RECEPTION DISTURBANCE/VIDEO HEAD CLOGGING
IGNITION
Black spots or horizontal streaks may appear, picture may flutter or drift. Usually caused
by interference from car ignition systems, neon lamps, electrical drills and other electrical
appliances.
GHOSTS
Ghosts are caused by the television signal following two paths. One is the direct path and
the other is reflected from tall buildings, hills or some other object. Changing the direction
or position of the antenna may improve the reception.
SNOW
If your receiver is located in the fringe area of a television station where the signal is weak,
your picture may be marred by the appearance of small dots. When the signal is
extremely weak, it may be necessary to install a special antenna to improve the picture.
RADIO FREQUENCY INTERFERENCE
The interference produces moving ripples or diagonal streaks, and in some cases,
causes loss of contrast in the picture.
PICTURE SIZE VARIATION
A slight picture size variation is normal when you adjust the CONTRAST or BRIGHT-
NESS control.
CARE AND MAINTENANCE
To prevent fire or shock hazard, disconnect the unit from the AC power source before cleaning. The finish on the
cabinet may be cleaned with mild soap and a soft damp cloth. Take care when cleaning or wiping the plastic parts.
VIDEO HEAD CLOGGING
The video heads record and playback picture and sound on the video tape. In the event that they become
dirty you won't be able to do a perfect recording and the playback picture will be extremely snowy with
good sound. If this happens have the unit checked by qualified service personnel.
NOTES:
Video heads may eventually wear out and should be replaced when they fail to produce clear pictures.
To help prevent video head cleaning, use only good quality VHS tapes. Discard worn tapes.
