Introduction12

Remote control effective range

• Operating the projector from the front

• Operating the projector from the top

Infra-Red (IR) remote control sensors are located on the front and the top of the projector. The remote control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensors to function correctly. The distance between the remote control and the sensors should not exceed 8 meters (~ 26 feet).

Make sure that there are no obstacles between the remote control and the IR sensors on the projector that might obstruct the infra-red beam.

Replacing the remote control batteries

1. To open the battery cover, turn the remote control over to view its back, push on the finger grip on the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off.

2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative.

3. Refit the cover by aligning it with the base and sliding it back down into position. Stop when it clicks into place.

• Avoid leaving the remote control and batteries in an excessive heat or humid environment

like the kitchen, bathroom, sauna, sunroom or in a closed car.

• Replace only with the same or equivalent type recommended by the battery manufacturer.

• Dispose of the used batteries according to the manufacturer's instructions and local

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

period of time, remove the batteries to avoid damage to the remote control from possible battery leakage.

Introduction 13

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.

For example, if you are using a 120-inch screen, the recommended projection distance is 4457 mm and the vertical offset is 91 mm - 274 mm.

If your measured projection distance is 5.0 m (5000 mm), the closest match in the "Distance

from screen (mm)" column is 4457 mm or 5571 mm. Looking across this row shows that a

120'' (about 3.0 m) or 150'' (about 3.8 m) screen is required.

There is 3% 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 in situ 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.

The lens shift control provides flexibility for installing your projector. It allows the projector to be positioned off the center of the screen.

The lens shift is expressed as a percentage of the projected image height or width. It is measured as an offset from the projected image’s vertical or horizontal center. You can use a screwdriver to shift the projection lens within the allowable range depending on your desired image position.

To shift the projection lens, open the flap on the side of the projector to expose an access (a deep hole) to the lens shift device. Insert a screwdriver to touch the device, and then rotate the screwdriver clockwise or counterclockwise until the screen is positioned where you want it.

• When the screen position is fixed

• When the projector position is fixed

• To avoid causing damage to the lens shift device, rotate the screw driver slowly and

gently.

• Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that

the image distortion is produced, see "Correcting keystone" on page 23 for details.

Best

Better

Good

Normal

Connecting audio

The projector has two built-in mono speakers which are designed to provide basic audio functionality accompanying data presentations for business purposes only. They are not designed for, nor intended for stereo audio reproduction use as might be expected in home theater or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speakers.

The built-in speakers will be muted when the AUDIO OUT jack is connected.

• In the unlikely event that you connect the projector to a DVD player via the projector’s HDMI input and the projected picture displays wrong colors, please change the color space to YUV. See "Changing Color Space" on page 28 for details.

• The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See "Connecting audio" on page 18 for details.

• If the selected video image is not displayed after the projector is turned on and the correct video source has been selected, check that the video source device is turned on and operating correctly. Also check that the signal cables have been connected correctly.

Connection18

Playing sound through the projector

You can make use of the projector (mixed mono) 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 mono audio projector.

You can also use a microphone to output the sound through the projector speaker.

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 63 for details.

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

Device

Audio input port

The projector can

play the sound

from...

Audio output port

The selected input signal determines which sound will be played by the projector speaker, and which sound will be output from the projector when AUDIO OUT is connected. If you select the COMPUTER 1/YPbPr 1 signal, the projector can play the sound received from AUDIO IN 1/MIC. If you select the COMPUTER 2/YPbPr 2 signal, the projector can play the sound received from AUDIO IN 2/MIC.

The projector can play sound if the connected RJ45 cable or USB cable carries audio signal. There is no need to connect the audio cable when the USB Display or Network Display source is selected.

About the microphone input

• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the projector.

• You can use a wireless microphone as long as a wireless module is attached to the projector’s microphone input jack and it works well with the associated devices. To ensure a quality use of the wireless microphone, it is recommended that your microphone conforms to the specifications listed in the table below.

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 Tone" 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 37 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 25 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.

Yo u ca n a ls o p re ss SOURCE on the projector or remote control to select your desired input signal. See "Switching input signal" on page 28 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 76 for details.

Operation 21

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 quick-release button as it is close to the exhaust vent where hot air comes from.

Adjusting the projection angle

The projector is equipped 4 adjuster feet. These adjusters change the image height and projection angle. To adjust the projector:

Screw the rear adjuster feet to fine-tune the horizontal angle.

To retract the feet, screw the adjuster feet 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 "Correcting keystone" on page 23 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 size and clarity

1. Adjust the projected image to the size that you need using the zoom ring.

Operation22

2. Sharpen the image by rotating the focus ring.

Correcting keystone

Press /.

Keystoning refers to the situation where the projected image is noticeably wider at either the top or bottom. It occurs when the projector is not perpendicular to the screen.

To correct this, besides adjusting the height of the projector, if you want the projector to automatically correct image keystoning, be sure the Auto Keystone function in the DISPLAY menu is On.
