*1: When address 39 is on, SW1 enables the transmitting amplifier output (pin 58) signal, and SW4 enables the receiving

and SW4 is the same as address 39 is in on state.

*2: When setting address 00 and 40 to 47, ‘‘D’’ data may be either ‘‘0’’ or ‘‘1’’.

Note 1: The receiver amplifier ATT is set to −6 dB when power is first applied, when a reset is performed, and when all of the

switches are off.

Note 2: The line amplifier ATT is set to 0 dB when power is first applied, when a reset is performed, and when all of the switches

are off.

Note 3: The electronic volume control is set to 0 dB when power is first applied, when a reset is performed, and when all of the

switches are off.

Note 4: The addresses are given in hexadecimal notation.
