By extending the screws behind the sidebuttons, you can reduce the post-travel.
[22] Check the mouse buttons
![](https://cdn.shopify.com/s/files/1/0496/4384/7843/files/22_1024x1024.jpg?v=1684936761)
If the mouse buttons touch the shell in the front before they activate, you need to calibrate them.
[23] Calibration
![](https://cdn.shopify.com/s/files/1/0496/4384/7843/files/23_1024x1024.jpg?v=1684936801)
To fix the mentioned issue, extend the screws in the mouse buttons half a turn to the left and check again.

![](https://cdn.shopify.com/s/files/1/0496/4384/7843/files/24_1024x1024.jpg?v=1684936853)
To calibrate the pre-travel, turn the screws in the clips to the left and pull down the mouse buttons.
[25] Install drivers
