How much light is needed?
The K750r 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 K750r 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 K750r is
much less in brightly lit environments or when the K750r is placed in direct sunlight.
The K750r stores energy automatically, even when turned off. This stored energy allows you to use the K750r without light for a
while. With a full charge, the K750r 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 K750r? Use the Light-check hot key. The K750r tells you if it’s getting
enough illumination.
1.
Make sure the K750r 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
Reading the Light-check LED.
