6-2 Maintenance

6-2-1 Condensation

The water vapor in the air may form as tiny droplets on the head drum when the unit is moved from a cold location to a warm location or used in a very humid place. This phenomenon is known as condensation, and running the tape under these conditions is liable to cause the tape to stick to the drum.

Note the following points:

≥Remove the tape when the unit’s operation is to be started in conditions where condensation may form.

≥Before loading the tape, set the power switch to ON, and check that the HUMID display is not lighted in the display window.

<Note>

For safety reasons, the HUMID display will flash and the drum will rotate for 80 minutes after condensation detection is released.

During this time, the operation buttons cannot be operated.

6-2-5 Replacing the backup battery

The backup battery is already installed when the unit is shipped.

When it has discharged, the “BACK UP BATT EMPTY” display appears for 3 seconds on the viewfinder screen when the POWER switch is set to ON.

Moreover, the time code value of the TCG will be set to “00:00:00:00” and the backup of the time code value will no longer be possible: this means that the backup battery should be replaced.

Consult with your nearest service center, and replace the spent battery with a new battery (CR2032).

6-2-2 Head cleaning

Use the AJ-CL12MP cleaning cassette if the heads need to be cleaned. Take care to read the instructions accompanying the cleaning tape since the video heads may be damaged if the tape is not used in the correct way.

6-2-3 Cleaning inside the viewfinder

≥Do not use thinners or any other solvent to remove dirt.

≥Use a lens cleaner available on the market to wipe the lens.

≥NEVER wipe the mirror.

If dirt or dust has found its way onto the mirror, remove it using an air blower at retail outlets.

6-2-4 Phenomena inherent to CCD cameras

Smear

This phenomenon may occur when very bright subjects are shot.

The faster the electronic shutter speed, the more likely it is that it will occur.
