5. COMMON FUNCTIONS AND FACILITIES
5.1 SWITCH-ON/SWITCH-OFF
Turn the On/Off/Volume knob clockwise to switch the
portable radio
On.
The display will illuminate and show a ‘Welcome Message’
and the Selcall Identity of the radio.
After a brief time the display will revert to the Idle Screen,
at which time the radio is ready for use.
Turning the
On/Off/Volume knob anti-clockwise will switch the portable radio Off.
If the radio
Power Down Timer is enabled, the radio will automatically turn Off after a
predefined duration of inactivity as set by the FPP (i.e. no keys pressed). The radio will emit
warning beeps for 10 seconds prior to switching off. Pressing any key will reset this timer.
5.1.1 Volume Adjustment
The top On/Off/Volume knob adjusts the speech level at the loudspeaker or remote speaker
microphone. Rotating clockwise increases the volume and anti-clockwise decreases the volume.

Channel Change control.
