1-1 Major Features

1 INTRODUCTION

1-2 Periodical Maintenance

This VCR incorporates precision mechanical parts which will collect dirt over time and ultimately deteriorate and wear out. Over long periods of use, dirt and dust accumulates on the heads, drums and tape transport mechanisms. Dust which penetrates the VCR (especially during outdoor use) also promotes the wear and deterioration of mechanical parts by causing poor contact between tape and heads. This also prevents the VCR from maintaining video and audio quality at high levels. To prevent wear and deterioration, clean the heads regularly using a head cleaning tape. However, because a head cleaning tape alone cannot clean the entire tape transport mechanism, this should also be inspected periodically to prevent any problems that could result from a sudden failure.

As replacement and adjustment of parts require advanced skills and specialized equipment, please contact the person in charge of professional video equipment at your nearest JVC-authorized service agent for servicing.

Monitoring Usage Time

Periodic Maintenance

The total operation time reached by an ordinary home VCR in 5 or 6 years may be reached by a professional VCR in as few as 5 or 6 months. Therefore, it is important that the total hours of operation be carefully monitored. An hour meter in the on-screen display (see page 18) shows the accumulated time. In the chart below, the hours accumulated in each month are shown in relation to the number of hours used per day. Times shown inside shaded area indicate that maintenance should be performed.

Check or replace the following mechanical parts according to the running time.

1-3 Precautions

Handle the unit carefully

• Do not place anything heavy on the unit (a monitor, etc.). A malfunction may occur.

• Do not put any foreign substance into the cassette loading slot.

• Avoid violent shocks to the recording chassis during transportation. Remove the cassette tape from the unit for transportation.

Turn off the power to save electricity when not using the unit.

Handling and storage place

Avoid using the unit in places subject to the following conditions:

• extreme heat or cold

• strong magnetic fields (do not use a transceiver within

2 meters of this unit)

• high humidity

• dust and soil

• vibrations

• variations in temperature

Use this unit in horizontal (flat position) only.

Do not leave the unit in the Still or Record Pause mode for a long time as this may damage the tape.

To minimize tape damage, this VCR automatically

enters the Stop mode after about 5 minutes have passed in the Still or Record Pause mode.

Video cassette

• Only use video cassette bearing the

PAL

mark.

• To prevent accidental erasure of a recorded tape, break the erasure prevention tab on the cassette. To use a cassette with a broken tab, place a piece of cellophane tape over the broken tab.

• Video cassettes cannot be used upside down.

• Leaving the tape in a partially wound condition for a long

time may damage the tape. Rewind the tape to the beginning before storage.

Timelapse recording is performed over very long periods of time which means that a durable tape is required.

•

Use an E-180 tape or shorter.

•

Do not use extended tapes (180 minutes or more such as E-240).

Erasure prevention tab

Condensation

Condensation occurs in the following cases.

• When the VCR is moved from a cold place to a warm place.

• In a room that has just been heated or in an area directly exposed to a cooler.

• When there is excessive humidity

When condensation is expected to occur

Turn the power of the VCR on before use.

Condensation

When cold beer is poured into a glass, water drops appear on the glass

’s surface. This phenomenon is called “condensation”. When condensation occurs on the VCR’s head drum and tape guides it may damage the tape.
