Frequently Asked Questions


Can I change the functions of the multimedia keys?

No, these are fixed functions. They operate with the default program that is set on the computer for that function.

How do I configure my mouse buttons for left/right handed usage?

Follow the steps in the mouse settings page

Is it required to turn off the product to save power?

This product uses standby (sleep) mode to save battery power. When the product is not moving or there is no signal from the USB receiver, it will turn sleep-mode on, to save battery power.

To make sure that there is no signal still going from the computer to the product, when the product is not used (since some computers continuously power their USB-ports, even when the computer itself is switched off), we recommend to doublecheck the power management options of the USB-port, if switching the product on/off is not an option.

Solving problems

I get the wrong letters and/or symbols when typing on my computer.

If your keyboard isn't typing the correct characters, you may have the incorrect input language selected.
Please check the language preference settings of your system. If the correct language is not present, add this language to the system.
If you use more than one language on your system, make sure to select the correct one.

Set the correct language as explained in the keyboard settings page

Sometimes letters are missing when typing.

  • Clean your keyboard from dust and crumbles.
  • If you are using it with a TV, make sure that your TV and/or the app, supports all symbols and characters of the keyboard.
  • Improve wireless performance.

The multimedia keys are not working.

Not all programs are supporting multimedia keys.
  • For best compatibility, use Windows Mediaplayer and Internet Explorer.
  • Ensure that the Multimedia program you wish to control is selected as Default in the system properties.
  • If still not working, uninstall any other programs/drivers related to keyboards.

The mouse arrow shakes, moves strangely or does not move at all.

  • Try using the mouse on a different surface or use a mousepad.
  • Clean the sensor on the bottom of the mouse with a dry cloth.
  • Improve wireless performance.

I get an error during installation.

To solve errors like:
  • "Unrecognized USB device"
  • "Device driver software was not successfully installed"
  • "Can not find driver"

Please follow the installation trouble shooting guide.
