If the wireless keyboard does not operate properly, the battery may need to be replaced. If you do not intend to use the wireless keyboard for an extended 
period of time, remove the battery to avoid possible damage from battery leakage.

If the wireless keyboard is left unused for 20 minutes or longer, your computer enters Sleep mode. To bring it back into Normal mode, press any key 

on the wireless keyboard.

To maintain good communication, operate the wireless keyboard within the distance limitations of keyboard: approximately 33 feet (10 m) from your 
computer.

Avoid using any wireless devices that exchange radio signals on the 2.4 GHz band near your wireless keyboard. These devices may create radio 
interference, causing the keyboard to stop working properly.

Do not place metal furniture or objects near your computer or wireless keyboard, as this may create radio interference, causing the keyboard to stop 

working properly.

Be sure to use an alkaline battery. Using an incompatible battery can damage the wireless keyboard.
