When warning indication is shown by the blinking indicators:

The warning status will be notified by the combination lighting of the projector’s indicators.

For the warning contents and the action to be taken, refer to “Warning Indication” on page 63.

Maintenance

Stains on the cabinet

These should be wiped off with a soft cloth. If the cabinet is heavily stained, wipe it with a cloth soaked in water-diluted neutral detergent and wring well, then wipe clean with a dry cloth.

Since the cabinet may deteriorate in quality, become damaged, or show paint peeled, note the following:

Do not wipe with rough cloth.

Do not wipe vigorously.

Do not wipe with thinner or benzene.

Do not apply any volatile substance such as insecticides.

Do not allow any rubber or vinyl article to remain in contact with the cabinet for a long time.

Stains on the lens

These should be cleaned off with commercially available lens blowers or lens cleaning paper (for cleaning glasses and cameras).

Do not use liquid cleaning agents. This could cause the surface coating to be removed. Do not rub, scratch or hit the lens as its surface is prone to damage.
