• Insert the batteries
• Switch the mouse on (ECO) with the button on the bottom
• Connect the USB-receiver to the computer without using a hub or extension cable.
• The computer will recognize the mouse and install the built-in driver. This might take a few moments.
• The mouse is ready to use.

This product doesn't need any drivers to function.
Just connect and the product should work.

Yes, it is possible to press multiple buttons simultaneously. 

Please note that this doesn't mean that all buttons can be pressed simultaneously, since this depends on the specific hardware of a mouse. Mice may have the hardware limitation that the thumb buttons can't be used together with left/right/mid click.

We would advise to check the batteries.

And, if not already set, change the mode to ECO mode to improve the battery life

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.

К сожалению задать кнопкам другую функцию не представляется возможным, так как мышь работает со стандартным драйвером системы. Специальной программки, которая позволила бы изменения функций кнопок, в комплекте не прилагается.  

Можно посмотреть в интернете, может быть можно скачать программку для программирования кнопок

Вот например с этого сайта http://www.highrez.co.uk/downloads/XMouseButtonControl.htm

Но заметьте, что это неофициальное решение и мы не можем дать гарантии, что данное ПО вообще будет работать с данной мышью.

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 would advise to reinstall the mouse:

• Make sure that the computer is up-to-date via windowsupdate.com
• Remove all errors from the Device Manager, esp in the mouse and USB sections
• Remove the USB-receiver
• Switch the mouse off with the button on the bottom
• Restart the computer
• Doublecheck that the battery is full. When in doubt, use a new battery.
• Switch the mouse on (to ECO) with the button on the bottom
• After the computer has fully restarted, connect the USB-receiver to the computer without using a hub or extension cable.
• The computer will recognize the mouse and install the built-in driver. This might take a few moments.
• The mouse is ready to use.
• If the error persists, test the mouse with fresh batteries on another USB-port and on another computer.

First test if the issue only persists on the laptop, and not on a desktop computer.

If the issue persists only on the laptop, we would advise to check if the mouse receives (enough) power from the laptop to function by following the steps below. Check the functoning of the mouse between each step.

1. Check the power saving option of the USB-port
   Device Manger > USB > right-click on the device > Properties > uncheck: Allow the computer to turn off this device to save power
2. Check the hardware, mouse and wireless connections
   • Connect the receiver to a different port. If possible, try the USB port at the back of the computer, since they typically have more power available.
   • Replace the battery.
   • Reestablish wireless connection by unplugging the receiver when the computer is on, then waiting for at least 10 seconds before plugging the receiver back in.
3. Disable the fast startup option. This will initialize all drivers on startup, so the time needed to start the computer might be longer.
   • Press the Windows key and X at them same time > Power Option.
   • Click Choose what the power button does.
   • Click Change settings that are currently unavailable.
   • Untick the box for Turn on fast startup (recommended) > Click Save changes to save and exit.
   • Restart the computer.

• 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.

Although our keyboards and mice are designed for use with computers, they can be used on PS4. However please note, most PS4 games do not support a keyboard and mouse.

When using a (wired) keyboard or mouse with a PS4, make sure it connects well with the PS4. If the PS4 has a connection on the back, connect the keyboard/mouse to the USB-connection on the back of the PS4. Or alternatively use an extension cable or USB hub.

You can use our mice and keyboards on the Xbox One.

Please note that Xbox One supports the use of mouse and keyboard in some games and apps, but it doesn’t work for every game or app. The game or app publisher must enable this feature for their content.
