Maintenance information and precautions
Moisture condensation
If the camcorder is brought directly from a cold place to a warm place, moisture may
condense inside the camcorder, on the surface of the tape, or on the lens. In this
condition, the tape may stick to the head drum and be damaged or the unit may not
operate correctly. To prevent possible damage under these circumstances, the
camcorder is furnished with moisture sensors. Please, take the following precautions.
Inside the camcorder
If there is moisture inside the camcorder, the beep sounds and the SI indicator flashes.
If this happens, none of the functions except cassette ejection will work. Open the
cassette compartment, turn off the camcorder, and leave it about 1 hour. When ^
indicator flashes at the .same time, the cassette is inserted in the camcorder. Eject the
cassette, turn off the camcorder, and leave also the cassette about 1 hour. The camcordt
can be used again if the 31 indicator does not appear when the power is turned on
again.
On the lens
If moisture condenses on the lens, no indicator appears, but the picture becomes dim.
Turn off the power and do not use the camcorder for about 1 hour.
How to prevent m'oistiire condensation
When bringing the camcorder from a cold place to a warm place, put the camcorder in
plastic bag and allow it to adapt to room conditions over a period of time.

Remove the bag when the air temperature inside it has reached the
temperature surrounding it (after about 1 hour).
Video head cleaning
To ensure normal recording and clear pictures, clean the video heads. When the
O indicator and " ^ CLEANING CASSETTE" message appear one after another in thi
viewfinder or playback pictures are "noisy" or hardly visible, the video heads may be
dirty.

If this happens, clean the video heads with the Sony V8-25CLH cleaning cassette (not
supplied). After checking the picture, if it is still "noisy," repeat the cleaning. (Do not
repeat cleaning more than 5 times in one session.)
Caution
Do not use a commercially available wet-type cleaning cassette. It may damage the
video heads.
Note
If the V8-25CLH cleaning cassette is not available in your area, consult your nearest
Sony dealer.
