Maintenance
Automatic Head Cleaning
Your video recorder has a built-in head cleaner that automaticallly cleans the _6deo head drum assemb-
ly whenever a tape is loaded or unloaded. This Auto Head Cleaner reduces head clogging.
Video Head Cleaning
After long periods of use, the video heads may become clogged with accumulated
dirt, causing distor-
tion. When this occurs, use do-it-yourself wet head cleaning cassettes available through your Zenith
dealer.
CALrHON:
Do not use dry head cleaning systems. They may seriously damage both the video recorder
and cassette. When visual signs appear (snow, streaking in picture and horizontal pulling of picture) in-
dicating the need for video head cleaning, please see your Zenith approved selvice center.
Cabinet Cleaning
The outside surfaces of the video recorder may be cleaned with a soft lint-free cloth as required.
Use
care not to scratch the VCR message center window during cleaning.
