USER GUIDE
The whole image appears to be unstable or misplaced
Press reset.
Adjust the frequency and tuning settings (instability), or the image
position settings (misalignment).
Check that you are using a source with compatible resolution.
The projector may be connected to a source with a non-standard
computer (or video card). Adjust the frequency and position of the
image.
Cooling fan is not working when lamp is lit
If the fan does not work the projector must not be used and should
be returned to your dealer for repair.
The remote control is not working
The red LED on the remote control should flash when transmitting. If
not, check the ON/OFF switch or the batteries.
Make sure you point the remote control at the projection screen or
directly at the IR receivers. The front red LED indicator flashes when
receiving signals from the remote.
The maximum range of the IR transmitters is 15m (50 feet) - Are you
standing close enough?
If the effective range of the transmitters is significantly reduced, the
remote control needs new batteries.
The desktop mouse is not working
Remember to follow this sequence when connecting the mouse:
- Connect the mouse cable.
- Connect the projector power cable
- Power on the computer
You must boot the computer after the cable has been connected for
it to recognise the mouse. If you are unsure whether this was the
case, reboot your computer.
Are the mouse cable (and mouse adapter) connections secure?
Check the mouse driver settings on the computer
