1. The D8 series(D8/D8H/D8HD) uses special light source of discharging gas. Please do not turn on or
off D8 series frequently. Every turn on/off interval should be more than 30 minutes. Otherwise, it may
damage the bulb easily and make it unworkable. When the bulb automatically turns on and off or its
brightness is obviously weak, please replace the bulb.
2. Wait for more than 7 minutes after you shut down D8 series with the remote control. Then disconnect
the D8 series from the main power supply after the fan stops. Please wait for more than 3 minutes to
turn on the D8 series after it is turned off by pressing “power” or shut down abnormally. Otherwise it
would directly shorten the life of the bulb or even damage the bulb.
3. In order to cool the D8 series adequately, please stop using the remote control for 2 minutes after D8
series is shut down. The remote control will not function within 2 minutes. 2 minutes later, the remote
control function will resume automatically.
4. Because the temperature is high inside the D8 series bulb box, exhaust vents are distributed in the side
and bottom of the D8 series. Make sure not block up, cover or fill in things into the vents, and also
avoid touching high voltage electricity or circuit in order not to damage D8 series or cause an
accident.
5. There are protective circuits and alarming device inside the D8 series. When the internal temperature
rises caused by improper environment or blocked vents, the projector will alarm automatically. At this
time, the projector should be shut down.
6. As the LCD has a particular characteristic of sequence reversal, when the contrast is not in
consistency with the brightness, there will appear a few bright frames in the screen, which is normal.
7. When there is some light spots or black dots in the image, please enjoy the D8 series at ease as it will
not affect the D8 series’s function at all. According to international inspection standard(less than 8
dots), it is normal.
8. The D8 series will work normally under normal surrounding temperature. When the surrounding
temperature is too high, round black spot will appear and become bigger and bigger in the image
during playing, please turn off the D8 series so as to avoid damaging the LCD chip.
9. Please don’t put the D8 series onto or near calorific and hot objects, or put it into airtight cabinet. Do
put it in the ventilated place!
10. Avoid using D8 series in condition of moisture, high-temperature, vibrancy, dust and radiation. When
it needs to be moved, please take or put it gently!
11. When the D8 series is installed hanging on the ceiling, it is advised to use outlet with a switch, which
can be used to turn off the main power supply after the D8 series is turned off.
12. When the D8 series needs to be installed hanging, please refer to picture(2)
