Cleaning tape

Use a JVC cleaning tape.

Follow the instructions below for using the clean- ing tape.

1.Run the tape for 10 seconds in the PLAY mode. (Thereafter, it stops automatically and enters the STOP mode.)

•After loading the cleaning tape, press the PLAY button.

2.For a single cleaning session, it can be repeated up to 4 times.

3.Refer to the following table as a guide for cleaning.

Note

zUnder low humidity conditions, (10% RH to 30% RH), perform head cleaning at intervals of half of the periods stated in the table.

zIf an M-DV80 tape is used immediately after cleaning, the message, “HEAD CLEANING REQUIRED!” may not disappear. It does only after the tape has run for some time.

zUse the cleaning tape at room temperature (10°C to 35°C).

zInstructions for using the cleaning tape stated on a sheet inside its storage case may be dif- ferent in part from those stated here.

Follow the instructions in this manual.

Condensation

•When this unit is moved from a cold to a warm place abruptly, the vapor in the warm air will come into contact with the head drum or the tape guides, which are not warmed enough. When chilled, the vapor turns into droplets of water. This state is known as condensation. When condensation occurs, the videotape adheres to the head drum or the tape guides and will be damaged.

•Condensation occurs on this unit in the fol- lowing circumstances:

* It is moved abruptly from a cold place to a warm place.

* It is used in a place immediately after the heater has been turned on, or when cold breeze from an air-con- ditioner blows onto it.

*It is used at a place of high humidity.

When a cassette tape is loaded, do not transport e.g., from a cold outdoor place to a warm room thus subjecting the unit to drastic temperature changes. After moving the unit, do not use it until the inner mechanism stabilizes.

•When condensation occurs, the monitor displays the following warning:

CONDENSATION ON DRUM

Leave the unit with the power ON and wait until the WARNING message disappears.

•Prevention of condensation

When transporting BR-HD50 from a cold to a warmer place abruptly, first remove the cassette tape. Then place BR-HD50 in a plastic bag and seal it before transporting.

Take out BR-HD50 from the sealed plastic bag only after it has the same temperature as the surroundings.
