Important safety instructions

Your projector is designed and tested to meet the latest standards for safety of information

technology equipment. However, to ensure safe use of this product, it is important that

you follow the instructions mentioned in this manual and marked on the product.

Safety Instructions

1. Please read this manual before

you operate your projector. Save

it for future reference.

2. Do not look straight at the

projector lens during operation.

The intense light beam may damage

your eyes.

3. Refer servicing to qualified

service personnel.

4. Always open the lens shutter (if

any) or remove the lens cap (if

any) when the projector lamp is

on.

5. In some countries, the line voltage is

NOT stable. This projector is

designed to operate safely within a

mains voltage between 100 to 240

volts AC, but could fail if power cuts

or surges of ±10 volts occur. In

areas where the mains voltage

may fluctuate or cut out, it is

recommended that you connect

your projector through a power

stabilizer, surge protector or

uninterruptible power supply

(UPS).

6. Do not block the projection lens with

any objects when the projector is

under operation as this could cause

the objects to become heated and

deformed or even cause a fire. To

temporarily turn off the lamp, press

ECO BLANK on the projector or

remote control.

Important safety instructions4

Safety Instructions (Continued)

7. The lamp becomes extremely hot

during operation. Allow the projector

to cool for approximately 45 minutes

prior to removing the lamp assembly

for replacement.

8. Do not operate lamps beyond the

rated lamp life. Excessive operation of

lamps beyond the rated life could

cause them to break on rare

occasions.

9. Never replace the lamp assembly or

any electronic components unless the

projector is unplugged.

10. Do not place this product on an

unstable cart, stand, or table. The

product may fall, sustaining serious

damage.

11. Do not attempt to disassemble this

projector. There are dangerous high

voltages inside which may cause death

if you should come into contact with

live parts. The only user serviceable

part is the lamp which has its own

removable cover.

Under no circumstances should you

ever undo or remove any other

covers. Refer servicing only to

suitably qualified professional service

personnel.

12. When the projector is under

operation, you may sense some

heated air and odor from its

ventilation grill. It is a normal

phenomenon and not a product

defect.

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.

Positioning your projector14

Positioning your projector

Choosing a location

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

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.

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 Installation

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 Installation

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 Installation menu

after you turn the projector on.

Positioning your projector 15

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format

each factors in the projected image size.

Projection dimensions

Refer to "Dimensions" on page 57 for the center of lens dimensions of this projector

before calculating the appropriate position.

MS630ST/MX631ST

The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio

For example, if you are using an 120-inch screen, the recommended projection distance is

2422 mm and the vertical offset is 91 mm.

If your measured projection distance is 3.0 m (3000 mm), the closest match in the

"Distance from screen (mm)" column is 3028 mm. Looking across this row shows that a

150'' (about 3.8 m) screen is required.

The screen aspect ratio is 16:10 and the projected picture is in a 16:10 aspect ratio

For example, if you are using an 120-inch screen, the recommended projection distance is

2063 mm and the vertical offset is 40 mm.

If your measured projection distance is 3.0 m (3000 mm), the closest match in the

"Distance from screen (mm)" column is 3094 mm. Looking across this row shows that a

180'' (about 4.6 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.

2. Press POWER or ON to start the projector. As soon as the lamp lights up,

a "Power On Ring 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 36

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 on-screen 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 24 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 appears 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 26 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 the background 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 58 for details.
