Battery meter
The battery meter is located in the bottom left corner of the
LC display on the unit. The symbol looks like a battery with
vertical hatching. As the power is used, the bar will disappear.
Low battery indicator
When the batteries need to be changed, the hatching will
disappear. To ensure uninterrupted communication, replace
the batteries as soon as possible.
Note
Always use alkaline batteries for replacements. If you do not intend to use the radio for any
length of time, remove the batteries. Batteries may corrode and leak when left unused for
prolonged periods and permanently damage your radio.
Do not put batteries into a fire or expose them to high heat. They may explode!
4. Operation
Switching on your PMR radio
To switch the radio on or off, press and hold the power
button for at least 2 seconds. The unit will bleep, the LCD
panel will display information about your radio and the panel
will be illuminated by a green light for several seconds.
Communication
You can communicate in two directions with your new PMR
radio. Eight channels are available. You can either talk directly
to others and hear their response or call them with an audible
tone.
PMR radios can only communicate when either the TALK
button (for speech) or the CALL button (for paging) is
pressed. The unit can only receive when both buttons are
fully released.
Receiving communications
When your radio is switched on and is not being used to
transmit voice communication or for paging, it will always be in
the receiving mode.
You cannot receive any transmissions when the TALK or
CALL button is pressed, even if you are not speaking.
Pressing these buttons automatically switches off the
receiving mode.
If you are using the unit for conversational purposes, you must
release the TALK and/or CALL button to be able to hear the
responses of the other person.
