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 at least 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.

1. Make sure the K750 is turned on.

2. Press the Light-check hot key. The Light-check

LED will flash either green or red, or it won’t
produce any light at all. For more information,
see

• 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.
