If your trackball isn't working, the problem is likely a lost connection. The connection between the trackball and Unifying receiver can be lost for many reasons, including:
- Low battery charge
- Moving the Unifying receiver from one USB port to another
- Moving the Unifying receiver to another computer
- Plugging the Unifying receiver into a USB hub, KVM switch or other unsupported device (NOTE: Your USB receiver must be plugged directly into your computer.)
- Using your cordless trackball on metal surfaces
- Radio frequency (RF) interference from other sources, such as:
- Wireless speakers
- Computer power supplies
- Monitors
- Cell phones
- Garage door openers
Try to rule out these and other possible problem sources that might be affecting your trackball.
