MAINTENANCE

ENGLISH

This unit requires very little attention, but you will be able to extend the life of the unit if you follow the instructions below.

To clean the head

Clean the head after every 10 hours of use using a wet-type head cleaning tape (available at an audio store).

When the head becomes dirty, you may realize the following symptoms:

Sound quality is reduced.

Sound level decreases.

Sound drops out.

Do not play dirty or dusty tapes.

Do not touch the highly-polished head with any metallic or magnetic tools.

CAUTION:

Do not play the cassettes with peeling labels; otherwise, they can damage the unit.

Tighten tapes to remove slack since loose tape may become entangled with the mechanism.

Do not leave a cassette in the cassette compartment after use, as the tape may become slack.

The function below is also provided to ensure the

longer life of this unit.

Ignition key-off release/Ignition key-on play

Turning off the ignition key with a cassette in the compartment automatically releases the tape from the unit’s tapehead.

Turning on the ignition key with a cassette in the compartment starts playback automatically if you turned off the ignition during tape play.

To keep the tape clean

Always store the cassettes in their storage cases after use.

Do not store cassettes in the following places:

Subject to direct sunlight

With high humidity

At extremely hot temperatures
