*1: When address 39 is on, SW1 enables the transmitting amplifier output (pin 58) signal, and SW4 enables the receiving
amplifier output (pin 7) or KT (pin 55) signal. If voltage is not supplied to pin 31 (V_CC) (power is off), the status of SW1
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.
