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.
