Cleaning the remote control
Avoid getting dirt, dust or hand lotion on the remote’s trackball. If
the trackball gets dirty, it will not work properly. Follow these steps
to clean the trackball and the remote control.
1.
Turn off the projector.
2.
Using 2 pointed objects, such as pens, remove the trackball cover.
Put the pointed ends into the two holes in the trackball cover.
3.
Turn the cover counter-clockwise about one-half turn until it
comes off.
4.
Remove the trackball.
5.
Wipe the trackball gently with a soft, dry cloth. If necessary,
dampen the cloth with a mild detergent. Do not use alcohol sol-
vents on the trackball.
6.
If necessary, use a cotton swab to clean the inside of the trackball
mechanism. Be very careful not to press hard on the rubber
roller; if it gets out of alignment, the trackball will not work prop-
erly.
7.
Replace the trackball.
8.
Replace the trackball cover. Turn it clockwise to lock it in place.
