To determine if your Logitech K750 keyboard is receiving adequate light, you can utilize the Light-check hot key. First, ensure your K750 is powered on. Then, press the Light-check hot key. The Light-check on the keyboard will then indicate the light status. If the LED flashes green, the keyboard has sufficient light for operation. A red flash indicates that more light is needed for optimal long-term functionality. If the LED doesn't illuminate, consult the setup section in the user manual for further guidance. In addition, consider using the Logitech Solar App, which is available for download from the Logitech website. This app provides a visual representation of the light levels and monitors the keyboard's energy reserve, notifying you of any changes. The K750 functions well with modest light, such as indirect sunlight or indoor illumination. It can store energy and operate in darkness for up to three months when fully charged.
