Check for airflow blockage, clean the air filter then turn

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.
