12 Positioning your projector

Offset

(mm)

For example, if you are using a 120-inch screen, the recommended projection distance in the "Average" column is 3436 mm.

If your measured projection distance is 3700 mm, the closest match in the "Average" column is 3723 mm. Looking across this row shows that a 130'' (about 3.3 m) screen is required.

To optimize your projection quality, we suggest to do the projection within non-gray area.

All measurements are approximate and may vary from the actual sizes. 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.

Mounting the projector

If you intend to mount your projector, we strongly recommend that you use a proper fitting 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

• Purchase a BenQ projector mounting 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 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.

Adjusting the projected image

Adjusting the projection angle

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. You can adjust the adjuster feet to fine-tune the horizontal angle.

To retract the feet, screw the adjuster feet in a reverse direction.

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

65.89

Auto-adjusting the image

In some cases, you may need to optimize the picture quality. To do this, press AUTO. 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.

Quick Cooling

High Altitude Mode

Select On enables the function and projector cooling time will be shortened from a normal 90-second duration to approximately 15 seconds.

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°C–30°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.

Getting to know the lamp hour

When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows:

1. Light Usage Time = (x+y+z+a) hours, if:

Time used in Normal mode = x hours

Time used in Economic mode = y hours

Time used in SmartEco mode = z hours

Time used in LampSave mode = a hours

2. Equivalent Lamp Hour = hours

, if

X= lamp life spec of Normal mode

Y= lamp life spec of Economic mode

Z= lamp life spec of SmartEco mode

A= lamp life spec of LampSave mode

A’ is the longest lamp life spec among X, Y, Z, A

When you calculate Equivalent Light Usage hour manually, it will probably have deviation from the value shown in OSD menu since projector system calculates time used for each light mode in “Minutes” then rounds down to an integer in hours shown in OSD.

For time used in each light mode shown in OSD menu:

• Time used is accumulated and rounded down to an integer in hours.

• When time used is less than 1 hour, it shows 0 hours.

To obtain the lamp hour information:

1. Go to Advanced Menu - System Setup : Advanced > Light Settings and press OK. The Light Settings page appears.

2. Press to select Light Usage Time and press OK. The Light Usage Time information is displayed.

You can also get the Light Usage Time information on the Information menu.

Timing of replacing the lamp

When the LIGHT indicator lights up or a message appears suggesting it is time to replace the lamp, please consult your dealer or go to http://www.BenQ.com before installing a new lamp. An old lamp may cause a malfunction in the projector and in some instances the light may explode.

• The apparent brightness of the projected image will vary depending on the ambient lighting conditions, selected input signal contrast/brightness settings, and is directly proportional to projection distance.

• The lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This is normal and expected behavior.

• The LIGHT indicator light and TEMPerature warning light will light up if the lamp becomes too hot. Turn the power off and let the projector cool for 45 minutes. If the Light or Temp indicator still lights up after turning the power back on, please contact your dealer. See Indicators on page 46.

The following Lamp warning displays will remind you to change the lamp.

Install a new lamp for optimal performance. Press OK to dismiss the message.

It is strongly recommended that you replace the lamp at this age. The lamp is a consumable item. The lamp brightness diminishes with use. This is normal lamp behavior. You can replace the lamp whenever you notice that the brightness level has significantly diminished. Press

Replacing the lamp (FOR SERVICE PERSONNEL ONLY)

• To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp.

• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the lamp.

• To reduce the risk of injuries to fingers and damage to internal components, use caution when removing lamp glass that has shattered into sharp pieces.

• To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not touch the empty lamp compartment when the lamp is removed.

• This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a proper manner.

• To assure optimal performance from the projector, it is recommended that you purchase a qualified projector lamp for lamp replacement.

• If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes caused by fractured lamp.

• Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety glasses, goggles or face shield and wear protective clothing such as gloves.

1. Turn the power off and disconnect the projector from the power outlet. If the lamp is hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled.

2. Loosen the screw(s) that secure the lamp cover on the side of the projector until the lamp cover loosens.

3. Remove the lamp cover from the projector.

• Do not turn the power on with the lamp cover open.
