Routine And Periodical Maintenance - JVC GY-DV5000 Instructions Manual

1-2 Routine and Periodical Maintenance

The GY-DV5000 incorporates precision mechanical parts, which will collect dirt, wear out and deteriorate as the unit is used. After
the unit has been used for a long period even in a normal environment, the heads, drums and tape transport mechanisms also
collect dirt. Especially, dust which penetrates the inside of the VCR section during outdoor use will promote the wear and deterioration
of mechanical parts by causing poor contact between tape and heads or failing to maintain the video and audio quality at high
levels. To prevent wear and deterioration, clean the mechanical parts using a head cleaning tape as routine maintenance. However,
cleaning with a head cleaning tape alone is not enough for cleaning the entire tape transport mechanism, so it is also recommended
to apply periodical maintenance (inspection) to prevent the sudden occurrence of failure. As the replacement, adjustment and
servicing of parts require advanced skill and equipment, please consult the person in charge of professional video equipment at
your nearest JVC-authorized service agent.
Head Cleaning
● To maintain beautiful pictures and sound, be sure to use a
head cleaning tape to clean the head periodically. (Read the
"Precautions for Use of Head Cleaning Tape" on page 8.) If
head cleaning is not performed periodically, a type of mosaic
noise called block noise may appear in the picture or sound
may be interrupted.
Block Noise
● Please use cleaning tape produced by JVC. Do not use head
cleaning tapes other than specified. Read the precautions
and instructions for use of the head cleaning tape on page 8.
● When dust adheres to the heads, the warning message
"HEAD CLEANING REQUIRED!" is displayed on the LCD
monitor and in the viewfinder during playback, edit search,
and recording check using the RET button on the lens section.
