CHANNELS

1.Turn SQUELCH and VOLUME fully counterclockwise.

2.Turn VOLUME back clockwise until you hear a hissing sound.

3.Turn SQUELCH clockwise, then leave it set to a point just after the hissing sound stops.

Notes:

If the scanner will not scan, turn SQUELCH further clockwise.

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

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

Good references for active frequen- cies are the RadioShack “Police Call Guide including Fire and Emergency Services,” “Official Aeronautical Fre- quency Directory,” and “Maritime Fre- quency Directory.” We update these directories every year, so be sure to get a current copy.

Note: To store trunking system fre- quencies, see “Programming Trunked Frequencies” on Page 26.

Follow these steps to store frequen- cies into channels.

1.Press MANUAL, enter the chan- nel number (1–300) where you want to store a frequency, then press MANUAL again. The chan- nel number appears.

2.Use the number keys and to enter the frequency (including the decimal point) you want to store.
