Scanning the channel bank for free channels –

SCAN

Before putting one or several transmission links into operation,

you should scan the channel bank for free channels.

Starting the scan and storing the scan result

 Before starting the scan, switch all transmitters of your

system off, since channels used by switched-on

transmitters will not be displayed as “free channels”.

 Select the “SCAN” menu.

 Select “START” and confirm your selection by pressing the

SET button. After the scan is completed, the number of free

channels is displayed. Pressing the SET button once more

will store the scan result and lock all channels that are used

or subject to interference.

Releasing locked channels

 Select the “SCAN” menu.

 Select “CLEAR” and confirm your selection by pressing the

SET button. All channels can now be selected again.

Adjusting the squelch threshold – SQELCH

The receiver is equipped with a squelch that can be adjusted via

the “SQELCH” menu (

see “Squelch” on page 34). The squelch

eliminates annoying noise when the transmitter is switched

off. It also suppresses sudden noise when there is no longer

sufficient transmitter power received by the receiver.
