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.

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 nonBenQ 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.

Playing sound through the projector

You can make use of the projector speaker in your presentations, and also connect separate amplified speakers to the AUDIO OUT socket of the projector.

If you have a separate sound system, you will most likely want to connect the audio output of your Video source device to that sound system, instead of to the audio projector.

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus.

The table below describes the connection methods for different devices, and where the sound is from.

colors consisted of more proportions of

its two adjacent colors. Please refer to the

illustration for how the colors relate to

each other.

White

For example, if you select Red and set its

range at 0, only pure red in the projected

picture will be selected. Increasing its range

will include red close to yellow and red

close to magenta.

· Saturation: Adjusts the values to your preference. Every adjustment made will reflect to the image immediately. For example, if you select Red
and set its value at 0, only the saturation of pure red will be affected.

Saturation is the amount of that color in a video picture. Lower settings produce less saturated colors; a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic.

We recommend you use the High Altitude Mode when your environment is between 1500 m ­3000 m above sea level, and ambient temperature is between 0°C­30°C.
Operation under “High Altitude Mode” may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling and performance.
If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitude mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such a condition.
Selects a baud rate that is identical with your computer’s so that you can connect the projector using a suitable RS-232 cable and update or download the projector’s firmware. This function is intended for qualified service personnel. · Top Left: To correct the top left corner.
