INTRODUCTION Precautions for Proper Use (Cont'd) ● Do not set the POWER switch to OFF or remove the power cord during recording or playback. Otherwise the tape may be damaged. ● When the unit is not in use, be sure to set the POWER switch to OFF in order to reduce power consumption. ● Cleaning the camera body: Wipe the body with a dry, soft cloth. When it is extremely dirty, soak the cloth in a solution of neutral detergent, wring it out and then wipe. To prevent deformation of the body, etc. and to avoid operation hazards, do not allow volatile liquids such as benzene and thinner to contact the body, and do not wipe it with a cloth soaked in such a liquid. ● The camera may be unstable for a few seconds immediately after the power is turned on, but this is not a malfunction. CAUTION ● Do not point the lens or viewfinder directly at the sun or other strong light source • Eye damage could result. • If the lens or viewfinder is left pointed at the sun, rays may collect inside the unit and cause damage or a fire. ● When carrying the camera, be sure to hold the carrying handle. Holding the LCD door, lens or viewfinder may result in damage. 8 TENTATIVE Routine and Periodical Maintenance The GY-DV300 incorporates precision mechanical parts, which will collect dirt, wear out and deteriorate as the unit is used. On the other hand, when the unit has been used for a long period in a normal environment, the heads, drums and tape transport mechanisms also accumulate dirt that is deposited on them. Furthermore, dust which penetrates the inside of the VCR section especially during outdoor use will promote the wear and deterioration of mechanical parts by causing poor contact between tape and heads or failure 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, as cleaning with a head cleaning tape alone is not enough for cleaning the entire tape transport mechanism, it is also recommended to apply periodical maintenance (inspection) to prevent troubles that may be caused by 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 video and sound, be sure to use a head cleaning tape to clean the head periodically. (Read "Precautions for Use of Head Cleaning Tape" on page 10.) 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 ● Use the optional head cleaning tape M-DV12CL. Do not use other than the designated head cleaning tapes. For instructions on how to use the head cleaning tape and precautions for its use, read "Precautions for Use of Head Cleaning Tape" on page 10. ● When dirt adheres to the video heads of the GYDV300, the warning message "HEAD CLEANING REQUIRED!" appears on the LCD screen and the viewfinder screen during edit search in the recording mode and during playback. Periodical Maintenance Contents: Check or replace the following mechanical parts according to the running time.
