The video cassette recorder/player incorporates precision components. Regular maintenance is necessary to
maintain the performance level required for professional use. The information below will help you determine a
maintenance schedule that will ensure optimum performance over a long period of time.
● Maintenance
Just as regular oil changes, brake checks, and
tune-ups are essential to keep your car running well
over a long period, your VCR must be maintained
regularly to ensure optimum long-term
performance.
Continued use of the VCR without maintenance
may lead to the following malfunctions.
● Recording or playback cannot be executed.
● Picture and sound distortion.
● Repeated warnings (stopping the operation).
These malfunctions are mostly due to wear or
deterioration of the VCR's internal components.
Having these repaired can be expensive.
Moreover, a sudden malfunction can not only lead
to downtime and lost productivity, but can also
damage the video cassette.
1-2 MAINTENANCE
This table should be used as reference only. Actual maintenance requirements will vary according to how the unit
is used.
Maintenance consultation
Consult your local JVC dealer for more information about maintenance scheduling and costs.
1 INTRODUCTION
● Keeping track of operation (running) time
The total operation time reached by an ordinary
home VCR in five to six years may be reached by a
professional VCR in as few as five to six months.
Therefore, it is important to closely monitor the total
operation time. You can check the running time on
the provided hour meter (drum running time). The
hour meter is shown on the counter display or on-
screen display on the monitor.
Hour meter indication
The hour meter can be displayed by selecting
“DRUM HOUR” on the menu switch setting screen.
For details, refer to “Hour meter indication” on page
39.
● Maintenance schedule
Depending on the operation time, inspect or
replace the following mechanism components.
Replace the drum assembly (including the heads)
and head cleaner every 750 hours.
ଁ: Cleaning, check and adjustment
⅜: Check or replace as required. If replacement is
not required, clean it.
ⅷ: Replace.
