VIDEO HEAD CLEANING SPECIFICATIONS
VIDEO HEAD CLOGGING
The video heads are the means by which the TVNCR reads the picture from the tape during playback. In the
unlikely event that the heads become dirty enough to be clogged, no picture will be played beck. This can easily be
determined if, during playback of a known good tape, there is good sound, but no picture (picture is extremely
snowy). If this is the case, have the TV/VCR checked by qualified seP..tcepersonnel.

VIDEO HEAD CLEANING
AUTO HEAD CLEANING system cleans the video heads automatically when a cassette is inse_ed or ejected to
prevent dirt from accumulating on the heads. However, manual head cis_niog is needed if the picture on playttack is

when playing poor quality or damaged tapes. If the heads require cleaning, use a high qualify head cleaning system
