(210-0527)                 Care and Maintenance       Faxback Doc. # 47599

Your RadioShack Digital Standing Wave Ratio and Power Meter is an example
of superior design and craftsmanship.  The following suggestions will help
you care for the meter so you can use it for years.

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

  Handle the meter gently and carefully.  Dropping it can damage its
  circuit board and case and can cause it to work improperly.

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

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

  Occasionally wipe the meter with a damp cloth to keep it looking new.
  Do not use harsh chemicals, cleaning solvents, or strong detergents
  to clean the meter.

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

TEST AND CALIBRATION MODES

Your meter has two special modes for testing and calibration.  To place
the meter in the test mode, hold down the POWER key while you plug in the
meter's adapter.  All display segments turn on.  To return the meter to
normal operation, release the key.

To place the meter in the calibration mode, hold down the SWR key while
you plug in the meter's adapter.  The meter displays tESt.  To return the
meter to normal operation, unplug the adapter, then plug it back in.

Note:  Calibration procedures require special equipment and are covered
       in the Service Manual, available by special order from your local
       RadioShack store.
