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.
