carefully as it is your guide through the control menus and operation.
Important safety instructions
Your projector is designed and tested to meet the la test 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.
1. Please read this user manual before you operate your 
projector.  Keep this manual in a safe place for future 
reference. 
2. Always place the projector on a level, horizontal  surface during operation.
- Do not place the projector on an unstable cart, stand, or table as it may fall and be damaged; 
- Do not place inflammables near the projector; 
- Do not use if tilted at an angle of more than 10  degrees left to right, nor at angle of more than 15

resulting in damage.  4. Do not place the projector in any of the 
following environments:
- space that is poorly ventilated or confined. Allow at least 50 cm clearance from walls 
and free flow of air around the projector;
- locations where temperatures may become  excessively high, such as the inside of a car 
with all windows closed;
- locations where excessive humidity, dust,  or cigarette smoke may contaminate optical 
components, shorten the projector’s

5. Do not block the vents holes while the projector 
is on (even in standby mode):
- Do not cover the projector with any item;
- Do not place the projector on a blanket, bedding or any other soft surface.  9. Do not look straight into the projector lens 
during operation. It may harm your sight. 
6. In areas where the mains power supply voltage  may fluctuate by ± 10 volts, it is recommended 
that you connect your projector through a power 
stabilizer, surge protector or uninterruptible 
power supply (UPS) as appropriate to your 
situation.   10. Do not operate the projector lamp beyond the 
rated lamp life. Excessive operation of lamps 
beyond the rated life could cause a lamp to break 
on rare occasions.
7. Do not step on the projector or place any objects  upon it. 11. 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 place liquids near or on the projector.  Liquids spilled into the projector will void your 
warranty. If the projector does become wet, 
disconnect it from the power point and call BenQ 
to have the projector repaired. 12. This projector is capable of displaying inverted 
images for ceiling mount installation. Use only 
BenQs Ceiling Mount Kit for mounting.

13. Never attempt to replace the lamp assembly until 
the projector has cooled down and is unplugged 
from the power supply. 
14. When you think service or repair is required,  take the projector only to a suitably qualified 
technician.
15. 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. See 
page  59.
Under no circumstances should you ever undo or 
remove any other covers. Refer servicing only to 
suitably qualified professional service personnel.
Notice
Please keep the original packing for possible future 
shipment. If you need to pack your projector after 
use, adjust the projection lens to an appropriate 
position, put the lens cush ion around the lens, and 
fit the lens cushion and projector cushion together 
to prevent damage during transportation.
Moisture condensation
Never operate the projector immediately after 
moving it from a cold lo cation to a hot location. 
When the projector is exposed to such a change 
in temperature, moisture may condense on the 
crucial internal parts. To prevent the projector 
from possible damage, do not use the projector 
for at least 2 hours when there is a sudden change 
in temperature.
Avoid volatile liquids
Do not use volatile liquids, such as insecticide or 
certain types of cleaner,  near the projector. Do 
not have rubber or plastic products touching the 
projector for a long time. They will leave marks on 
the finish. If cleaning with a chemically treated 
cloth, be sure to follow the cleaning product’s 
safety instructions.
Disposal
This product contains the following materials 
which are harmful to human bodies and 
environment.
•   Lead, which is contained in solder.

  Overview
EnglishRemote 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 new 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 case and sliding  it back up into position. Stop when it clicks into 
place.
Notes on handling batteries
•  Do not mix old batteries with new ones , or mix different types of batteries.
•  Avoid leaving the remote contr ol and batteries in an excessive hot or humid environment like the 
kitchen, bathroom, sauna, sunr oom, or in a closed car.
•  Dispose of used batteries accord ing to the battery manufacturer’s instructions and local environment 
regulations for your region.
•  If the remote control will not be used for an exte nded period of time, remove the batteries to avoid 
damage to the control from possible battery leakage.
Remote control operation
•  Make sure that there is nothing positioned  between the remote control and the infrared 
(IR) sensors on the projector that might 
obstruct the IR beam from the remote control 
reaching the projector.
•  The effective range of the remote control is up  to 8 meters, and at an angle within 30 degrees 
from the center of the IR beam. Always aim 
straight at the projector, however, most 
screens will also reflect the IR beam to the 
projector.
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 damage to person and property.
If you intend to mount your projec tor 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 improp er 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 Ke nsington lock compatible security cable and attach 
it securely to both the Kensington lock slot on the pr ojector and the base of the ceiling mount bracket. This 
will perform the secondary role of restraining the pr ojector should its attachment to the mounting bracket 
become loose.
