TRC-504 40-Channel Mobile CB Radio W/ On-Mic Channel Selector
(210-1704)                 Care and Maintenance       Faxback Doc. # 51500

Your RadioShack TRC-504 40 Channel Mobile CB Radio is an example of 
superior design and craftsmanship.  The following suggestions will help 
you care for your CB so you can enjoy it for years.

  Keep the CB dry.  If it gets wet, wipe it dry immediately.  Liquids can
  contain minerals that can corrode electronic circuits.

  Handle the CB gently and carefully.  Dropping it can damage circuit
  boards and cases and can cause the CB to work improperly.

  Use and store the CB in normal temperature environments.  Temperature
  extremes can shorten the life of electronic devices and distort or melt
  plastic parts.

  Keep the CB away from dust and dirt, which can cause premature wear of
  parts.

Wipe the CB with a damp cloth occasionally to keep it looking new. Do not
use harsh chemicals, cleaning solvents, or strong detergents to clean the
CB.

Modifying or tampering with the CB's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If your CB is not performing as it should,
take it to your local RadioShack store for assistance.

Replacing the Fuse

The TRC-504's 2-amp in-line fuse helps protect your CB from power surges
and short circuits.  When replacement is required us a 2-amp, slow-blow
glass fuse such as Cat. No. 270-1023.

CAUTION:  Do not use a fuse with ratings other than those specified
          here.  Doing so might damage your CB.

Follow these steps to replace the fuse.

1.  Make sure the power source and CB are both off.

2.  Hold the fuse holder by both ends, push the ends together, and twist
    one end counterclockwise, then pull them apart.

3.  Remove the old fuse.  If it is blown, insert a new one of the same type and
    rating.  If it is not blown, reinsert it.

4.  Push the fuse holder ends together and twist one end clockwise.
