Driving system parts

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

: Check or replace as required. If replacement is

not required, clean it.

: Replace.
