the rushing sound stops.
3. To turn off the scanner, turn VOL counterclockwise to OFF.
Notes:
. The scanner will not enter scan mode if there are no frequencies stored in channels, or if all channels are
locked out in the channel storage bank(s) that you are attempting to scan. In either of these cases, the
scanner will display All channels Locked out! See “Programming Your Scanner” on Page XX.
. If SQ is adjusted so you always hear a rushing sound, the scanner will not scan properly. Rotate the
squelch control until the rushing sound stops.
. If SQ is adjusted precisely at the threshold where the rushing sound stops, the radio will be most sensitive
to very weak signals. The radio may also receive unwanted noise or signals that are too weak to
understand. Most users prefer to position the squelch control a little bit past the point of threshold to avoid
receiving noise or signals that are too weak to understand.
Scanning
To begin scanning channels or to start scanning again after monitoring a specific channel, press SCAN.
Notes:
. You must store frequencies into channels before the scanner can scan them. The scanner does not scan
through empty channels.
. To change the scanning direction, press ^ or v while scanning.
The scanner scans through all channels (except those you have locked out) in the active channel storage
banks (see “Turning Channel Storage Banks Off and On” on Page XX and “Locking Out Channels or
Frequencies” on Page XX).
Turning Channel Storage Banks Off and On
To turn off channel storage banks while scanning, press the bank's number key so the bank's number
disappears. For example, to turn off bank 1, press 1. The scanner does not scan any of the channels within
the banks you turned off.
To turn on channel storage banks while scanning, press the number key until the bank’s number appears.
For example to turn bank 1 on again, press 1.
You cannot turn off all channel storage banks. There must be at least one active channel storage bank.
You can manually select any channel in a channel storage bank, even if the bank is turned off.
