Installing the Projector

Precautions for Installation

Please read the following properly when installing the projector.

Installation Environment

Please do not install or use this projector in the follow- ing places. The projector is a precision device and do- ing so could cause a fire or malfunction.

Where there is water, humidity or dust.

Where the projector may be subjected to oil, smoke or cigarette smoke.

On a soft surface such as a carpet or cushion.

Where the projector may be subjected to direct sunlight.

Where temperature is high or low.

Allowable operation temperature range

: +5°C to +35°C

Allowable relative humidity range

: 20% to 80%

 

(no condensa-

 

tion)

Allowable storage temperature range

: –10°C to +60°C

Any room in which there is smoke and grease.

Even where smoke and grease levels are minimal, pro- longed exposure will affect the projector. The projector emits heat and optical components are cooled down by taking in large amount of air. The optical path being soiled by grease/dirt can cause images to become dark and the color projection to deteriorate. After soiling, remov- ing grease/dirt totally from the optical parts is not possi- ble.

Precaution for Usage

This projector uses a light-source lamp which reaches high temperatures when projecting.

Please DO NOT use it in the following ways as doing so may result in fire or malfunction.

Projecting images while the projector is on its side.

Projecting images outside the specified angle.

Do not use the projector while it is set more than ±5° horizontally (left/right), or more than ±25° vertically (up/ down). This could cause color variation or shorten the lamp life.

Use while blocking the exhaust vents.

Do not use a cover which may enclose the projector air-tight or block the exhaust vents. Allow sufficient space around the projector. When the projector is en- closed in a space of the following dimensions, use an air conditioner so that internal and external tempera- tures are the same.

Adjusting the Inclination of the Projector

The vertical angle and leveling of the projector can be adjusted with the adjustable feet at the bottom of the projector.

Vertical angle adjustment range
