seconds.

Automatic standby feature

Your PMR unit is fitted with special circuitry designed to
extend the life of your battery. If the radio is not used for four
seconds, it will automatically go into the standby mode. This

If a signal is detected, it will automatically return to full power.

microphone and loudspeaker*, which are usually sold together.
The jacks are located under the protective cover on the top of
the unit.
To connect an external loudspeaker/microphone headset:
