22 Basic operation
Turning the radio on and off
Give a long press of the on/off key to turn the radio either on
or off.
When the radio is first turned on, the red, green and amber
LEDs flash briefly and the radio gives two short beeps.
Unlocking your radio
You may need to enter a personal identification number (PIN)
before you can use your radio. If the display shows either —
or — — after power-up, enter your assigned PIN.
Once you have entered your PIN correctly, the radio sounds
two short beeps and normal operation is now possible.
If you do not know your PIN or if your radio gives a long, low-
pitched beep, consult your radio provider or administrator.
Adjusting the speaker volume
Note: The volume control also changes the volume level of the
radio’s audible indicators.
Rotate the volume control clockwise to increase the speaker
volume and counterclockwise to decrease the volume.
Selecting a channel or group
Use the channel selection keys or to scroll
through the channel list until the channel or group you want
is appears in the display.
A group can be either a voting group (see “Using the radio in
different repeater areas” on page 31 ) or a scan group
( “Scanning a group of channels” on page 32 ).
