7-2. Cleaning

Cleaning the Cabinet

1. Turn off the projector before cleaning.

2. Clean the cabinet periodically with a damp cloth. If heavily

soiled, use a mild detergent. Never use strong detergents or

solvents such as alcohol or thinner.

* The projector has a sensor which detects an object in front of

the largest mirror or in the light path. If the sensor detects any

object, the projector will not turn on. If this happens while the

projector is turned on, the image is muted. In either case the

STATUS indicator flashes in red.

* The projector has a temperature sensor which detects exces-

sive heat. If the sensor detects heat in the bottom of the mir-

ror or in the light path, the projector will not turn on. If this

happens while the projector is turned on, the projector will

turn off (the idle mode). In either case the STATUS indicator

flashes in red.

Handling and Care of Mirror surface

If the projector is not to be used for an extended period of time,

close the mirror cover.

This will protect the projector against dropping an object or gath-

ering dust.

Consult with your dealer when using the projector exposed to

smoke or dust.

Long-term exposure to sulfide can corrode the mirror surface.

Cleaning the mirror face

Keep finger prints off the mirror surface. Do not scratch the mir-

ror surface with a hard or pointed object.

Leaving a defect in the mirror surface might cause an unwanted

shadow and poor picture quality.

If the mirror surface is soiled with fingers prints or dust, wipe

them off with the supplied cleaning cloth.

When removing sandy dust, use a blower to blow off dust or

brush it off softly and wipe the mirror surface with the supplied

cleaning cloth.

Do not blow your breath against the mirror surface, which can

accidentally put your saliva on the mirror surface.

Leaving foreign grease stains, oil-smudged finger prints or salt

on the mirror surface can cause damage to the reflective coat-

ing on the mirror surface.

Use only the supplied cleaning cloth to clean the mirror surface.

Failure to do so can mar the mirror surface.

Do not force the cleaning cloth against the mirror surface or ap-

ply excessively strong pressure against it. Do not scratch it with

your nails while wiping off.

Never use strong detergents or solvents such as thinner or ben-

zene. Doing so can corrode the reflective coating on the mirror

surface.

If heavily soiled and wiping with the cleaning cloth will not work,

use absolute alcohol. After the mirror surface is dried, wipe it

with the cleaning cloth again.

If the supplied cleaning cloth is soiled, wash it. It is recommended

you wash it every after two to three uses.

Do not allow long-term close contact with rubber or vinyl prod-

ucts because this could cause the reflective coating of the mir-

ror surface to deteriorate.

Do not spray volatile substances such as insect repellent on the

mirror surface.
