to insure the peak performance of this products.
1. Periodically make a careful observation of the
quality of the playback video. If there are excess-
ive dropouts (noise specks) across the video pic-
ture, and the TRACKING control does not clear
the picture, then head cleaning may be necess-
ary. Obtain a high quality head cleaning kit, and
follow the directions carefully. The length of
time between cleaning depends on the amount
of airborne contaminates around the tape
recorder and/or cassette.
