Symptoms caused by contaminated video heads
Sapphire tape cleaner
The unit incorporates a sapphire tape cleaner which cleans a video tape when it is
loaded. This cleaner can prevent the video heads from contamination by removing
dust or mold from a tape with the sapphire edge.
Head Condition Sensor
The Head Condition Sensor checks the video heads condition. If the heads are dirty, a
message will instruct you to insert a video head cleaning cassette.
The VCR may temporarily switch to a different head and resume playback. To switch
the heads, press H PLAY while the “PUSH [PLAY] TO RESUME TEMPORARILY”
message appears on the screen. Although playback will resume, the sound will be
monaural. When playback is finished, be sure to clean the heads with a video head
cleaning cassette.
Be sure to use the Sony T-25CLD, T-25CLW or E-25CLDR video head cleaning
cassette. If these cleaning cassettes are not available in your area, have the heads
cleaned at your nearest Sony service facility (a standard service charge will be
required).
