For example, if you are using a 120-inch screen, the recommended projection distance is 3454mm .

If your measured projection distance is 5000 mm, the closest match in the "Distance from screen (mm)" column is 4893 mm. Looking across this row shows that a 170" (about 4.3 m) screen is required.

• 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.
• To optimize your projection quality, we suggest doing the projection by following the values in the non-gray cells.
• The values in the gray cells are for reference only.

Shifting the projection lens

- Please stop turning the adjustment knob when you hear a clicking sound indicating the knob has reached its limit. Over-turning the knob may cause damage.

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/wall 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 screw 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.

Fine-tuning the image size and clarity

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

Sharpen the image by rotating the focus ring.

Correcting keystone

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, esides adjusting the height of the projector, you can use Auto Keystone or Keystone manually correct it following one of the these steps.

• Using the remote control or projector

Press on the remote control or / on the projector to display the Keystone correction page. Press ▼to correct keystoning at the top of the image. Press ▲to correct keystoning at the bottom of the image. When Keystone OSD pops up, long press OK for 2 seconds to reset Keystone.

When Keystone OSD pops up, long press PIC MODE for 2 seconds to enable Auto Keystone.

Connection

When connecting a signal source to the projector, be sure to:

I. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted.

Maintenance

Care of the projector

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface. Please be sure to turn off the projector and let it cool down completely before cleaning the lens.

• Use a canister of compressed air to remove dust.
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the projector surface and cabinet material.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown procedure as described in Shutting down the projector on page 26 and unplug the power cord.

• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent. Then wipe the case.

Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.

Storing the projector

If you need to store the projector for an extended time, please follow the instructions below:

• Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please refer to Specifications on page 43 or consult your dealer about the range.
• Retract the adjuster feet.

• Pack the projector in its original packing or equivalent.

Transporting the projector

It is recommended that you ship the projector with its original packing or equivalent.

Lamp information

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. Lamp Usage Time = (x+y+z) hours, if Time used in Normal mode = x hours Time used in Eco mode = y hours Time used in SmartEco mode = z hours

2. Equivalent Lamp Hour = hours

$$ \alpha = \frac {A ^ {\prime}}{X} x X + \frac {A ^ {\prime}}{Y} x Y + \frac {A ^ {\prime}}{Z} x Z, i f $$

X = lamp life spec of Normal mode

Y = lamp life spec of Eco mode

Z = lamp life spec of SmartEco mode

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

For Time used in each lamp 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.

When you calculate Equivalent Lamp hour manually, it will probably have deviation from the value shown in OSD menu since projector system calculates Time used for each lamp mode in "Minutes" then rounds down to an integer in hours shown in OSD.

To obtain the lamp hour information:

I. Go to SYSTEM SETUP: ADVANCED Menu > Lamp Settings and press OK. The Lamp Settings page appears.
2. Press ▼ to select Lamp Timer and press OK. The Lamp Timer information is displayed.

You can also get the lamp hour information on the INFORMATION menu.

Extending lamp life

- Setting the Light Mode

Go to PICTURE Menu > Advanced > Light Mode and select a suitable lamp power from among the provided modes.

Setting the projector in Economic or SmartEco mode extends lamp life.

Lamp mode Description
Normal Provides	full lamp brightness
Economic	Lowers brightness to extend the lamp life and decreases the fan noise
SmartEco	Adjusts the lamp power automatically depending on the content brightness level while optimizing display quality

- Setting Auto Off

This function allows the projector to turn off automatically if no input signal is detected after a set period of time to prevent unnecessary waste of lamp life.

To set Auto Off, go to SYSTEM SETUP: BASIC Menu > Auto Off and press ◀/▶.

Timing of replacing the lamp

When the Lamp 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 lamp 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 LAMP 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 Lamp or Temp indicator still lights up after turning the power back on, please contact your dealer. See Indicators on page 41.

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 OK to dismiss the message.
	The lamp MUST be replaced before the projector will operate normally.Press OK to dismiss the message.

"XXXX" shown in the above messages are numbers that vary depending on different models.

Replacing the lamp

• 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, 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.

• 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.

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

• Remove the lamp cover from the projector.

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

- Do not insert your fingers between the lamp and the projector. The sharp edges inside the projector may cause injuries

1. Remove the safety mylar.

2. Disconnect the lamp connector.

3. Loosen the screw(s) that secure the inner lamp.

4. Lift the handle so that it stands up.

5. Use the handle to slowly pull the lamp out of the projector.

- Pulling it too quickly may cause the lamp to break and scatter broken glass in the projector.

- Do not place the lamp in locations where water might splash on it, children can reach it, or near flammable materials.

- Do not insert your hands into the projector after the lamp is removed. The sharp edges inside the projector may cause injuries. If you touch the optical components inside, it could cause color unevenness and distortion of the projected images.

1. Insert the lamp connector.
