• POWER BUTTON/STATUS LED
Indicates projector status as follows:
• Solid green = AC power present, ready to turn on (lamp not lit)
• Flashing green = lamp is warming up or cooling down; keypad functions not allowed
• Off = Lamp lit, projector functioning normally
• Alternating green/red = Lamp problem (door open, unable to strike, end of life), user
intervention likely to fix problem
• Flashing red = Over temperature, user intervention (clear vents, turn on AC) may fix
problem
• Solid red = Error that requires servicing (fan fail, Power-on self-test fail etc.)
• EXHAUST VENT
Warm air exits the projector through this vent. Ensure that it is not blocked.
• INTAKE VENT
Internal fans draw cool air into the projector through this vent.
• PROJECTION LENS
The inside of the lens barrel is threaded to accommodate a standard, 72-mm lens filter.
For example, with a smaller screen you can install a neutral-density filter to reduce the
overall light output.
If needed, a light shield accessory is provided with the lens to minimize stray light
emissions. (Use it only when the vertical offset is 50% of the screen height or greater.)
The light shield attaches to the end of the lens (or to the filter, if used).
• FRONT IR SENSOR
Receives infrared signals from the remote control unit.
