Adjustment tips and functions

The squelch should only be switched off for servicing purposes. With the squelch threshold

this position for 3 seconds.

왘 Turn the jog dial to the right to switch the squelch on.

Scanning for, releasing and selecting frequency presets

If you call up the “Scan New List” menu item, your receiver scans for unused frequency presets.
