This symbol is intended to alert the user to the
presence of important operation and maintenance
(servicing) instructions in the literature accompanying
the appliance.
Caution: To prevent electric shock do not use this (polarized) plug with
an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.

The main purpose of server dualization is assuring redundancy. Audio can be received from a
secondary or sub-server in the event of trouble or failure from the main server. The Secondary Server is
only used to enable redundancy if the AOE-212N main server is not able to transmit/receive un the
event of network or equipment failure.
When the AOE-212N Client is configured with dual redundant server, The AOE-212N Client will
automatically switch to the secondary or sub-server when the primary server is un expectedly
interrupted allowing for seamless uninterrupted audio broadcast
※Reference: When using only one AOE-212N Server on a network the disconnect probability is
1/1,000. On the other hand, if use dual redundant Servers are used as above, the disconnection
ration will be decreased to 1/1,000,000.
