INTRODUCTION Precautions for Use of Head Cleaning Tape Use the separately sold head cleaning tape M- DV12CL. Adhere to the following precautions when using the head cleaning tape. 1. The tape runs for 10 seconds at a time in the PLAY mode. (The tape stops automatically and the unit enters the STOP MODE.) ● Set the MODE switch on the unit to "VTR". ● Press the BAR (f/ w) button after the cleaning tape is fully loaded. 2. Do not use the tape more than four times at the most for each cleaning. 3. The cleaning tape can be used approximately 100 times. Use the following chart as a guide for periodical head cleaning. Operating Low temperature Room temperature High temperature environment 0°C to 10°C 10°C to 35°C 35°C to 40°C Yardstick for 1 to 2 times use of cleaning every 5 hours tape 1 to 2 times 1 to 2 times every 20 to 30 hours every 5 hours Note 1) When used in a low humidity environment (10% RH to 30% RH), head cleaning should be conducted at intervals half of those given in the above chart. Note 2) If an ME80 tape is used immediately after head cleaning, the VTR WARNING (HEAD) 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 at 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 given in this document. When using the cleaning tape, please follow the instructions of this document. Note 5) Perform head cleaning before using the GY-DV300 in the LP mode. Videocassette to be Used ● Use JVC videocassette tapes marked with MiniDV for this unit. Please use DVM60 or DVM30 type videocassettes. ● Malfunctions may occur if a DVM80 videocassette is used in the LP mode. ● When recording in the LP mode, use videocassettes bearing the "LP Mode" mark on the package. The following phenomena may occur when tapes recorded in the LP mode are attempted played back on another set. • Noise may appear in the picture and sound • The sound may fall out and the picture may fail to appear • The tape counter indication may be irregular ● Please play back a tape that is recorded in the LP mode on the unit on which the tape was recorded. Also, these tapes cannot be played back on digital video units that do not support the LP mode. ● Videocassettes cannot be used upside down. ● Avoid storing a videocassette with unevenly wound tape, as this may damage the tape. Rewind it to the beginning before placing a cassette into storage. ● Store videocassettes in a place with little humidity and good ventilation where mould does not form. ● After a videocassette tape has been used repeatedly, it becomes unable to maintain full performance due to an increase in noise caused by dropouts, etc. Do not continue to use a dirty or damaged tape, as this will reduce the rotary head life. ● Videocassette tapes marked MiniDV are provided with a switch on the back for use in preventing accidental erasure. ● Slide the switch to "SAVE" to protect the required recording in the tape from being overwritten. ● To record on the tape, slide the switch to "REC".
