Logitech K750 Getting Started Manual page 4

How much light is needed?
The K750 requires only a modest level of light to operate and store energy. Indirect sunlight or indoor illumination is fine.
When exposed to dim room light on a continuous basis, the K750 has enough power for use. Because indoor environments
usually have periods of darkness, a moderate level of room lighting is recommended for much of the day. The recharge time
for the K750 is much less in brightly lit environments or when the K750 is placed in direct sunlight.
The K750 stores energy automatically, even when turned off. This stored energy allows you to use the K750 without light
for a while. With a full charge, the K750 can operate up to three months in total darkness before needing a recharge.
Checking for adequate light
How do you know whether there's enough light for the K750? Use the Check Light hot key. The K750 tells you if it's getting
enough illumination.
1. Make sure the K750 is turned on.
Reading the Check Light LED
• Check Light LED flashes green. The K750 is receiving
enough light and is ready for use.
• Check Light LED flashes red. The K750 requires more light
to continue working on a long-term basis.
Note: If the Check Light LED produces no light, please see Help
with setup for more information.
