1. Preparations for Using the Projector

This chapter explains the names and functions of the different parts of the projector and remote control, and how to use them. It also explains how to position the projector and how to connect it to other equipment.

Precautions for Using the Projector

•If metal objects, or water or other fluids fall inside this machine, you must turn off its power immediately. After turning off the power, be sure to disconnect the power cord plug from the wall outlet. Then contact your service representative and report the problem. Do not use the machine. Doing so could result in fire or electric shock.

•Do not use any power sources other than those that match the specifications shown in this manual. Doing so could result in fire or electric shock.

•The supplied power cord is for use with this machine only. Do not use it with other appliances. Doing so could result in fire or electric shock.

•It is dangerous to handle the power cord plug with wet hands. Doing so could result in electric shock.

•Do not place the power cord and connection cable in front of the lens or exhaust vents when the product is turned on. Doing so may result in fire.

•Be sure to locate the machine as close as possible to a wall outlet. This will allow easy disconnection of the power cord in the event of an emergency.

•Do not look into the projection window or vent when the machine is on. The bright light may damage your eyes. Be especially careful in an environment with children.

•Do not use flammable sprays or solvents in the vicinity of this machine. Also, avoid placing these items in the vicinity of this machine. Doing so could result in fire or electric shock.

•Do not place low heat resistant material near the exhaust vents. Hot air may come from the exhaust vents, resulting in damage to the machine or an accident.

•Do not place the power cord and connection cable in a way that might cause someone to trip and fall. The machine might fall over and cause an injury.

11

1. Preparations for Using the Projector

•Push the power plug all the way into the power outlet. Do not use a power outlet with a loose connection. Doing so may result in heat buildup. Plug the power cord in the correct direction

into the base. If they are not plugged in correctly, it could result in smoke, fire, or electric shock.

•When disconnecting the power cord from the wall outlet, always pull the plug, not the cord. Pulling the cord can damage the power cord. Use of damaged power cords could result in fire or electric shock.

•Do not block the projection light when it is on. If you do so, the part that is blocking the projection light may get quite hot and deform, deteriorate or cause a burn or fire. The reflected light may make the projection window hot and cause a machine failure. To temporarily suspend projection, select the AV mute function. To suspend longer, turn off the machine.

•Do not increase the volume unless you are listening while increasing the volume. Also, lower the volume before turning off the power, because a loud sound may be emitted when the power is turned on and cause hearing damage.
