Keyboard isn't working
In order for your keyboard to work with your device, the device must have built-in Bluetooth capability or be using a third-party Bluetooth receiver or dongle. 
NOTE: The K375s keyboard isn't compatible with a Logitech Unifying receiver, which uses Logitech Unifying wireless technology.
If your system is Bluetooth-capable and the keyboard isn't working, the problem is likely a lost connection. The connection between the K375s keyboard and the computer or tablet can be lost for several reasons, such as:

• Low battery power
• Using your wireless keyboard on metal surfaces
• Radio frequency (RF) interference from other wireless devices, 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 keyboard.

Keyboard frequently loses connection
If your keyboard frequently stops working and you keep having to reconnect it, try these suggestions:

• Keep other electrical devices at least 8 inches (20 cm) away from the keyboard
• Move the keyboard closer to the computer or tablet
• Unpair and re-pair your device to the keyboard

Before reconnecting your keyboard
Before you try to connect your keyboard again:

1. Check to see if you are using fresh non-rechargeable batteries
2. Try using the Windows key or type something to verify it's working with your connected device
