Section 6: Lamp Information
6-1. Metal Halide Projector Lamp
If the projected image appears dark, the lamp may be getting old and in need of replacement. Under normal
operating conditions, the lamp should last approximately 1000 hours. However, after time, the lamp brightness
will slowly grow dimmer.

 Note
The TEMPERATURE indicator will come on if the
lamp becomes too hot. If this happens, wait for the
fan motor to stop running, turn the power off and let
the projector cool. Check for airflow blockage, clean
the air filter then turn the power on. If the
TEMPERATURE indicator comes on again, call
customer service or your dealer for assistance.
