Maintenance Tips        

• Complete cool-down cycle: Always let the projector fan finish before powering off or unplugging.
• Avoid frequent switching: Repeated on/off cycles reduce lamp life and stability.
• Keep filters clean: Dirty air filters cause overheating and early lamp failure. Clean or replace regularly.
• Proper handling only: Do not touch the lamp glass—use the housing to avoid oil damage and hotspots.
• Use surge protection: Protect the lamp from voltage spikes and unstable power supply.
• Ensure correct installation: Fully seat the DT01291 lamp module to prevent flickering or ignition issues.
• Maintain ventilation clearance: Blocked airflow significantly reduces UHP lamp lifespan.
• Replace at end-of-life signs: Dim output, color shift, or delayed start indicates replacement time.
