Auto Squelch Feature
The radio is equipped with an automatic squelch system, which shuts off
weak transmissions and unwanted noise due to terrain conditions or if you
have reached your range limit.
Automatic Power Save Feature
Your radio has a unique circuit designed to dramatically extend the life of
the batteries. If there is no transmission within 5 seconds, your radio
switches to the Power Save mode. The radio is still able to receive
transmissions in this mode.
