and improve the positioning performance of GPS module.

We recommed using suspending damping installation, especially use DoS vibration

absorbing mount which product by FeiYu Tech.(You can find purchase method from FeiYu
official website:

)

Installation process as follows:(You need a allen driver)

1.Use screws to install the four support columns on the baseboard;

2.Stick the solid foam pads (dampers) to the cover board four interior Angle position;
