What’s in the box?

  • Adjustable height pads for keyboard
  • USB-Micro cable
  • Soft wrist support


How to set it up

Start by turning the Delta upside down and connect the USB-Micro cable to your Delta. Depending on your setup you can choose if you want the cable to go out on the left or the right side.

While Delta is upside down, attach the height pads by sliding them into their slots. Both Delta and the pads are marked with L and R so it is easy to attach them to their specific slots.

Then turn over Delta and put your keyboard in place. Depending of the thickness and size of your keyboard you might have to adjust the pads. If you have a thicker one, just fold out the pads so they become thinner. Your keyboard should always be in line with, or slightly lower, than your Delta.

Basic tips

Position your Mousetrapper between you and your keyboard. The B key on your keyboard should be directly in front to the scoll wheel on the Mousetrapper, as shown in figure 1. If you have a thin keyboard, attach and use the keyboard raisers that comes in the package with your Mousetrapper. Connect them to your Mousetrapper by sliding them into the slots under the unit. The keyboard should always be in line with or slightly lower than your Mousetrapper.

There are two ways of scrolling. You can use the separate scroll wheel or activate auto scroll on the Control Bar. To activate auto scroll, click on the scroll wheel and use the Control Bar to scroll, then deactivate auto scroll by clicking on the scroll wheel again.

The product is configured for PC on delivery. To configure it for Mac, simultaneously press and hold the lower right button, the lower left button (Copy and Paste) and the Control Bar for 3–4 seconds. The LED will flash to confirm the configuration. Repeat the procedure to change back to PC configuration.

The pad can be replaced when it is worn out. You can order new pads via your dealer or directly from

Customising the button functions

We understand the importance of a customized user experience. Just as some people want their screen at a specific angle or their table at a specific height, we believe it should be easy to customize a computer mouse. Thanks to our app, you can make your Mousetrapper unique by configuring the key functions to suit the way you work.
