Note:
When there is no DSL WAN connection, insert the 3G network card, and the
system will perform a dial-up automatically. If the DSL WAN connection and the
3G connection coexist, the DSL WAN connection takes priority over the 3G
connection. When the DSL WAN connection starts to perform a dial-up, the 3G
connection will be disconnected. If the DSL WAN connection has been
established, you may manually perform a 3G dial-up, and then the DSL WAN
connection will be disconnected.
