(2) Installing the antennas
Note:
During installation, ensure that the dial-up antenna, GNSS antenna, Wi-Fi antenna, and Bluetooth antenna
have one-to-one mapping with the antenna interfaces.
When the device performs dial-up, Cellular indicates the primary dial-up antenna, and Diversity indicates the
secondary dial-up antenna. When signals are strong, you only need to install the primary antenna.
When signals are weak, install the primary and secondary antennas.
Installation steps:
1. Make ready the antennas and identify the antenna interfaces.
2. Fasten the antennas in the clockwise direction. Installation of the GNSS antenna is used as an example.
The installation procedures for the other antennas are the same.
