•  Upon successful emergency declaration: 

¾ 

An emergency tone will sound in the radio’s speaker/headset if the radio is not in stealth mode. 

¾ 

At the declaring radio, the Emergency button flashes red if the radio is not in stealth mode. The 
administrator can configure the radio to automatically transmit upon successful emergency 
declaration, at which point the MENU button will flash red. However, the MENU button flashing 
red is not a requirement for successful emergency declaration. 

¾ 

On the declaring radio during an emergency call declaration, the talk group that the emergency is 
declared on is temporarily displayed and then the word “EMERGENCY” flashes on the second 
line of the display.  

¾ 

For an emergency alert declaration, “EMERG ALERT” appears in the bottom line of the display. 

¾ 

For an emergency call declaration, other radio users and/or dispatchers at consoles will hear the 
emergency signal, a distinctive 3-tone burst. They will also hear audio from the declaring radio’s 
“hot” microphone, if any. 

¾ 

For an emergency alert declaration, only dispatchers at consoles will hear the emergency signal 
and, if any, audio from the declaring radio’s “hot” microphone. 

¾ 

For an emergency call, the declaring radio’s microphone remains “hot” for a predetermined 
amount of time. In other words, the radio transmits audio for a period of time even when the 
microphone’s PTT button is not pressed. Audio is transmitted over the emergency talk group. 
When the microphone is “hot” for this initial period (typically ten seconds), simply speak into it 
for voice transmission. 

If an emergency declaration is not successful, the radio will periodically re-attempt until it is successful. 
During this retry period, the radio will flash “EMERG PEND” on the bottom line of the display. It will 
display “EMERG RETRY” for each attempt. 

When this feature is enabled and an emergency call or alert is declared by pressing the emergency button, 
the radio will not play a tone and will display an abbreviated emergency message (default is EBA). This 
feature is enabled or disabled via programming or via the menu. 

 

If the Silent Emergency feature is enabled or disabled via programming, the setting will 
survive power cycle. Enable/Disable selection via the menu will NOT survive power cycle 
and the enable/disable state will revert to the programmed setting at power up. 

 

Check with the system administrator to ensure that the radio is programmed to allow an 
emergency to be cleared. 

If enabled via programming, clear an emergency by: 

1.  Pressing and holding the CLR/CLEAR button and simultaneously pressing the emergency button. 

2.  After the Emergency Cleared Tone sounds, release both buttons.
