Symptom:

noise is generated from "0h49m05s (Track 14)" in the output of "Surround 
channel and surround back channel". 
 
Solution:  
We corrected the firmware so that no malfunction occurs. 
METHOD OF UPDATE via DPMS Read me at first! When you already updated 
the firmware of the unit via "DPMS", it is not necessary to initialize the customer’s 
unit again. At this time, please skip item "Preparation of the update ". 
 
Updating the firmware (Refer to the Instruction Manual.)  
1) Turn the Power Supply of the unit off.  
2) Connect the Ethernet terminal of the unit to the Network line by Ethernet 
straight cable. (Don't use Ethernet cross cable.)   
3) The connection of the network recommends the Ethernet cable for certain 
update.   
4) Turn the Power Supply of the unit on.  
5) The unit sets the Internet. It wishes waiting for about two minutes until 
customer's router ends the setting. 
 
Caution:
 The update doesn't succeed when the customer's set cannot connect to 
the Internet correctly. In this case, please confirm the internet environment in the 
customer’s house. Whether the set is able to receive Internet radio correctly or 
not can be used to determine whether the Internet is properly connected. There
