OPERATION

TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH

Note: Make sure the scanner’s anten- na is connected before you turn it on.

1. Turn SQ fully clockwise.

2.Turn OFF/VOLUME clockwise until it clicks and you hear a hissing sound.

3.Turn SQ counterclockwise until the hissing sound stops.

Notes:

If the scanner picks up unwanted, partial, or very weak transmis- sions, turn SQ counterclockwise to decrease the scanner’s sensitivity to these signals. If you want to lis- ten to a weak or distant station, turn SQ clockwise.

If SQ is adjusted so you always hear a hissing sound, the scanner does not scan properly.

OFF/VOLUME adjusts both the broadcast volume and the volume

of the beep you hear when you press the scanner’s keys.

USING SERVICE

SEARCH

To scan a service search bank, press any of these buttons:

POLICE

FIRE/EMG

AIR

MARINE

To scan the PRIVATE bank, press

PRIVATE.

Note: You cannot scan the PRIVATE bank until you have stored frequen- cies in it. See “Storing Frequencies into Channels” on Page 21.

The scanner scans through all non- locked channels (see “Locking Out Channels and Frequencies” on Page 23) in the bank you selected, SCAN scrolls, and the bank’s name appears at the top of the display.

The scanner scans the channels with- in the bank from the lowest to the highest channel number. If the scan- ner detects a broadcast, it stops on the channel. When the broadcast ends, the scanner continues to scan higher channels in the bank. When the scanner finishes scanning all chan- nels in the bank, it returns to the low- est channel in the bank and starts scanning again.
