4.26 FAILSOFT (P25 TRUNKED)
When the site-link to the VNIC is down, the site is operating in Failsoft mode. Radios operating on that
site can still communicate with each other, but not with the rest of the system. The radio provides a visual
indicator ( icon) on the display and plays a tone for a configured interval to indicate that the site is in
Failsoft. This tone interval range is 0 to 120 seconds. This tone is not played during incoming voice or PTT.
4.27 EMERGENCY OPERATION
The radio can be programmed to enable emergency mode. Unit name displays on dispatcher console if an
emergency signal is received from another radio on a digital channel.
4.27.1 Declaring an Emergency Call
To declare an emergency:
1. Press and hold the emergency button on the control head. The length of time you need to hold the button
is configured using RPM2.
2. The emergency is indicated on main display as shown below:
• For digital channels, the radio transmits the talkgroup or radio ID to the dispatch console and
receiving radio.
• The radio can be programmed to have a dedicated emergency channel, which can be activated from
analog or digital channels.
• The radio can also be programmed to send an Emergency Alarm in addition to or in place of the
emergency call (P25 modes).
The radio goes through transmit and receive cycles if so configured. Speak into the microphone while
the radio is transmitting or press PTT to talk.
3. To exit emergency, power cycle the radio or select EXIT EMERGENCY from the CALL menu.
If enabled via programming, you can clear an emergency by pressing the button programmed for the
Monitor/Clear function and then the emergency button.
