Lamp Replacement
1. Turn off the projector and wait for the cooling fan to stop.
2. Unplug the power cord. Allow the projector to cool down for approximately one hour
prior to removing the lamp assembly for replacement.
3. Loosen the two captive lamp cover
screws and remove the cover.
4. Loosen the four lamp assembly
mounting screws.
5. Grasp the lamp assembly
handle and pull gently, removing
the lamp module from the
projector housing. As you do
so, the lamp cooling interlock
switch on the inside of the lamp
mounting frame (near the top)
moves to the OFF position.
6. Gently slide the new lamp assembly into the mounting frame. Align the two power
connectors at the top of the lamp assembly with the two sockets at the top of the
mounting frame. Press gently on both sides of the lamp assembly to snap it into
place. As you do so, the lamp cooling interlock switch returns to the ON position.
7. Tighten the lamp assembly mounting screws.
8. Replace the lamp cover and secure the captive lamp cover screws.
9. Plug in the projector and turn it on.
10. Reset the Lamp Timer to zero. To do this, select Lamp Timer Reset from the ISF
Calibration menu and press ENTER. The CL-410/CL-420 shows the number of hours
the projector lamp has been in service and asks you to confirm or cancel the reset.
Press ENTER again to confirm.
