(160-0429)                 Care and Maintenance       Faxback Doc. # 50435

Your Optimus Model 36 9" Color TV/VCR Combo is an example of superior
design and craftsmanship.  The following suggestions will help you care
for your Model 36 so you can enjoy it for years.

  Keep the Model 36 dry.  If it gets wet, wipe it dry immediately. 
  Liquids might contain minerals that can corrode the electronic circuits.

  Use and store the Model 36 only in normal temperature environments.
  Temperature extremes can shorten the life of electronic devices, damage
  batteries, and distort or melt plastic parts.

  Keep the Model 36 away from dust and dirt, which can cause premature
  wear of parts.

  Handle the Model 36 gently and carefully.  Dropping it can damage
  circuit boards and cases and can cause the Model 36 to work improperly.

  Use only fresh batteries of the required size and recommended type.
  Batteries can leak chemicals that can damage your Model 36's electronic
  parts.

  Wipe the Model 36 with a damp cloth occasionally to keep it looking new.
  Do not use harsh chemicals, cleaning solvents, or strong detergents to
  clean the Model 36.

Modifying or tampering with the Model 36's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it.  If you Model 36 is not performing as it
should, take it to your local RadioShack store for assistance.

THE FCC WANTS YOU TO KNOW

This equipment has been tested and found to comply with the limits for a
class B digital device, pursuant to Part 15 of the FCC Rules.  These
limits are designed to provide reasonable protection against harmful
interference in a residential installation.  This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference
and radio communications.

Your Model 36 might cause radio and TV interference even when it is
operating properly.  To determine whether your Model 36 is causing the
interference turn off your Model 36.  If the interference goes away, your
Model 36 is causing it.  Try to eliminate the interference by:

  moving your Model 36 away from the receiver.

  connecting your Model 36 to an outlet that is on a different electrical
  circuit from the receiver.

  contacting your local RadioShack store for help.

If you cannot eliminate the interference, the FCC requires that you stop
using your Model 36.

REPLACING THE DC ADAPTER'S FUSE

If the Model 36 stops operating when the DC adapter is connected, the fuse
in the DC adapter might be blown.  Follow these steps to check and replace
it with a 5-amp, 1-1/4" x 1/4", fast-acting fuse (RadioShack Cat. No.
270-1011, not supplied).

CAUTION:  Using a fuse that does not meet these ratings or defeating the
          fuse protection can damage your Model 36, the DC adapter, and
          the vehicle's electronic system.

1.  Grasp the ring near the tip of the plug, then carefully unscrew the
    ring by turning it counterclockwise.

    CAUTION:  If you must use pliers to loosen the ring, be careful not
              to crush the tip.  Never use pliers or other tools to
              retighten the ring on the plug.

2.  Pull the ring straight out, then remove the metal tip and old fuse.

3.  Check the fuse to see if it is blown.  If it is, replace it with a
    new fuse.  If it is not, put the fuse back into the fuse holder.

4.  Replace the metal tip inside the ring, then place the fuse inside the
    cigarette-lighter plug and screw the ring back onto the plug.  Make
    sure that the metal tip is visible which you reassemble the cigarette
    lighter plug.

SERVICING YOUR MODEL 36

There are no user-serviceable parts inside your Model 36.  If you
encounter a problem that you cannot correct using this manual and its
troubleshooting guide, take the Model 36 to your local RadioShack store
for assistance.

Cleaning the Video Heads

Although the Model 36's automatic head cleaning system helps keep the
video heads clean, the video heads will require additional cleaning after
long use.  Dirty video heads cause the playback picture to blur, even if
the recorded signal is clear.  However, video head cleaning is a delicate
operation that requires a trained technician.  For more head cleaning
information, contact your local RadioShack store.

Have the video heads cleaned only when picture quality is affected.

STORING VIDEO CASSETTES

Unless you are making a timer recording, eject and store the cassette when
you finish using it.  This helps protect the cassette and the Model 36's
internal mechanisms from dust.

Place your video cassettes in your protective boxes and store them in a
cool, dry, dust-free environment.  Store the cassettes on end, not on
their sides.  This prevents improper setting of the cassette's spools.

Note:  Tape can become wound too tightly around the cassette's spools
       after you play a tape several times.  This can cause the cassette
       to improperly load and automatically eject when you insert it.  On
       most cassettes there is a brake release plunger on the bottom
       center of the cassette.  Use the tip of a pen or pencil to press
       the plunger.  This loosens the tape.

DEGAUSSING

Your Model 36 has an automatic degauss circuit.  The circuit functions
each time you turn the power off.  However, strong magnetism from nearby
appliances might affect the Model 36's picture.  If this happens, move the
Model 36 away from the appliance.  If the Model 36's picture is still
affected, turn the power off for 30 minutes, then turn it back on.  If
the Model 36's picture is still affected, contact your local RadioShack
store for assistance.
