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 Light-check hot key. The K750 tells you if it's getting enough illumination.
