Precautions for use
Intended use of the product
The product is intended to project still/moving image signals from video equipment and computers onto a screen.
Cautions when transporting
f When transporting the projector, handle it with care and avoid excessive vibration and impacts. Doing so may
damage the internal parts and result in malfunctions.
f Do not transport the projector with the adjustable foot extended. Doing so may damage the adjustable foot.
f (Only for PT-LW376, PT-LW336, PT-LB426, PT-LB386 and PT-LB356)
Do not move or transport the projector with the wireless module (Model No.: AJ-WM50 / ET-WML100) of the
optional accessories attached. Doing so may damage the wireless module.
Cautions when installing
rDo not set up the projector outdoors.
The projector is designed for indoor use only.
rDo not set up the projector in the following locations.
f Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal
components or malfunction.
f Locations near the sea or areas aected by corrosive gas: Corrosion may damage internal components or
cause the projector to malfunction.
f Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may uctuate in rare
cases due to the heated air from the exhaust vent or the hot or cooled air. Make sure 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.
f Places with sharp temperature uctuations such as near lights (studio lamps): Doing so may shorten the life of
the lamp, or result in deformation of the outer case due to heat, which may cause malfunctions.
Follow the operating environment temperature of the projector.
f Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
rAsk a qualied technician or your dealer for the installation work such as installing to
a ceiling.
To ensure projector performance and safety, ask a qualied technician or your dealer when installing to a ceiling
or in a high place.
rFocus adjustment
The projection lens is thermally aected by the light from the light source, making the focus unstable in the period
just after switching on the power. It is recommended that the images be projected continuously for at least 30
minutes before the focus is adjusted.
rDo not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
r Do not use the projector in a location that the ambient temperature exceeds 40 °C (104 °F).
Using the projector in a location that the altitude is too high or the ambient temperature is too high may shorten
the life of the components or result in malfunctions.
rDo not tilt the projector or place it on its side.
Do not tilt the projector body more than approximately ±30 degrees vertically or ±15 degrees horizontally. Over
tilting may result in shortening the life of the components.
For PT-LB306, keystone correction in the horizontal direction is not supported. If the projector is tilted horizontally,
horizontal trapezoidal distortion cannot be corrected.
