OPERATION

Before you start using your CB, you should know how to use it effectively and courteously. “CB Operation Tips” on Page 15 contains information that will help you get more enjoyment from using your CB.

TURNING ON THE CB AND RECEIVING TRANSMISSIONS

1.Turn SQUELCH fully counterclock- wise.

2.Set CH-9/NOR/CH-19 to NOR, S/RF/ SWR/CAL to S/RF (send and receive), and CB/WX/PA to CB.

3.To turn on the CB, turn OFF/VOLUME clockwise until it clicks and you hear a hissing sound. TX/RX lights, the CB displays the last-tuned channel number, and the SWR/RF/Signal Meter lights.

4.Turn SQUELCH clockwise until the hissing sound stops.

Note: If the CB picks up unwanted, partial or very weak transmissions, continue to turn SQUELCH clockwise to decrease the CB's sensitivity to these signals. Turn SQUELCH coun- terclockwise if you want to listen to a weak or distant station.

5.Adjust OFF/VOLUME to a comfort- able listening level.

6.To manually tune channels, turn the tuning control beneath the display to select a channel. The selected channel number appears, and the SWR/RF/Signal Meter shows the signal strength.

To quickly tune to Channel 9 or 19, set CH-9/NOR/CH-19 to CH-9 or CH- 19. 9 or 19 flashes.

Important: Always give emergency communications priority on Chan- nels 9 and 19. Your CB provides for fast selection of Channel 9 and 19 for that reason.

Notes:

•Selecting either Channel 9 or 19 overrides the manual channel selection control.

•All channels, with the exception of Channels 9 and 19, by agree- ment, are available for general communications. Channels 9 and 19 are reserved for motorist assistance and for reporting emergency situations, hazardous road conditions, and the like.

7.If necessary, turn RF GAIN clockwise to boost the strength of a signal.

8.If you hear low-level popping-type noise, set NB/OFF to NB to turn on the noise blanking circuit.

9.To improve communication quality, set ACE/OFF to ACE. This enables the ACE circuit.

10.To turn off the TRC-446, turn OFF/ VOLUME counterclockwise until you hear it click.
