Note 1:
PAD control is shown below. Note that Echo Canceller, PAD 3 and PAD 4 are bypassed when the MODE
switch is set to “0”.
Note 2:Regarding speech communication, PAD values set on SW12-1 through SW12-6 are applied. In the other
cases (ex. data communication), PAD values are set according to the order of CPU.
