JVC GY-DV5100 Routine and Periodical Maintenance, Precautions for Use of Head Cleaning Tape

1. INTRODUCTION

1-2 Routine and Periodical Maintenance

The GY-DV5100 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”.) 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.

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.

For consultations related to the maintenance planning or cost, please contact the person in charge of professional video equipment at your nearest JVC-authorized service agent.

1-3 Precautions for Use of Head Cleaning Tape

Please use cleaning tape produced by JVC.

Adhere to the following precautions when using the head cleaning tape.

1.Insert the cleaning tape. Press the PLAY button after the cleaning tape is fully loaded. The tape runs for 10 seconds at a time in the PLAY mode. (The tape stops automatically and then the unit enters the STOP MODE.)

2.Do not use the tape more than four times at the most for each cleaning.

Use the following chart as a guide for periodical head cleaning.

Note 1) When used in a low humidity environment, head cleaning should be conducted at intervals half of those given in the below chart.

Note 2) If an ME80 tape is used immediately after head cleaning, the “HEAD CLEANING REQUIRED!” indicator may remain on. In this case, let the tape run as the indicator will turn off after the tape has run for a while.

Note 3) Use the cleaning tape in the room temperature (10˚C to 35˚C).

Note 4) The cleaning tape case contains instructions for use of the cleaning tape. However, some of these instructions differ from the contents of this sheet. When using the cleaning tape, please follow the instructions of this sheet.

Note 5) If the “HEAD CLEANING REQUIRED!” does not disappear after repeated head cleanings, the recording tape may be abnormal. Avoid excessive repeated use of the head cleaning tape.
