Troubleshooting
If you’re experiencing trouble with the projector, follow these
steps to make sure everything is properly connected before you
call Customer Service for assistance.
1 Check cable connections. Verify that all computer, CableWiz-
ard and power cables are properly connected.
2 Verify that all power is switched on.
3 Verify that the projector has not been switched off with the
standby button on the remote or keypad.
4 If the projector still doesn’t display an image, restart the com-
puter.
NOTE: Macintosh computers
require a specific power-up
sequence: the projector must be
turned on before you turn on the
computer.
5 If the problem still exists, unplug the projector from the com-
puter and check the computer monitor’s display. The maxi-
mum resolution the 610 can display is 800x600 pixels,
preferably 640x480; the maximum resolution the 620 can dis-
play is 1024x768 pixels, preferably 800x600. The problem
might be with the graphics controller in your computer rather
than with the projector. When you reconnect the projector,
remember to turn the computer and monitor off before you
power up the projector. Power the equipment back up in this
order: projector, monitor, computer.
