Video head cleaning

This VTR is equipped with an auto head cleaning function which automatically reduces the amount of dirt on the video heads. In order to maximize the VTR’s reliability, however, it is recommended that the video heads be cleaned as and when appropriate.

For further details on how to actually clean the heads, consult with one of Panasonic’s service companies or with your dealer.

Condensation

Condensation occurs due to the same principle which is involved when droplets of water form on a window pane of a heated room. It occurs when the VTR or tape is moved between places where the temperature

or humidity varies greatly or when, for instance:

It is moved to a very humid place full of steam or a room immediately after it has been heated up.

It is suddenly moved from a cold location to a hot or humid location.

After moving the VTR to such a location, leave it standing for about 10 minutes rather than switching on

its power immediately.

If condensation has formed on or in the VTR, the AUTO OFF lamp lights, and the cassette tape is

automatically ejected. Keep the power supplied and simply wait until the AUTO OFF lamp goes off.

It is recommended that the video heads be cleaned after the AUTO OFF lamp has gone off.

Maintenance

Before proceeding with maintenance, be absolutely

sure to set the power switch to OFF and take hold of the power plug and unplug it from the power outlet.

Use a soft cloth to clean the cabinet. To remove stubborn dirt, dilute some kitchen detergent, dip a cloth into the solution, wring it out well, and wipe. After having removed the dirt, take up any remaining moisture using a dry cloth.

<Note>

Do not use alcohol, benzene, paint thinners or other solvents. They can discolor the external parts surfaces and remove the finish.
