Help with setup: keyboard not working
• Check the Unifying receiver. Also, try changing USB ports.
• Move closer? Try moving the K750 closer to the Unifying receiver, or plug the Unifying receiver into the Wireless
extender if you are using a tower PC.
• Is the K750 turned on? Slide the keyboard Off/On switch to Off and then to On position.
• Re-establish the connection. Use the Unifying software to reset the connection between the K750 and Unifying receiver.
Refer to the Unifying section in this guide for more information.
• Restart the computer.
• Press the Light-check hot key. If the Light-check LED produces no light, the K750 is out of energy. To use the
K750 again, significantly increase the amount of light over the keyboard to a level you might see in a brightly lit office.
It may take a day or two for the K750 to recharge when exposed to this increased level of illumination, but only several
hours if the K750 is placed in direct sunlight.
Note: Any time the Light-check LED flashes red automatically, the K750 is nearly our of energy and needs more light to keep working
on a long-term basis.
• Download and use the Solar App. This handy widget gives you an easy and more visual way of checking the available
light hitting the K750 while keeping track of the keyboard's energy reserve. Download the Solar App from
