Troubleshooting Hints

Faxback Doc. # 2255

The Handheld Trackball is an example of superior design and craftsmanship,

and should last for years. However, if the trackball does not seem to

function properly, or a problem arises, check the following:

° Make sure the connector is firmly plugged into the serial or the mouse

port.

° Make sure you have selected the correct serial port.

° Check to see if the cable is broken or has any sharp bends.

° If the cursor appears on the screen but does not move, make sure you have

installed the correct driver.

° If the cursor moves erratically or jumps on the screen, make sure you

have selected the proper mouse driver.

° If the cursor moves irregularly across the screen, clean the trackball.
