IMPORTANT SAFETY INFORMATION

Important Safeguards

These safety instructions are to ensure the long life of the unit and to prevent fire and shock. Please read them carefully and heed all warnings.

Installation

•For best results, use the unit in a darkened room.

•Place the unit on a flat, level surface in a dry area away from dust and moisture.

•Do not place the unit in direct sunlight, near heaters or heat radiating appliances.

•Exposure to direct sunlight, smoke or steam can harm internal components.

•Handle the unit carefully. Dropping or jarring can damage internal components.

•Do not place heavy objects on top of the unit.

Power Supply

•The unit is designed to operate on a power supply of 100 - 240 V 50/60 Hz AC. Ensure that your power supply fits these requirements before attempting to use the unit.

•Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire.

•Disconnect the power cable (main’s lead) from the power outlet after using the unit.

Before disconnecting the power cable, make sure that the STANDBY indicator lights in amber (not blinking or in green).

Cleaning

•Disconnect the power cable (main’s lead) from the unit.

•Clean the cabinet of the unit periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong detergents or solvents such as alcohol or thinner.

•Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.

•Clean the ventilation slots and speaker grills on the unit periodically using a vacuum cleaner. If accumulated dust blocks the ventilation slots, the unit will overheat, which may cause the unit to malfunction.

Use a soft brush attachment when using the vacuum cleaner. Do not use a hard attachment, such as a crevice tool, to prevent the damage to the unit.

Lamp Replacement

•Be sure to replace the lamp when the Status indicator comes on. If you continue to use the lamp after 1500 hours of usage, the lamp will turn off.

Fire and Shock Precautions

•Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the buildup of heat inside the unit. Allow at least 10 cm (3 inches) of space between the unit and walls.

•Prevent foreign objects such as paper clips and bits of paper from falling into the unit. Do not attempt to retrieve any objects that fell into the unit. Do not insert any metal objects such as a wire or screwdriver into the unit. If something should fall into the unit, immediately disconnect the power cable from the unit and have the object removed by a qualified PLUS service person.

•Do not place any liquids on top of the unit.

Carrying around

When carrying the unit around, please use the carrying case that comes with it and, to protect the lens from scratches, always shut the sliding lens cap. Also, do not subject the unit to strong mechanical shock.

Remove the wireless LAN card.

CAUTION – HOT!

The area around the exhaust vents is hot during and immediately after image projection. To avoid burns, keep your hands away from this area.

Wait until the exhaust vents area cools off before touching it.

Do not look into the lens while the unit is on. Serious damage to your eyes could result.
