3830 SL  (250-3573)   Using the Built-In Trackball      Faxback Doc. # 1519

Your computer has a built-in trackball that you can use as a pointing device.
As you spin the trackball with your fingertips, the cursor moves in the
direction of the trackball motion. The left and right click buttons emulate
the left and right buttons of a standard mouse.

CAUTIONS:

* Avoid using the trackball with dirty hands. The trackball might not 
  operate correctly if it gets dirty.

* Avoid placing heavy objects on the trackball and click buttons.

* Use the trackball and click buttons gently.

Cleaning the Trackball:

If the trackball gets dirty, it might not operate properly. Follow these 
steps to remove and clean the trackball.

1. Insert the blade of a small, flat-blade screwdriver or a similar tool 
   into the slot between the top left corner of the trackball cover and the 
   computer. Then, carefully pry up and remove the cover, starting with the 
   left side.

Note: Be careful not to break the tabs on the trackball cover.

2. Remove the trackball from the compartment.

3. Clean the trackball with soap and water. Then, rinse the trackball with
   water and thoroughly dry the trackball with a clean, soft cloth.

4. Replace the trackball and its cover.

  computer.
