(210-1703A)                Care and Maintenance       Faxback Doc. # 60708

Your RadioShack TRC-503 40 Channel Mobile CB Radio with Channel 9/19
Priority Switch 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.

  Use and store the CB only 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.

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

  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-503's 2-amp in-line fuse helps protect your CB from power surges
and short circuits.  When replacement is required use a 2-amp, slow-blow
glass fuse, available at your local RadioShack store.

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 and inspect its condition.  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.
