Trouble shooting for K350
This problem is likely to be a lost connection. The connection between the keyboard and the
USB receiver can be lost due to several reasons such as:
 Low batteries
 Moving the USB receiver from one USB port to another
 Moving the USB receiver to another computer
 Plugging the USB receiver into a USB hub or other unsupported device such as a KVM
switch (your USB receiver must be plugged directly into your computer)
 Using your wireless keyboard on metal surfaces
 Radio frequency (RF) interference of more powerful wireless devices such as:
o Wireless speakers
o Computer power supplies
o Monitors
o Cellular telephones
o Garage door openers
Eliminate any problem sources mentioned above that might be affecting your keyboard.
