the solutions in the “Trouble-shooting” section of the end of this booklet.  If the problem still persists, contact the sales
dealer where you purchased the projector or the service center.
SAFETY PRECAUTIONS
WARNING :  TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
G This projector produces intense light from the projection lens.  Do not stare directly into the lens as possible.
Eye damage could result.  Be especially careful that children do not stare directly into the beam.
