5.1.14.2 Making an Emergency Call
When the emergency key is pressed and held for a time determined by the FPP, the radio
will change to emergency mode. Under emergency mode, the radio can operate in three
FPP configurable modes:
Normal: The radio will continue to respond to PTT, channel change etc. while displaying the
E icon.
Frozen: The default screen will freeze, with the E icon displayed indicating emergency
mode.
Blank: The screen will blank giving no indication to others that the radio is in emergency
mode.
When emergency mode is triggered, the radio can be configured by the FPP to transmit and
receive on a cyclic basis with FPP programmed time periods. The display will show “TX
Em”:Channel No.
During TX, the radio will generate an emergency broadcast call on either the currently
selected channel or an FPP nominated channel.
Others may listen to the automatic transmissions to hear conversations near the radio.
Turning the radio off and on will disable emergency mode.
