► Check whether the battery of the keyboard or of the mouse is properly inserted.
► Disconnect the receiver from the computer and reconnect it.
► The receiver may be too far from the keyboard / mouse.

radio frequency.

Insert the receiver into another USB port of your computer.
On systems with a USB 3.0 port, connection problems may occur because of technical reasons.

Do not connect the receiver to a USB port which is very close to a USB 3.0 port which has a USB 3.0 end
device connected (e. g. immediately adjacent USB ports).

Where appropriate, use a USB extension cable to increase the separation.
