Operating the Radio in Scan Mode
In this mode the radio scans a number of pre-defined channel frequencies searching for
a busy one. When a busy channel is found, the radio provides reception on that
channel. The Scan facility must be programmed into the radio before it can be selected,
or used.
Note …
A channel is defined as busy when it is receiving a signal strong enough to
override the squelch setting.
What happens after a busy channel is found depends on how the radio is programmed.
There are two possible options: Hold and Pause.
q
If Hold is programmed, the radio remains tuned to the busy channel until the
CHs button is pressed to resume scanning.
q
If pause is programmed, the radio remains tuned to the busy channel for six
seconds, then automatically resumes scanning (even though the channel
remains busy). If during the six seconds the radio is keyed, or the CHs button is
pressed, the radio remains tuned to the busy channel; scanning does not
resume until the CHs button is pressed again.
The radio can be programmed with up to 15 scan groups, each containing up to 15
channel frequencies. Squelch is automatically switched on when scan mode is
selected. Display blanking does not operate in scan mode.
Selecting Scan Mode
To select Scan mode, press the SCN button. Check that the display shows Scn and a
number between 1 and 15; the number corresponds to the currently selected scan
group.
Selecting a Scan Group
When in Scan mode, the required scan group (a number between 1 and 15) is selected
by pressing the SELs or SELt button.
Transmitting and Receiving
To transmit when the scan function is on hold, or pause, key the transmitter by pressing
the fist microphone's PTT button. Check that the radio's Tx indicator lights, and then
speak clearly into the microphone.
Reception is heard through the loudspeaker. The volume is adjusted using the VOLs
and VOLt buttons. When a signal is received, the radio's busy indicator lights. If the
squelch facility requires adjusting, refer to ‘To Adjust the Squelch Level’ on page 30.
The squelch cannot be switched off in scan mode.
