Chapter 1 Preparation — Precautions for use

Precautions for use

Cautions when transporting

ffIf you purchased the projector with the standard zoom lens, remove the lens cushion before use, and store it for the future

use. When transporting the projector, move the lens to the home position and attach the lens cushion and the lens cover.

If you purchased the projector with the lens sold separately, remove the lens hole cover before use, and store it for the future use. When transporting the projector, move the projection lens to the home position, remove the Projection Lens, and then attach the lens hole cover.

For the steps to move the lens to the home position, refer to “Moving the lens to the home position” (x page 52).

ffWhen transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts. They may damage the internal components and result in malfunctions.

ffDo not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.

Cautions when installing

rrDo not set up the projector outdoors.

The projector is designed for indoor use only.

rrDo not set up the projector in the following locations.

ffPlaces where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal components or malfunction.

ffNear the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases due to the heated air from the air exhaust port 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.

ffPlaces with sharp temperature fluctuations 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.

The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F) when using it at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 40 °C (104 °F) when using it at high altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level).

ffNear high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.

rrBe sure to ask a specialized technician or your dealer when installing the projector on a ceiling.

The optional Ceiling Mount Bracket is required.

Model No.: ET‑PKE200H (for High Ceilings), ET‑PKE200S (for Low Ceilings), ET‑PKE200B (Projector Mount Base)

rrAsk a qualified technician or your dealer to install the cable wiring for DIGITAL LINK connection.

Image and sound may be disrupted if cable transmission characteristics cannot be obtained due to inadequate installation.

rrThe projector may not work properly due to strong radio wave from the broadcast station or the radio.

If there is any facility or equipment, which outputs strong radio wave, near the installation location, install the projector at a location sufficiently far from the source of the radio wave. Or, wrap the LAN cable connected to the <DIGITAL LINK/LAN> terminal by using a piece of metal foil or a metal pipe, of which is grounded at both ends.

rProjection Lens

Be sure to use the standard zoom lens supplied with the projector (PT‑EZ770Z, PT‑EW730Z, PT‑EX800Z only) or the specified Projection Lens (optional). The standard zoom lens supplied with PT‑EZ570 series, PT‑EW630 series, PT‑EW530 series, PT‑EX600 series, PT‑EX500 series is different from the lens of this projector. Using it may result in malfunction or damage. Do not use it.
