Your radio may be programmed with options that affect
the way it behaves when it receives a call from another radio.
Receiving signal
While the radio is not receiving signals, it will remain in standby 
mode to conserve battery power. When a signal is received 
under normal conditions, the LED indicator on the upper edge 
of the radio will light Green and the icon will appear on the 
display. Adjust the volume control for a comfortable listening 
level. Once no further signals are received, the unit will return to 
standby mod
