(210-1572A)                Installation               Faxback Doc. # 40685

Mounting The Microphone Holder

Using a Phillips screwdriver and the supplied screws and washers, attach
the supplied microphone holder to the CB's left or right side either hori-
zontally or vertically.

Connecting The Microphone

1.  Align the slot on top of the microphone's plug with the ridge inside
    the MIC jack.  Then fully insert the plug into the jack.

2.  Turn the plug's locking nut clockwise to tighten it.

3.  Slide the microphone onto the microphone holder.

To disconnect the microphone cable; unscrew the locking nut and gently pull
out the microphone plug.

CAUTION:  Never pull on the microphone cable.

Mounting The TRC-444

The most common mounting location for this CB is under a vehicle's dash-
board.  However, if you use the TRC-444 as a base station, you can place it
on a desk, shelf, or table (see "Using the CB as a Base Station").

If you are mounting the CB in a vehicle, choose a location where:

  You can easily reach the CB.

  Wires and cables will not interfere with the vehicle's pedals or other
  moving parts.

  The CB is not directly in front of heating vents.

  All wires and cables will reach their connection points.

CAUTIONS:  The TRC-444 is designed to work in a vehicle that has a 12-volt
           DC, negative ground electrical system.  Most vehicles have this
           type of system.  If you are not sure about your vehicle, check
           with your vehicle dealer.

           If you use the TRC-444 in a vehicle, mount it securely to avoid
           damage to the CB or vehicle or injury to anyone in the vehicle
           during sudden starts or stops.

Follow these steps to mount the CB using the supplied hardware.

1.  Using the mounting bracket as a template, mark the positions for the
    screw holes using the slots in the mounting bracket.

2.  In each marked location, drill a hole slightly smaller than the supplied
    mounting screws.

    CAUTION:  Be careful not to drill into anything behind the mounting
              surface.

3.  Using a Phillips screwdriver, attach the mounting bracket to the mount-
    ing surface with the supplied mounting screws and lock washers.

4.  Attach the CB to the mounting bracket using the rubber washers and
    mounting knobs.

Installing An Antenna

CAUTION:  To prevent damage to your CB, you must connect an antenna to the
          CB before you operate it.

Selecting an Antenna

When deciding on an antenna and its location, consider these points:

  The location of the antenna should be as high as possible.

  The antenna and antenna cable should be as far as possible from sources
  of electrical noise (ignition systems, gauges, etc.).

  The antenna should be vertical for the best performance.

Your local Radio Shack store sells a variety of CB antennas for both mobile
and base-station use.  Choose the one that best meets your needs.

Connecting an Antenna

Once you choose an antenna, follow the mounting instructions supplied with
the antenna.  Then route the antenna cable to the CB and connect the cable
to the ANTENNA jack on the back of the CB.

CAUTIONS:  Do not run the cable over sharp edges or moving parts that might
           damage it.

           Do not run the cable next to power cables or other CB antenna
           cables.

           Do not run the cable through a vehicle's engine compartment or
           other areas that produce extreme heat.

           To prevent possible damage to your CB and to ensure the best
           operation, you should adjust the standing wave ratio (SWR)
           between the antenna and the CB to the lowest possible level
           (see "Maximum Range").

Using Vehicle Battery Power

You can power this CB from your vehicle's battery or from standard AC power
with an optional DC power supply.  For information on using AC power, see
"Using the CB as a Base Station."

Follow these steps to power the CB from your vehicle's battery.

1.  Connect the black wire to your vehicle battery's negative (-) terminal
    or to a metal part of the vehicle's frame that is not insulated from
    the frame by a plastic part.

2.  Connect the red wire, with in-line fuse, to a source of voltage that
    turns on and off with the ignition switch, such as a spare accessory
    terminal in your vehicle's fuse box.

3.  Connect the orange wire, with in-line fuse, to a source of voltage that
    supplies constant positive (+) power, or directly to your vehicle's
    positive (+) battery terminal.  This connection is for last-channel
    memory backup.
