To check if the Logitech K750 keyboard is getting enough light, you can use the Light-check hot key. Here's how:
1. Make sure the K750 keyboard is turned on.
2. Press the Light-check hot key. The Light-check LED on the keyboard will flash either green or red, or it won't produce any light at all.
- If the Light-check LED flashes green, it means the K750 is receiving enough light and is ready for use.
- If the Light-check LED flashes red, it means the K750 requires more light to continue working on a long-term basis.
- If the Light-check LED produces no light, please refer to the Help with setup section in the user manual for more information.
Additionally, you can download and use the Solar App from the Logitech website. The Solar App provides a more visual way of checking the available light falling on the K750 keyboard and keeps track of its energy reserve. It also notifies you whenever there is a change in the keyboard's energy reserve. You can download the Solar App from www.logitech.com/k750/solarapp.
Remember, the K750 keyboard requires only a modest level of light to operate and store energy. Indirect sunlight or indoor illumination is sufficient, but a moderate level of room lighting is recommended for much of the day. The K750 can store energy automatically, allowing you to use it without light for a while. With a full charge, the K750 can operate up to three months in total darkness before needing a recharge.
