When your radio receives an Emergency Alarm, it displays the
Emergency Alarm received indications until acknowledgement
is sent (if enabled) and you exit the Emergency mode, by long
pressing the emergency button.
You will not be able to receive any other indications or displays
for any other calls until you exit the Alarm List.
When your radio receives an Emergency Alarm, and you
change the radio channel, the radio automatically exits the
Alarm list. However, the radio remains in Emergency mode so
the new channel displays the Emergency icon and the LED
blinks red. When you change the radio channel back to the
previous channel, radio continues to display the Emergency
icon and the LED continues blinking red.

initiating radio responds, the LED blinks green, the radio

speaker. You see the Group Call icon, the group ID, and
