(190-1104)                 Care and Maintenance       Faxback Doc. # 61419

Your RadioShack HTX-400 Mini Handheld 70-Centimeter FM Amateur Transceiver 
is an example of superior design and craftsmanship.  The following 
suggestions will help you care for your transceiver so you can enjoy it 
for years.

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

  Use and store the transceiver only in normal temperature environments.
  Temperature extremes can shorten the life of electronic devices, damage 
  batteries, and distort or melt plastic parts.

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

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

  Use only fresh batteries of the required size and recommended type.
  Batteries can leak chemicals that damage your transceiver's electronic
  parts.

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

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