SOLUTION
If the image is scaled, press SCALE to return to
the default mode.
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.
Check that the Power ON/OFF switch is ON.
If the fan does not work the projector must not be
used and should be returned to your dealer for
repair.
Make sure you point the remote control at the
projection screen or directly at the IR receiver
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.
Remember that the mouse must be connected
before the computer source is switched on.
Are the mouse cable and mouse adapter
connections secure?
Check the mouse driver settings 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.
