ABOUT HEAD CLEANING
After an extended period of use, the video heads can become dirty, resulting in a loss of picture or sound during
playback. If this happens, clean the video heads by using the optional cleaning tapes.
Symptoms of dirty video heads:
The picture is not clear, or does not appear.
There is no sound.
Mosaic (block) noise appears in the picture.
Black or mosaic horizontal stripes appear in the
picture.
The picture stops (as if the tape is paused).
A blank black or blue screen appears.
The picture is fuzzy. (VHS playback)
Use a cleaning tape designed specifically for D-VHS video heads (JVC D-VHS video head cleaner DFC-2) to clean the video heads.
In order to avoid misoperation, set "NAVIGATION" to "OFF" ( pg. 43).
Follow the instructions that are provided with the cleaning tape.
If you still do not get a clear picture after using a cleaning tape:
The heads may be worn. Contact your nearest JVC dealer.
During VHS playback, if there is a tracking problem, the picture may appear fuzzy. Adjust the tracking manually ( pg. 23).
