabled on it.
You can adjust the D-PTT tone volume level in the speaker or earpiece of the sourcing radio. Disabling
all the tones does not affect the sent tone volume. From the MMI, you can change the D-PTT tone to
be single, double, or triple. The tone type can also be changed in the codeplug.
