Cautions when installing
■ After installing the projection lens, make sure to attach the projection
lens cover.
z
If the cover is not attached, dust will be accumulated inside and can cause a trouble.
■ Do not set up the projector outdoors.
z
The projector is designed for indoor use only.
■ Do not use under the following conditions.
z
Places where vibration and impacts occur such as in a car or vehicle: Doing so may damage the internal
parts and result in malfunctions.
z
Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may uctuate due to the hot
air from the air exhaust port or the heated or cooled air from the air conditioner. Take care so that the exhaust from
the projector or other equipment, or the air from the air conditioner does not blow toward the front of the projector.
z
Near lights (studio lamps, etc.) where temperature changes greatly (Operating environment (
page 105)):
Doing so may shorten the life of the lamp or result in deformation of the outer case and malfunctions.
z
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
z
Place where there is a high-power laser equipment: It may cause malfunction in DLP chips when the laser
beam enters the lens.
■ Be sure to ask a specialized technician when installing the product to a ceiling.
If the product is to be installed hanging from the ceiling, purchase an optional Ceiling Mount Attachment (For
high ceilings: Model No. ET-PKD56H, For low ceilings: Model No. ET-PKD55S). Please call a specialized
technician or contact an Authorized Service Center for installation.
■ Lens Focus
Do not adjust the lens focus in the initial period after switching the projector on. The high clarity projection
lens is thermally affected by the light from the light source, making the focus unstable in the period just after
switching on. Please allow a warm-up time of at least 30 minutes before adjusting the lens focus.

projector at elevations of 1 400 m (4 593 ft) or higher and lower than
2 700 m (8 858 ft) above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.
■ Make sure to set [HIGH ALTITUDE MODE] to [OFF] when using the
projector at elevations lower than 1 400 m (4 593 ft) above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.
■ Do not install the projector at elevations of 2 700 m (8 858 ft) or higher
above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.
