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 its sapphire edge.

Head Condition Sensor

The Head Condition Sensor checks the condition of the video heads. 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. You may have to manually adjust the tracking to get a better picture (see “Adjusting the picture” on page 46). 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).
