Mouse isn't working

If your M705 mouse isn't working, the problem is likely a lost connection. The connection between the mouse and the Unifying receiver can be lost for several reasons, such as:

• Low battery levels
• Moving the receiver from USB one port to another
• Moving the receiver to another computer
• Plugging the receiver into a USB hub or other unsupported device such as a KVM switch (NOTE: Your Unifying receiver must be plugged directly into your computer.)
• Using your wireless mouse on metal surfaces
• Radio frequency (RF) interference from more powerful devices such as:
  • Wireless speakers
  • Computer power supplies
  • Monitors
  • Cell phones
  • Garage door openers

Before reconnecting your mouse

1. Fix or rule out the potential problem sources listed above.

2. Make sure you have fresh batteries in your mouse (see answer 360023222174 for instructions).

3. Make sure the mouse is turned on (see answer 360023222174 for instructions).

4. Plug the receiver directly and securely into a working USB port on your computer.

5. Turn your computer on.
