Setting Squelch

CAUTION:  Do not attempt to use your CB without first connecting it to an
          antenna.

1.  Turn VOLUME clockwise until it clicks to turn on the CB, then set it
    to about halfway between the minimum and maximum settings.

2.  Turn SQUELCH fully counterclockwise.  You hear background noise and
    the green BUSY LED lights.

3.  Adjust VOLUME to a comfortable setting.

4.  Turn SQUELCH clockwise just until the background noise stops.

    Note:  To receive weaker transmissions, turn SQUELCH counterclockwise.

Using Automatic Noise Limiting

If you hear low level popping noises while receiving transmissions, slide
ANL/OFF to ANL to turn on the Automatic Noise Limiting circuit. Otherwise,
leave ANL/OFF set to OFF (see "Reducing Noise" in Faxback Doc. # 46627).

Listening To Weather Broadcasts

The FCC (Federal Communications Commission) has allocated 11 channels for
use by the National Oceanographic and Atmospheric Administration (NOAA).
NOAA broadcasts your local forecast and regional weather information on
one or more of these channels in your area.

Your TRC-488 receives the following frequencies available to NOAA:

    162.400 MHz           162.500 MHz

    162.425 MHz           162.525 MHz

    162.450 MHz           162.550 MHz

    162.475 MHz

To select one of the seven available weather channels, set the mode
selector to W1-W7.  The yellow WX LED lights.

Receiving Transmissions On The Channels

After setting squelch, follow these steps to receive transmissions.

1.  Set the mode selector to CB.

2.  Follow these guidelines to select either the emergency channel or one
    of the other 39 channels:

    To select the emergency channel (Channel 9), slide CH9/OUT to CH9.
    CH9 appears on the display.



    IMPORTANT:  The emergency channel is used for reporting and monitoring
                emergency information about accidents, hazardous road
                conditions, etc.  Do not use Channel 9 for non-emergency
                messages.

    Note:  You cannot receive transmissions on Channel 9 when the mode
           selector is set to any of the W1-W7 weather channels.

    To select the other CB channels, slide CH9/OUT to OUT.  Turn CHANNEL
    to select the desired channel.  The channel number appears on the LED
    channel display.

3.  If necessary, turn RF-GAIN clockwise to increase the signal
    sensitivity.

To turn off the TRC-488, turn VOLUME counterclockwise until you hear it
click.

Transmitting

We recommend you spend some time receiving transmissions before you try to
transmit a message yourself.

Follow these steps to transmit.

1.  Set the mode selector to CB.

2.  Slide CH9/OUT to OUT.

3.  Turn CHANNEL to the desired channel.

4.  Hold the microphone 2 or 3 inches from your mouth, then press and hold
    down the microphone talk button and speak into the microphone in a
    normal voice.  The red TX indicator lights.

    Note:  Do not speak too loudly when transmitting.  It does not make
           your signal any stronger, and might distort your transmission.

5.  When you finish, transmitting, release the microphone talk button.
    You can now receive transmissions.

6.  To turn off the TRC-488, turn VOLUME counterclockwise until you hear
    it click.
