the instructions mentioned in this manual and marked on the product.

1. Please read this manual before you

operate your projector. Save it for future

reference.

2. Do not look straight at the projector

lens during operation. The intense light

beam may damage your eyes.

3. Refer servicing to qualied service

personnel.

4. In some countries, the line voltage is

NOT stable. This projector is designed

to operate safely within a mains voltage

between 100 to 240 volts AC, but could

fail if power cuts or surges of ±10 volts

occur. In areas where the mains

voltage may uctuate or cut out, it is

recommended that you connect your

projector through a power stabilizer,

surge protector or uninterruptible

power supply (UPS).

5. Do not block the projection lens with

any objects when the projector is under

operation as this could cause the objects

to become heated and deformed or even

cause a re. To temporarily turn off the

light source, press ECO BLANK on the

images for wall mount installation.

Use only BenQ's Wall Mount Kit for

mounting the projector and ensure it is

securely installed.

Wall mounting the projector

We want you to have a pleasant experience

using your BenQ projector, so we need to bring

this safety matter to your attention to prevent

possible damage to person and property.

If you intend to mount your projector on the

wall, we strongly recommend that you use a

proper tting BenQ projector wall mount kit and

that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector wall

mount kit, there is a safety risk that the projector

may fall from the wall due to an improper

attachment through the use of the wrong gauge

or length screws.

You can purchase a BenQ projector wall mount

kit from the place you purchased your BenQ

projector. BenQ recommends that you also

purchase a separate Kensington lock compatible

security cable and attach it securely to both the

Kensington lock slot on the projector and the

base of the wall mount bracket. This will perform

the secondary role of restraining the projector

should its attachment to the mounting bracket

become loose.

There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that

if you intend to permanently install the projector, you should physically test the projection size and distance

using the actual projector before you permanently install it, so as to make allowance for this projector's

optical characteristics. This will help you determine the exact mounting position so that it best suits your

installation location..

It is recommended to adjust focus 15 minutes after powering on due to the slight shifting of the lens from

temperature changing.

Positioning your projector

Mounting the projector

If you intend to mount your projector, we strongly recommend that you use a proper tting BenQ

projector mounting kit and that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may

fall down due to an improper attachment through the use of the wrong gauge or length screws.

Before mounting the projector

• Use BenQ Projector Wall Mounting Kit come with the package. Please refer to the User manual

in the box of wall mount kit for installation details.

• BenQ recommends that you also purchase a separate Kensington lock compatible security cable

and attach it securely to both the Kensington lock slot on the projector and the base of the

mounting bracket. This will perform the secondary role of restraining the projector should its

attachment to the mounting bracket become loose.

• Ask your dealer to install the projector for you. Installing the projector on your own may cause

it to fall and result in injury.

• Take necessary procedures to prevent the projector from falling off such as during an

earthquake.

• The warranty doesn’t cover any product damage caused by mounting the projector with a non-

BenQ brand projector mounting kit.

• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater

is used, the temperature around the ceiling may be higher than expected.

• Read the user manual for the mounting kit about the range of torque. Tightening with torque

exceeding the recommended range may cause damage to the projector and subsequently falling

off.

• Make sure the power outlet is at an accessible height so that you can easily shut down the

projector.
