Section 6: Lamp Information
6-1. Metal Halide Projector Lamp
Under normal operating conditions, the lamp should last approximately 1000 hours. However, after time, the
lamp brightness will slowly decrease. The projection lamp contains mercury and should be disposed of
according to local regulations.
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.
Display or Reset Lamp Operation Hours
The LAMP RESET button is a recessed button. Use a paper clip or pen point to press the LAMP RESET
button (1) on the projector control panel (Figure 6-1) and the current lamp operating hours (2) will display.
The lamp reset screens will time-out within 5–10 seconds if no selection is made.

Change Lamp Message
After 1000 hours of lamp operation, the message CHANGE LAMP will display for 30 seconds each time the
machine is powered on. This message is an indication that it is time to install a new lamp.
For best results, the lamp should be replaced after 1000 hours of usage. See Section 6-2. Using a lamp beyond
1000 hours is not recommended because there is an increased potential for the lamp to burst when it gets old.
