Step 2: Install the Management Terminal and Log In
You can install the management terminal on your mobile phone or computer as needed, or simply use the web version in your browser without installation.

After opening the management terminal, click "Login" and enter your mobile number and verification code to log in. 
After logging in, you will see the default built-in program on the program interface, which can be used for casting tests.
Step 3: Cast Programs to the Display Terminal
After logging into the management terminal, click "Programs" in the main menu to view the built-in programs. Select the program you want to cast and click the "Cast" button. 
After clicking the "Cast" button, you will be prompted with multiple casting methods. Since your device is not yet bound, choose "Cast by entering device dynamic code" here. You can explore other casting methods later as you become familiar. 
Enter the dynamic code displayed on the display terminal device. If the device is not on the main interface, press the return key to go back. After entering the code, click the confirm button in the upper right corner. 
A dialog box will pop up to confirm whether the binding is complete. If you see the following dialog, the device has been successfully bound. 
Click "Confirm" to continue to the casting settings dialog. The default settings are fine; just click "Confirm" to complete the casting. 
The device will immediately synchronize, and playback will begin once synchronization is complete.
