Video head cleaning

Video head clogging

The video heads are the means by which the DVD/VCR 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
back. This can easily be determined if, during playback of a known
good tape, there is good sound, but no picture (picture is extremely	Normal	When head is dirty
snowy). If this is the case, have the DVD/VCR checked by qualified
service personnel.

NOTES:

•DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE TOP COVER.

•Video heads may eventually wear out and should be replaced when they fail to produce clear pictures.

•To help prevent video head clogging, use only good quality VHS tapes. Discard worn out tapes.

•We do not recommend using wet-type head-cleaning cassettes as they may damage the unit.
