license key so that you can use all its features after the initial installation, which is valid for 60 days and has no capacity limitation. By default, the temporary 

license is enabled. When the temporary license key expires, the relevant features will be disabled and a permanent license key must be obtained to continue 

using them.

normally. During daily maintenance, avoid connecting the SMA to the external network or using external storage media at will to ensure the safety of 

the SMA, and regularly back up the SMA system and Command View License, which can be used for recovery once the SMA fails to work properly.
