Speech Encryption
You can enable/disable speech encryption for the current channel, so that speech is sent after encryption.
5.5.TOT (Time-Out-Timer)
This function is to prevent overlong channel occupation. If the radio keeps transmitting signals for a duration
longer than the one set by a dealer through programming, the radio will stop transmitting and warning tone
will ring. To stop the tone, release the PTT key. You can transmit again after a period (set by a dealer) by
holding down the PTT key.
If early warning is enabled, you will receive an early warning of transmission halt when time is nearly out.
5.6.Emergency Alarm
Under emergency, you can send an emergency alarm by pressing the side key programmed as the
Emergency Alarm key. Please specify acousto-optic effect by setting an alarm type and the content to send
to other radios in the group by setting an alarm mode.
You can have these settings done by a local dealer through programming. To quit emergency alarm, press
the side key programmed as the Quit Emergency Alarm key.
Alarm Types
1) Siren Only —— After the radio enters the emergency state, the siren only sounds locally and the control
center will not receive any alarm signal.
2) Regular —— The radio sends emergency alarm and audio-video alert.
3) Silent —— The radio sends emergency alarm but no audio-video alert. When the radio receives speech
signals, the speaker will not be turned on until the PTT button is pressed.
4) Silent with voice —— The radio sends emergency alarm without audio-video alert. When the radio
receives speech signals, there will be no audio-video alert until the PTT button is pressed.
Alarm Modes
1) Alarm: The radio sends an emergency alarm and then quits alarm mode.
2) Alarm with call: The radio sends an emergency alarm can initiates an emergency call by holding down
the PTT key.
3) Alarm with voice to follow: The radio sends an emergency alarm and then sends background tone
periodically.
Note:
An emergency alarm is non-speech signals sent from a radio in a group to other radios in the group, so
that alarm prompt will be given off on these radios.
To guarantee communication under emergency, an alarm call has a higher call priority than a common call
does.
