1-4 Precautions for use of head cleaning tape

Installation and storage

5 To avoid malfunctions or damage to your recorder, do not use or store it in places subject to the following conditions.

–Extreme heat or cold — temperature outside the allowable range (5˚C to 40˚C)

–Strong magnetic fields (generated by transformers, motors, etc.)

–Electrical waves generated by equipment such as a transceiver or cellular phone

–High humidity — outside the allowable operating range (30% to 80%)

–Dust and soil

–Vibrations

–Condensation

Condensation

5 Do not use this unit immediately after moving it from a cold place to a warm place or after switching on a heater in a cold room. This will cause water vapor to condense on the video head drum and tape guides and may damage the tape and the VCR.

5 When condensation occurs, the DEW indication appears on the tape counter display and the warning indication on the on-screen display. Leave the VCR in this state with the power on and wait until the warning message turns off.

Handling

5 Do not block the ventilation openings.

5 Do not place anything heavy on the unit.

5 Do not put any foreign materials into the cassette loading slot. 5 Operate the unit in a horizontal (flat) position only. 5 Avoid violent shocks to the unit.

Transportation

5 Remove the cassette tape from the unit prior to transportation.

Energy saving

5 When not using the unit, turn the power off to avoid unnecessary power consumption.

Cassette tape 5 Type

•Only cassettes bearing the MiniDV mark can be used with this VCR.

•Exclusive JVC DVM60 or DVM30 cassette tape is recommended.

5 Handling

•Cassette tapes cannot be loaded upside-down.

•Rewind the tape to the beginning before storage.

•The number of times a tape can be reused is limited. If the tape is reused more than this, increased noise (such as dropouts) may result. Do not use dirty or damaged tapes. Doing so not only results in poorer performance, but may also shorten the service life of the rotary heads.

•It is possible that some distortion may occur at the beginning and end of tapes. This can vary depending on the tape. However, for best results, do not use these sections of the tape for any important recordings.

•Store cassettes in a case.

Erasure prevention

MiniDV cassettes are provided with a safety slide on the side to prevent accidental erasure. Set it as required.

Safety slide

•Move the slide to SAVE to prevent erasure.

•Move the slide to REC to allow recording.

Power supply

5 This unit is provided with both AC and DC power supplies. For editing over an extended period, it is recommended that you use a stable AC power supply or DC power supply from an AC adapter. Using battery power is recommended only as a supplementary power source or for field use.

5 The AC and DC power supplies are switched automati- cally. When the AC power supply is switched to the DC power supply, the power turns off. When both power supplies are connected, the AC power supply has priority. Be sure to confirm which power supply is in use when plugging or unplugging the power supply.

5 Use power voltage from DC 11 V to 15 V. Your unit may not function properly otherwise.

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.)

Press the PLAY 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.

5 Use the following chart as a guide for periodical head
cleaning.
Operating	Low	Room	High
environment	temperature	temperature	temperature
	5˚C to 10˚C	10˚C to 35˚C	35˚C to 40˚C
Yardstick for	1 to 2 times	1 to 2 times	1 to 2 times
use of	every 5 hours	every 20 to	every 5 hours
cleaning tape		30 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)	When 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 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.

*If you need to purchase a cleaning tape, consult your JVC dealer.
