5. Are there test patterns or menus present? If so, check your source connections
again.
6. The room lighting may be too bright. Lower the intensity of the room lighting.
Reduce light reflections as much as possible.
7. Increase contrast and/or brightness of image.
8. The projector may be too far from the screen. Move the projector closer.
9. Is the "Status" LED flashing a pattern of yellow and red lights while the "Power"
LED is steady red? This indicates an internal system error that may prevent the
projector from operating. If the problem persists contact a qualified Christie
service technician.
The projector does not respond to the infrared remote keypad...
1. Does the built-in keypad work? If so, check that the keypads are enabled.
2. Does the green "Status" LED flash each time a key is pressed? If not, the
projector is not receiving the keypad's IR signals. Ensure the keypad is directed
to either the front or rear of the projector, or towards the screen.
3. The viewing path between the IR keypad and the projector (or screen) may be
blocked. Ensure there is a clear line-of-sight between the keypad and the
projector (or screen).
4. The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing
Keypad Batteries for instructions on how to replace the batteries.
5. There may be unusual lighting conditions in the room affecting IR keypad
operation. Determine if such conditions exist and correct.
6. The IR keypad may have been disabled for use with this projector(s). Press
to enable broadcasting to all projectors. See 2.10, Keypad Protocols and
Conversion and 3.7, Configuring System Parameters for additional information.
The power is on but the lamp is not...
1. Does the LCD status window say "warming up"?
2. The projector probably became overheated (there is likely an error code flashing
and a message in the LCD status window). Allow to cool and make sure that
nothing blocks projector vents. Do not operate in environments warmer than
35°C (95°F).
3. The lamp may have reached the end of its life. Check the "Lamp Hours" via RS-
lph?

Motorized FOCUS does not work...
1. Remote lens functions are not standard with this projector.
2. If, with a motorized lens mount installed,
the focus tabs move freely by hand, the focus motor (located just below the lens
opening) has likely been bumped forward during rough transit of the projector,
disengaging from its gear. Remove the lens and push the motor into the projector
as far as possible (¼")—if necessary, wiggle the focus tabs slightly so that the
motor engages with its gear internally.
Motorized ZOOM does not work, or is limited...
1. Remote lens functions are optional with this projector.
2. Motorized zoom function is not available for Vista
or 4-7:1, neither of which have a zoom gear, or fixed (non-zoom) lenses.
Lens focus function does nothing and
zoom lenses 2.5-4:1
