Maintenance
Cleaning the Lens
1
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
•
Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other
harsh chemicals might scratch the lens.
2
Lightly wipe the cleaning cloth over the lens in a circular motion.
Replace the lens cap immediately, if you don’t intend to use the projector.
Replacing the Projection Lamp
The lamp hours used timer in the
About menu counts the number
of hours the lamp has been in
use. Twenty hours before the
lamp life expires, the
message “Change lamp” appears
on the screen at startup. If the
maximum lamp time is exceeded,
the lamp will not light. In this
case, after replacing the lamp
you must reset the lamp hours by
simultaneously pressing both
Volume buttons on the keypad
and holding them for 10 seconds.
NOTE: You can order new lamp housings from your dealer or directly from Knoll. See the packing list for
information. Use only a replacement lamp with the same type and rating as the original lamp, model
SP-LAMP-021 or LP21.
1
Turn off the projector and unplug the power cord.
2
Wait 30 minutes to allow the projector to cool thoroughly.
3
Turn the projector on its side
so that the lamp door is facing
you. Using a flat-blade
screwdriver, gently pry the lamp
door from the projector by
placing the screwdriver blade
into the space between the top
of the lamp door and the
projector.
4
Loosen the two captive
screws that attach the lamp
housing to the projector.
5
Detach the lamp connector from the projector by depressing the locking tab on the connector and lightly
pulling it free.
