Ceiling 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 ceiling, we strongly recommend that you use a proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the projector may fall from the ceiling due to an improper attachment through the use of the wrong gauge or length screws.

You can purchase a BenQ projector ceiling 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 ceiling mount bracket. This will perform the secondary role of restraining the projector should its attachment to the mounting bracket become loose.

manufacturer's instructions.

• Never throw a battery into a fire. There may be danger of an explosion.

• If the battery is dead or if you will not be using the remote control for a long time, remove the battery to

prevent damage to the remote control from possible battery leakage.

Introduction12

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1. Front Table

Select this location with the projector placed on the table in front of the screen. This is the most common way to position the projector for quick setup and portability.

2. Front Ceiling

Select this location with the projector suspended upside-down from the ceiling in front of the screen.

Purchase the BenQ Projector Ceiling Mount Kit from your dealer to mount your projector on the ceiling.

Set Front Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

3. Rear Ceiling

Select this location with the projector suspended upside-down from the ceiling behind the screen.

Note that a special rear projection screen and the BenQ Projector Ceiling Mount Kit are required for this installation location.

Set Rear Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

4. Rear Table

Select this location with the projector placed on the table behind the screen.

Note that a special rear projection screen is required.

Set Rear Table in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment.

Positioning your projector 13

Obtaining a preferred projected image size

(a)

(b)

Center of lens

Screen

(c)

The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size.

For example, if you are using an 120-inch screen, the recommended projection distance is 1481 mm and the vertical offset is 274 mm.

If your measured projection distance is 2.5 m (2500 mm), the closest match in the "(b)

Distance from screen" column is 2469 mm. Looking across this row shows that a 200''

(about 5.1 m) screen is required.

Projection dimensions

Refer to "Dimensions" on page 53 for the center of lens dimensions of this projector before calculating the appropriate position.

Operation

Starting up the projector

1. Plug the power cord into the projector and into a

power outlet. Turn on the power outlet switch (where fitted). Check that the POWER indicator light on the projector lights orange after power has been applied.

Please use the original accessories (e.g. power cord) only with the device to avoid possible dangers such as electric shock and fire.

2. Press POWER on the projector or ON on the remote control to start the

projector. As soon as the lamp lights up, a "Power On To n e " will be heard. The POWER indicator light flashes green and stays green when the projector is on.

The start up procedure takes about 30 seconds. In the later stage of start up, a startup logo is projected.

(If necessary) Rotate the focus ring to adjust the image clearness.

To turn off the ring tone, see "Turning off the Power On/Off Ring Tone" on page 33 for details.

If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 seconds before energizing the lamp.

3. If the projector is activated for the first time,

select your OSD language following the onscreen instructions.

4. If you are prompted for a password, press the

arrow keys to enter a six-digit password. See

"Utilizing the password function" on page 21 for

details.

5. Switch all of the connected equipment on.

6. The projector will start to search for input

signals. The current input signal being scanned displays in the upper left corner of the screen. If the projector doesn't detect a valid signal, the message “No Signal” will continue displaying until an input signal is found.

You can also press SOURCE on the projector or remote control to select your desired input signal. See "Switching input signal" on page 24 for details.

If the frequency/resolution of the input signal exceeds the projector's operating range, you will see the message “Out of Range” displayed on a blank screen. Please change to an input signal which is compatible with the projector's resolution or set the input signal to a lower setting. See "Timing chart" on page 56 for details.

Operation 17

Adjusting the projected image

Do not look into the lens while the lamp is on. The strong light from the lamp may cause damage to your eyes.

Be careful when you press the quickrelease button as it is close to the exhaust vent where hot air comes from.

Adjusting the projection angle

The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These adjusters change the image height and projection angle. To adjust the projector:

1. Press the quick-release button and lift the

front of the projector. Once the image is positioned where you want it, release the quick-release button to lock the foot in position.

2. Screw the rear adjuster foot to fine-tune the

horizontal angle.

To retract the foot, hold up the projector while pressing the quick-release button, then slowly lower the projector. Screw the rear adjuster foot in a reverse direction.

If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected image becomes trapezoidal. To correct this situation, see "Switching

input signal" on page 24 for details.

Auto-adjusting the image

In some cases, you may need to optimize the picture quality. To do this, press Auto on the projector or remote control. Within 3 seconds, the built-in Intelligent Auto Adjustment function will re-adjust the values of Frequency and Clock to provide the best picture quality.

The current source information will be displayed in the corner of the screen for 3 seconds.

This function is only available when PC signal (analog RGB) is selected.

Fine-tuning the image clarity

Sharpen the image by rotating the focus ring.
