steps for setting master-slave devices:

1 Make sure the box is connected to the network and power supply, and connect the TV with HDMI cable.

2. Open the sidebar, click the “setting” button to enter the setting interface, click more, find and click the linkage mode (Note: the box is wired, and the network mode should also be wired). The linkage mode is the master device by default. Switch to the slave device and wait for the box to restart and the slave configuration is completed.
