Wipe the front panel and other exterior surfaces of the VCR with a soft cloth
immersed in lukewarm water and wrung dry.
Never use a solvent or alcohol. Do not spray insecticide liquid near the VCR. Such
chemicals may cause damage and discoloration to the exposed surfaces.
HEAD CLEANING
Picture playback may become blurred or interrupted while the TV program reception
is clear. This does not mean that the recorded program has been erased. Dirt
accumulated on the video heads after long periods of use, or the usage of rental or
worn tapes can cause this problem. If a streaky or snowy picture appears during

Audio/Video store and purchase a good quality VHS Video Head Cleaner. Remember
to read the instructions included with the head cleaner before use. Clean heads only
when problems occur. If this does not correct the problem, consult the nearest
Authorized Service Center. Professional video head cleaning requires highly technical
