Troubleshooting

Are you experiencing slow or jerky cursor movement? Try the mouse on a different

surface (e.g., deep, dark surfaces may affect how the cursor moves on the computer screen).

For additional help, refer to the Customer Support telephone numbers on page 129. Also visit www.logitech.com/comfort

for more information about using your product, and for ergonomics.

Is the keyboard turned on? Slide the keyboard Off/On switch to the On position, as shown

in the image below. The keyboard Status icons should light up.

Re-establish the connection. Use the Unifying software to reset the connection between

the keyboard/mouse and Unifying receiver. Refer to the Unifying section in this guide for more

information (p. 14).
