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.
