USER MANUAL LK970 BENQ

1. Please read the user manual / installation guide 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

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 light source is on.

5. The light source becomes extremely hot during operation.

6. 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).

7. 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 light source, use the blank function.

8. Do not operate light sources beyond the rated light source life.

9. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining

10. 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. Under no circumstances should you ever undo or remove any other covers. Refer servicing only to suitably qualified professional service personnel.

11. Do not block the ventilation holes.

- Do not place this projector on a blanket, bedding or any other soft surface. - Do not cover this projector with a cloth or any other item. - Do not place inflammables near the projector. If the ventilation holes are seriously obstructed, overheating inside the projector may result in a fire.

12. Do not stand the projector on end vertically. Doing so may cause the projector to fall over, causing

injury or resulting in damage to the projector.

13. Do not step on the projector or place any objects upon it. Besides probable physical damage to the

projector, doing so may result in accidents and possible injury.

14. 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.

15. Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail.

If the projector does become wet, disconnect it from the power supply's power outlet and call BenQ to have the projector serviced.

16. This apparatus must be earthed.

17. Do not place this projector in any of the following environments.5

English - 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 rolled up. - Locations where excessive humidity, dust, or cigarette smoke may contaminate optical components, shorten the projector's life span and darken the image. - Locations near fire alarms - Locations with an ambient temperature above 40°C / 104°F - Locations where the altitudes are higher than 3000 m (10000 feet). Risk Group 2

1. According to the classification of

photobiological safety of light sources and light source systems, this product is Risk Group 2, IEC 62471-5:2015.

2. Possibly hazardous optical radiation emitted

3. Do not stare at operating light source. May

be harmful to the eyes.

4. As with any bright source, do not stare into

the direct beam. The projector’s light source unit uses a laser. Laser Caution (For China and other regions) This product belongs to CLASS 1 laser product and complies with IEC 60825-1:2014. (For north America) This product belongs to CLASS 3R laser product.and complies with IEC 60825-1:2007.

CLASS 3R LASER PRODUCT

LASER Parameters Cooling notice This Laser Product is designated as Class 3R during all procedures of operation. LASER LIGHT - AVOID DIRECT EYE EXPOSURE. Do not point laser or allow laser light to be directed or reflected toward other people or reflective objects. Direct or scattered light can be hazardous to eyes and skin. There is a potential hazard of eye exposure to laser radiation if the included instructions are not followed. Caution – use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

• LAN For connection to RJ45 Cat5/Cat6 Ethernet cable to control the projector through a network.

• IR IN For use with an IR extender cable to ensure better signal reception from the remote control.

• 12V TRIGGER Trigger external devices such as an electric screen or light control, etc.

• HDBaseT For connection to RJ45 Cat5/Cat6 cable to input uncompressed high-definition video (HD).

• MONITOR OUT Connection to other display equipment for concurrent playback display.

• PC 15-pin VGA port for connection to RGB source or PC.

• USB MINI-B For firmware upgrade only.

• USB TYPE A Support 5V/2A output.

• RS232 Standard 9-pin D-sub interface for connection to PC control system and projector maintenance.

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.

• Ceiling installation must be done by a qualified professional. Contact your dealer for more information. It is not recommended you install the projector yourself.

• Only use the projector on a solid, level surface. Serious injury and damage can occur if the projector is dropped.

• Do not use the projector in an environment where extreme temperature occurs. The projector must be used at temperatures between 32 degrees Fahrenheit (0 degrees Celsius) and 104 degrees Fahrenheit (40 degrees Celsius).

• Screen damage will occur if the projector is exposed to moisture, dust or smoke.

• Do not cover the vents on the projector. Proper ventilation is required to dissipate heat. Damage to the projector will occur if the vents are covered.

Ceiling mount screw: M6 (Max L = 25 mm; Min L = 20 mm) Unit: mm11 English Using the cable tie set The cable tie set helps prevent a cable plug from falling out of the connecting port. It contains the following parts. To use the cable tie set: Using the lens rubber cap When the projector is installed or mounted in any way other than a horizontal position, use the rubber cap to keep the zoom ring from rotating due to its own weight. After the focus and zoom rings are adjusted, follow the illustrations to insert the rubber cap to keep them in position.

1. Firmly plug a cable to a correct port on the

projector. Insert the cable tie head to the cable tie hole right above the connecting port. Note that the cable tie cannot be removed from the hole once it is inserted.

2. Take the cable tie ratchet. Slightly open the

ratchet to surround the connecting cable.

3. Insert the end of the cable tie to the cable tie

ratchet as illustrated.

4. Close the cable tie ratchet by pressing its tab.

5. Move the cable tie ratchet along with the

cable tie to the end of the cable plug. The cable tie installation is done. Cable tie Cable tie ratchet Cable tie head
