Care of the projector

Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens clean and clean or replace the air filter. Never remove any parts of the projector except the lamp or the air filter. Contact your dealer or local BenQ Customer Service Centre if the projector fails to operate as expected.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface. Before you attempt to clean the lens, turn the projector off, unplug the power cable, and leave it several minutes to cool completely.

1.Use a canister of compressed air to remove dust. (Available from building hardware or photographic suppliers.)

2.If there is stubborn dirt or smudge marks, use a proper photographic lens brush or moisten a clean soft lens cloth with lens cleaner to gently wipe the lens surface.

Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can damage the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution. Do not attempt to clean the lens whilst the projector is switched on or is still hot from previous use.

Storing the projector

If you need to store the projector for an extended time, please:

1.Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please refer to the Spec. page in this manual or consult your dealer about the range.

2.Retract the adjuster feet.

3.Remove the batteries from the remote control.

4.Pack the projector in its original packing or equivalent.

Transporting the projector

It is recommended that you ship the projector with its original packing or equivalent. When you carry the projector yourself, please use a soft carry case.

Cleaning and replacing the dust filter

It is necessary to clean the dust filter periodically every 1000 hours use. You can use the Advanced Setup > Dust Filter > Dust Filter Hours menu or the Information menu to check how long the filter has been used. If the filter is not cleaned, it can become clogged with dust and prevent proper ventilation. This can cause overheating and a malfunction of the projector.

Should the projector filter become seriously clogged with dust,
