Notes on Installation and Usage

Unsuitable Installation

Do not install the projector in the following situations. These installations may cause a malfunction or damage to the projector.

Poorly ventilated

•Allow adequate air circulation to prevent internal heat build-up. Do not place the unit on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies) that may block the ventilation holes. When the internal heat builds up due to the block-up, the temperature sensor will function with the message “High temp.! Lamp off in 1 min.” The power will be turned off automatically after one minute.

•Leave space of more than 30 cm (11 7/8 inches) around the unit.

•Be careful that the ventilation holes may inhale tininess such as a piece of paper.

Highly heated and humid

•Avoid installing the unit in a location where the temperature or humidity is very high, or temperature is very low.

•To avoid moisture condensation, do not install the unit in a location where the temperature may rise rapidly.

Subject to direct cool or warm air from an air-conditioner

Overview

Installing in such a location may cause malfunction of the unit due to moisture condensation or rise in temperature.

Near a heat or smoke sensor

Malfunction of the sensor may be caused.

Very dusty, extremely smoky

Avoid installing the unit in a very dusty or extremely smoky environment. Otherwise, the air filter will become obstructed, and this may cause a malfunction of the unit or damage it. Dust preventing the air passing through the filter may cause a rise in the internal temperature of the unit. Clean the filter periodically.
