Taking Care of Your EV-A50
Video Head Cleaning
When playback pictures are noisy and hardly visible, or no picture or mono-colored
screen appears, the video heads may be contaminated. In such a case, clean the
video heads using video head cleaning tape V8-25CLH (not supplied) or ask Sony
service personnel to clean the video heads.

Worn Video Heads
If the VCR displays a poor picture after you clean the video heads, you may need to
replace them. Consult your dealer or the Sony Service Center nearest you.
Check the Video Heads after 1,000
Hours of Use
This VCR is a high-precision machine. It must record on or play back from magnetic
tapes on which the image signals from the color TV or the video camcorder are
recorded.
The video head or mechanical parts for transporting the tape become contaminated
or worn after extended use. You should have the VCR checked (cleaning, oiling and
replacing of worn parts) after each 1,000 hours of use.
Moisture Condensation
¢ Main Unit
Do not operate the unit right after having transported it from a cold location to a
warm location or in a room where the temperature rises suddenly, because
moisture may condense in the operating section of the unit. Wait for about an hour
before turning the power on in the new location or keep the rise in room
temperature gradual. If the unit is operated with moisture condensation, the unit
and the tape may be damaged.
Therefore remove the tape immediately when there is a possibility of moisture
condensation and no picture (or a mono-colored picture) is obtained. To
evaporate the moisture rapidly, leave the player turned on without a tape loaded.
¢ Cassette
When a cassette tape is carried from a cold place to a warm place, the cassette
tape may become wet. When there is any possibility of moisture condensation,
eject the cassette tape and leave it outside of the compartment for about one
hour.
