The keys have a special function defined by the operating system. Whether these keys can be changed depends on your computer and operating system. We would advise to consult your computer's manual for more information.

This keyboard doesn't have caps-lock, num-lock and scroll-lock indicators. It has an indicator for low battery.

By pressing the DPI-button you will change the DPI.

There is no visual indication for the DPI selection, other than that the pointer speed on the screen will be faster or slower, depending on the DPI that is selected.

Follow the steps in the mouse settings page

The receiver is stored either inside the product, or inside the battery compartment of the mouse.

It's not possible to provide a replacement receiver for this product.
This is due to the fact that during production the product and receiver receive a unique code, so the product can only communicate with the bundled original receiver.

We advise to doublecheck the batteries, then re-install the keyboard and mouse.

To re-install:
- Disconnect the receiver from the computer
- Restart the computer
- When the computer has fully restarted, connect the USB-receiver to the computer.
- Wait until Windows recognizes it and installs the built-in driver. This might take a few moments. 
- After which a pop-up screen is shown with "Device Setup > Installing device". 
- When this screen has disappeared the installation is finished and the product is ready for use.

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.

Battery life depends on many variables including usage, quality of batteries and environmental factors (such as distance to receiver, nearby metallic objects, surface on which the product is used, etc. etc.).

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.

Make sure that when the battery is draining very fast, that there is no signal still going from the computer to the product, when the product is not used.  Some computers continuously power their USB-ports, even when the computer itself is switched off. You can check this in the Power Management settings of the USB-port.

We advise to check the following:

- Doublecheck that Numlock is enabled. 
- Mouse keys are turned off (control panel > ease of access > change how your keyboard works).
- The keyboard driver is up to date and no errors are visible in the Device Manager.
