Video Head Cleaning

This VTR comes with an auto head cleaning function which automatically reduces the amount of dirt on the heads. However, to ensure the highest reliability, we recommend that you clean the video heads every day.

Use the cleaning fluid designated by Panasonic.

Checking the hour meter

1

Set the VTR to the remote mode.

 

(Set the LOCAL/MENU/REMOTE switch to the REMOTE position.)

2

When the RESET button on the front panel is pressed, the cumulative numbers of

 

hours during which the drum and capstan have been used are indicated alternately

on the counter display for as long as the button is held down.

Cumulative drum rotation time

Cumulative capstan rotation time

Condensation

The principle according to which condensation forms is the same as that which causes droplets of water (condensation) to form on the window panes of a heated room when it is cold outside. Condensation forms on the VTR or its tape when it is moved to a location with a considerably different temperature and humidity. More specifically, it forms when the VTR or tape is:

Brought into a very steamy and humid location or into a room where the heating was just turned on.

Brought suddenly from an air-conditioned room to a very hot and humid location.

In such cases, do not turn the power on straight away but leave the unit standing for about 10 minutes. When condensation has formed in the unit, an error message lights up in the counter display section, and the cassette tape is automatically ejected.

Keep the power on and wait until the error message is cleared.

Maintenance

Before performing any maintenance work, set the power switch to the OFF position and disconnect the power cable from the AC outlet making sure that you take hold of the molded part of the power plug.

Use a soft cloth to clean the cabinet. In order to get rid of stubborn dirt, dilute some neutral kitchen detergent with water, dip a cloth into the solution, wring it out well, and wipe away the dirt. Then wipe off any moisture which remains using a dry cloth.

Do not use paint thinners or benzine for cleaning purposes.
