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.

Make sure the K750 is turned on.
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.

adequate light

Reading the Light-check LED

Light-check LED flashes green. The K750 is receiving enough light and is ready for use.
Light-check LED flashes red. The K750 requires more light to continue working on a long-term basis.

Note: If the Light-check LED produces no light, please see Help with setup for more information.

Using the Solar App

Want an easy and more visual way of checking the available light falling on the K750 while keeping track of the keyboard’s energy reserve? Download and install the Solar App from www.logitech.com/k750/solarapp

The Solar App operates in the background and notifies you whenever there is a change (up or down) in the K750’s energy reserve.
Try to keep the Light-check gauge pointing at 100 lux or higher to make sure the K750 will have plenty of energy.
To bring the Solar App to the foreground, press the Light-check hot key on the keyboard. The Solar App will pop up, and the Light-check gauge will activate immediately.

Note: Not available on Windows RT.

Is the K750 turned on? Slide the keyboard Off/On switch to Off and then to On position.
Re-establish the connection. Use the Unifying software to reset the connection between the K750 and Unifying receiver. Refer to the Unifying section in this guide for more information.
Restart the computer.
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.
Download and use the Solar App. This handy widget gives you an easy and more visual way of checking the available light hitting the K750 while keeping track of the keyboard’s energy reserve. Download the Solar App from www.logitech.com/k750/solarapp (Not available on Windows RT.)

Wireless product not working properly when also using a USB 3.0 device****

When using a USB 2.0 2.4GHz wireless peripheral device (such as a mouse, keyboard, or headphones) with a PC that also has a USB 3.0 peripheral device plugged in, you may experience erratic operation caused by interference. This is especially likely to happen when using USB 3.0 remote hard drives or flash drives.
This interference may result in:
– Delayed response to mouse or keyboard inputs
– Missing keyboard characters or mouse commands
– Decreased operating distance between the USB 2.0 wireless device and its receiver

There are some techniques that can help early adopters of USB 3.0 to mitigate potential problems with their existing 2.4GHz wireless devices:

– If your PC has multiple USB 2.0 connectors available, separate your USB 3.0 and USB 2.0 receivers by as much distance as possible. For example, if your PC has a choice of USB 2.0 connectors, use the one on the opposite side of the PC from the USB 3.0 connector.
– Position your USB 2.0 receiver as close as possible to your wireless peripheral (mouse, keyboard, headphones, etc.).
– Use a standard, USB-extender cable to position your USB 2.0 wireless receiver as far away as possible from your USB 3.0 connector.
– A USB-extender cable is available for Logitech customers who are experiencing this problem (click here for more information).

NOTE: A USB 3.0 connector sometimes referred to as Super Speed USB or SS, normally has a blue plastic insert in the connector. Unlike a USB 2.0 connector which has 4 pins within the connector, a USB 3.0 connector has 9 pins.

Move your USB 2.0 wireless receiver to the opposite side of your computer:

Make sure your USB 2.0 wireless receiver is in the USB 2.0 connector closest to your wireless peripheral:

Use a USB extended cable to position your wireless receiver as far away from your USB 3.0 peripheral as possible:
