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

This product uses standby (sleep) mode to save battery power.

There is no need to switch it off. 

When the product is not used or there is no signal from the USB receiver, it will turn sleep-mode on, to save battery power.

For storage or travelling we would suggest to remove the batteries to avoid leaking. 

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.

This mouse uses a generic driver of Windows, which doesn't provide a possibility to adjust button functions.

However, you can try with software which is available on internet to configure the buttons.

Please note that this solution is not official, as there is no Trust software available for programming the buttons, and therefore it is not supported, nor is proper functioning of the software guaranteed.

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 recommend fully reinstalling the product, including with new batteries.

Make sure that all errors have been removed from Device Manager, remove the receiver, and then restart the computer.
When the computer has completely restarted, connect the receiver to the computer without using a hub or extension cable.
The computer detects the product and installs the integrated driver. This can take a moment.
The product can now be used.

If the problem persists, test the product on another USB port and another computer to rule out a problem with the computer.

Download the ‘mouse fix software’ in the Downloads-section and follow the instructions in the addendum (available for download in the Downloads section) to solve the issue

Note for Mac-users: The mousefix is not available in a Mac version. However, when you use the mousefix on a Windows PC for your mouse, your mouse will work fine again on a Mac computer.

When you receive the 'wait mouse' message, we advise you to update the computer via Windows Update. Then reinstall the software.

If running Windows update doesn't solve the issue, we ask that you to run the Mousefix software on another computer, preferably with a different operating system.
When you run the Mousefix on the other computer, the mouse will work normally on your computer as well.

• 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.

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.
