12 TROUBLE-SHOOTING
This is a checklist to help you pinpoint any problem that may arise. Check
the symptoms carefully if you experience any problem. The cure may be at
your fingertips!
Always check that the ON/OFF indicator on the projector
flashes when a key on the remote control is pressed. This
indicates that the projector is receiving signals from the
remote control.
