The remote control does not
operate normally
1. The battery might have run out
2. You might have inserted the batteries in
the wrong orientations
3. You may be operating the remote control
too far away from the projector's IR sensor
or exceeded the maximum angle of signal
reception ; there might be an obstacle
between the projector and the remote
control or there might be a source of
intense light
near the IR receiver.
4. Ø 3.5mm A wired remote connector
might be connected to the projector's
3.5mm port.
5. The remote control's address is not
consistent with the projector's address.
1. Replace new batteries
2. Make sure the batteries are inserted in the
right orientation.
3. Adjust the distance/angle between the
projector and the remote control and try
again; if there are obstacles between the
projector and the remote or source of
intense light near the IR sensor resolve
these situations and try again.
4. Remove the wired remote cable or
operate the projector using wired remote.
5. Press the ENTER button on the remote
control followed by the Address button
until the panel of the remote control
flashes once

The image appears washed out
or the dark areas appear too
bright

too high.
Lower brightness settings.
The image is blurry
1. The lens may not be in focus.
2. The temperature or humidity of the
projector's working environment may have
changed in mid operation (i.e. going from
cold to warm or dry to humid), leading
to condensation of moisture inside the
projector.
1. Adjust Lines focus.
2. Turn of the projector first and wait for the
moisture in the projector to evaporate.
The color of the image looks
pale
The input signal type (RGBHV/YUV2) might
not have been connected properly
Check to make sure that the connections
between the projector and the input device
are correct.
The image flashes occasionally
1. The cables might not have been properly
connected or the input device itself may
be faulty.
2. If the problem persists, it may also mean
the lamp might be faulty.
1. Make sure the connector and the input
device have been properly connected;
check to see if the input device is in normal
working order.
2. Replace the projector lamp.
The colors of the projected
image are out of place (i.e.
displaying red as blue)
The G/Y, R/Pr, B/Pb cables from the input
might have been incorrectly connected to
the input.
Please make sure the input source has been
correctly connected to the projector.
The noise from the cooling fan
suddenly grew louder
The temperature inside the projector might
have risen.
When the temperature inside the projector
rises, the cooling fan will operate at a higher
speed to discharge the internal heat more
rapidly.
The LED indicator on the
projector’s front panel is
blinking in red
The lamp or the cooling fan could be faulty.
Refer to the definition of page 15: 3.4
