12 Positioning your projector

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.

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.

High Altitude Mode

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.

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 23 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.

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. 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 = -AX–‘ + A-Y–‘ y + A-Z–‘ z + A-A–‘ a
, 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.
