Why does my Barco PHWU-81B Projector ask for a password?
If you see a password screen on your Barco Projector, it means the PASSWORD FUNCTION in the FEATURE menu has been set to DISPLAY INPUT. You need to enter the password or contact the person in charge of managing the projector to unlock it.
Why does my Barco PHWU-81B say 'HIGH TEMP WARNING'?
If the Barco Projector displays 'HIGH TEMP WARNING', it means the ambient temperature is too high or the intake/exhaust vents are blocked. Try to eliminate the causes of the rise in ambient temperature. Also, remove any objects blocking the intake or exhaust vents.
Why does my Barco PHWU-81B Projector power turn off by itself?
If your Barco Projector's power turns off unexpectedly, it might be due to blocked intake or exhaust vents, or the lamp may be deteriorating.

Also, ensure that AUTO POWER OFF is set to OFF. If the lamp is old, it might need replacing.
