VCR Care and Servicing   
 
 
 
 
 
 
 
The VCR is fairly self-servicing, but you'll want to keep an eye on a few 
things as you go. In addition, you may sometimes have troubles with your 
VCR.  We offer some suggestions for care to prevent problems, ways to 
troubleshoot, and places to contact when you cannot solve the problems 
yourself. 
 Routine Cleaning 
Head Cleaning 
The heads are tiny mechanisms in the VCR that pick up the video signal 
as a videotape passes over them.  In time, a residue of electromagnetic 
dust builds up on the heads because of contact with the tape.  This dust 
interferes with the signal being picked up. 
Your Hitachi VCR automatically cleans the video heads whenever a 
cassette is loaded or ejected and when a cassette is already inside the 
VCR when you turn the power off.  It also self-cleans during fast-forward 
and reverse play. You will hear a mechanical sound during auto head 
cleaning. 
Even with the auto head cleaning system, dirt can build up on the heads.  
If the picture is blurry during playback, or is occasionally interrupted or 
blanks out, try playing different cassettes to see whether you get the same 
picture problems. 
If the picture problems persist, the heads may need to be cleaned 
professionally. Consult your VCR dealer for the name of trained service 
technician near you. 
Periodic Maintenance 
Your Hitachi VCR is a precision electro-mechanical device which requires 
professional maintenance after a period of normal use. 
Usually no maintenance other than head cleaning is required during the 
warranty period, unless the VCR is used either heavily or infrequently.  
Defective parts are covered during the warranty period, but normal 
maintenance is your responsibility. 
Consult your VCR service center to find out what they recommend as 
normal maintenance based on your location, how you use the VCR and 
the age of the machine. 
 If the VCR Doesn't Work Right 
Many operational problems are easily remedied by reviewing the 
instructions in this manual and trying out some different controls and 
settings. The chart on page 62 covers the more common problems that 
new VCR owners encounter. 
Don't Attempt Repairs Yourself 
Do not remove the cover or the back of the VCR - this will void the 
warranty and endanger your safety. The exposed uninsulated voltage in 
this unit may be high enough to cause electrical shock. It is dangerous to 
make contact with any inside part, and none of these parts are intended to 
be serviced by an untrained user. To be safe, refer service problems to
