5. COMMON FUNCTIONS AND FACILITIES
5.1 SWITCH-ON/SWITCH-OFF
• Momentarily press the On/Off/Volume Knob to switch the radio ON.
• The display will illuminate and show a ‘Welcome
Message’ and the Trunk Identity of the radio.
• After a brief time the display will revert to the Phonebook Screen,
at which time the radio is ready for use.
• Pressing and holding the On/Off knob for approximately 2s will switch the radio Off.
• On non tracking radios, the radio will automatically turn Off
after several hours of inactivity (i.e. no buttons pressed). The radio will emit
warning beeps for 10 seconds prior to switching off. Pressing any button will
reset this timer.
The radio can also be setup to switch on automatically with the Vehicle Ignition whenever the vehicle is started.
5.1.1 In-Service Indication
After switch on the radio must ‘Register’ with the Trunking Network before
it can place or receive calls. When the radio is searching for the best
channel a rotating arrow and the signal strength of the scanned channel is
displayed. When the radio has registered, the rotating arrow symbol will
disappear. The radio is said to be IN SERVICE when it is in contact with the
Network, and the arrow symbol is not displayed. A call cannot be made until the radio is IN SERVICE. The radio can queue
one call (identified by the * icon) which will be made as soon as the radio gains service.
5.1.2 Volume Adjustment
The Volume Control adjusts the speech level at the loudspeaker. Rotating the knob clockwise increases the volume and
anti-clockwise decreases the volume.
Note: The radio can be programmed so that the volume cannot be turned off completely.
