then increase contrast (

(

) until the crosshatch is displayed. Adjust contrast and brightness to their proper
settings.
2) The room lighting may be too bright.
3) The projector may be too far from the screen. Move the projector closer to the screen.
The maximum throw distance is 25 feet.
4) Were the lens covers accidentally left on? Remove the lens covers.
Symptom:
While in use, the projector suddenly become non-responsive to keypad
commands, even when using a built-in keypad.
Cause/Remedy
:
1) Although rare, it is possible that an internal software error occurred
which has put the software in a non-ending loop. This might occur if a power spike
interfered with the projector's internal processor system. To fix this problem, leave the
projector plugged in and using a small screw driver or ball point pen, press the recessed
RESET button on the back panel. This operation will reset the projector's processor
without affecting memories or display settings.
Symptom:
The projector does not respond to the
STBY
or
MUTE
keys.
Cause/Remedy:
1) you may not be holding down the key long enough to initiate the
action. Like

Symptom:
Th
e projector does not respond to an IR Remote keypad.
Cause/Remedy:
1) The projector's IR keypad listening status may be turned off. Press
PROJ then *
to turn
on the listening status of all projectors, or press
PROJ
followed by
the projector's identity number to turn on the listening status of the projector you want to
respond.
2) The keypad's protocol (A or B) might not match the projector's IR protocol setting.
Refer to section 2.3,
Hardware Setup
for instructions on how to check and change the
keypad's protocol setting. However, if the projector's setting is ''Off' the remote keypad
will not respond. You may have to configure the keypad for built-in operation to gain
control of the projector.
3) The IR keypad may be too far away from the projector or screen. Use the IR keypad
closer to the projector or screen. Also ensure the keypad is pointed directly at the screen
or the front of the projector.
4) The viewing path between the IR keypad and the projector (or screen or switcher) may
be restricted. Ensure there is a clear line-of-sight between the keypad and the projector
(or screen or switcher).
5) The sensor may be disabled per the Keypad Options menu (
UTIL 6 then 1
).
6) The batteries in the IR keypad may be weak. Replace the batteries in the keypad. See
section 2.3 for battery installation instructions.
7) There may be unusual lighting conditions in the room which effect IR keypad
operation. Determine if such conditions exist and correct.
