Maintenance
If the cursor skips or moves abnormally, clean the ball of TrackMan Live!
1. Remove the retainer ring. On the top
of TrackMan Live!, twist the retainer ring counter
clockwise to remove it.
2. Remove the ball and wipe it with a clean, lint-
free cloth, then blow carefully into the ball-
cage to dislodge dust and lint.
Look for a build-up
of dirt on the rubber roller(s) inside the ball-cage.
3. If dirty, clean the roller(s) using a cotton swab
moistened lightly with isopropyl (rubbing)
alcohol.
After cleaning, make sure the roller(s)
are still centered in their channels. Make sure that fluff
from the swab is not left on the roller(s).
4. Replace the ball and retainer ring.

into the computer’s PS/2 mouse port or serial port.
• For optimal performance, place the receiver at least 8 inches or 20 centimeters
away from other electrical devices, such as the computer, the computer monitor,
or external storages drives.
• Make sure you have installed the batteries correctly.
• Make sure you have set the Range switch to either Hi or Low .
• If you are working on a metallic surface, try using a mouse pad and turning
the receiver on its side for better reception.
