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 the user manual / installation
guide and marked on the product.
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 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 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 serious damage.
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.
- 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).

• To optimize your projection quality, we suggest you 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.

Adjusting the projector position
Shifting the projection lens
• 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.

重要安全說明
本投影機經設計完成及測試通過，符合資訊科技設備的最新安全標準。然而，為確保您安全地使用本產品，請務必
遵循本使用手冊 /安裝指南的指示與產品本身所標示的指示。
1. 操作投影機之前，請先閱讀本使用手冊 /安裝指南。請妥善保存本手冊，以供日後參考。
2. 操作時請勿直視投影機鏡頭。強光可能會造成您的視力受損。
3. 有關維修問題，請洽詢合格的維修人員。
4. 投影機的光源亮起時，請務必打開或移除鏡頭蓋 （如果有的話）。
5. 操作期間光源會變得很燙。
6. 有些國家的電壓不穩定。本投影機所設計安全操作的電壓區間為 100 至240 伏特交流電，但如果發生斷電或功
率驟然起伏達 ±10 伏特就會發生故障。如果在主電壓可能會波動或中斷的區域使用本投影機，建議您經由穩壓
器、雷擊突波保護器或不斷電系統 (UPS) 連接電源。
7. 當投影機在運作中，請勿讓任何物品擋住投影的鏡頭，因為這樣可能會使得該物品遇熱變形甚至造成火災。若
要暫時關閉光源，請使用空白功能。
8. 請勿使用超過額定壽命的光源。
9. 請勿將投影機放置在不平穩的手推車、架子或桌子上。否則投影機可能會掉落，造成嚴重損壞。
10. 請勿打開投影機的機殼。機身內含有危險的高電壓配件，萬一接觸人體時可能會造成電擊死亡。
請勿在任何狀況下打開或移除其它部分的護蓋。有關維修問題，請洽詢合格專業的維修人員。
11. 請勿阻塞通風口。
- 請勿將投影機放置於毯子、寢具或其它柔軟物品的表面上。
- 請勿用布或其它物品覆蓋投影機。
- 請勿將易燃物放在投影機附近。
如果通風口嚴重阻塞而使投影機內部過熱，可能會引起火災。
12. 請勿將投影機直立擺放。因投影機可能會不穩摔落，導致人身受傷或投影機損壞。
13. 請勿踩在投影機上，或在上面放置任何物品。這樣除可能導致投影機損壞外，還可能造成意外及人身受傷。
14. 當使用投影機時，您也許會在通風口附近感覺到些微的熱風與氣味。此乃正常現象，並不是產品有瑕疵。
15. 請勿將液體放在投影機附近或放在投影機上。液體如果濺到投影機內，可能導致投影機故障。投影機如果不慎
弄濕，請立即拔掉電源線，並聯絡 BenQ，安排投影機的維修事宜。
16. 本裝置必須接地。
17. 請勿將本投影機放置在下列任何環境中。
- 不通風或密閉場所。投影機離牆面至少要有 50 公分的距離，且周圍空氣要流通。
- 過熱場所。例如：車窗緊閉的車內。
- 潮濕、多塵或煙霧瀰漫的場所。因為可能會污染光學元件，縮短投影機的使用壽命，並使投影影像變暗。
- 靠近火災警報器的場所。
- 周圍溫度超過 40°C/104°F 的場所。
- 海拔超過 3000 公尺 （10000 英呎）的場所。

• 為了達到最佳的投影品質，建議在非灰色區域內進行投影。
• 所有測量值皆為近似值，可能會與實際的大小有些許出入。
如果您要將投影機固定安裝在某個地方，BenQ 建議您先使用這台投影機作實地測試，確認其投影尺寸和
距離，並參考其光學特性之後再做安裝。這將會幫助您找到最佳的吊掛位置。

• 天花板安裝必須由合格的專業人員進行。如需詳細資訊，請聯絡您的經銷商。不建議自行安裝投影機。
• 投影機只能在堅固、平坦的表面上使用。若投影機掉落，則可能造成嚴重傷害和損壞。
• 請勿在極熱或極冷環境中使用投影機。投影機必須在華氏 32 度（攝氏0 度）至華氏 104 度 （攝氏 40 度）
之間的環境下使用。
• 若投影機處於潮濕、多塵或煙霧瀰漫的環境將會導致螢幕損壞。
• 請勿阻塞投影機的通風口。必須保持良好通風以排除熱氣。若擋住通風口將會導致投影機損壞。
