Video Head Cleaning

This unit is equipped with an auto head cleaning function which automatically reduces the amount of dirt on the video heads. However, in order to maximize the unit’s reliability, 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 our service companies or with your dealer.

Condensation

Condensation is formed according to the same principle by which droplets of water form on the window panes of heated rooms. It forms in the unit when the unit or tape is moved to a location with a significant difference in temperature or humidity. It also forms when the unit has been moved:

OTo a very humid location filled with steam or a room immediately after it has been heated up.

OSuddenly from an air-conditioned environment to a place with high temperature and humidity

levels.

When moving the unit to these types of locations, do not turn on the power immediately but leave the unit standing and wait for about 10 minutes. If condensation has formed inside the unit, an error message (– d –) lights up on the counter display, and the cassette tape is automatically ejected.

Leave the power on, and wait until the error message is cleared.

Maintenance

Before proceeding with maintenance, set the power switch to the OFF position, and disconnect the unit from the power outlet: always remember to take hold of the molded part of the power plug when doing this.

Use a soft cloth to clean the cabinet. In the case of stubborn dirt, dilute some kitchen detergent, soak a cloth in the solution, wring it out well, and now use it for cleaning. After wiping up the dirt, remove any remaining moisture with a dry cloth.

Do not use paint thinners or benzine.
