Receiver signal input pin.
Inputs a receiver signal from the side
tone preventive circuit network.
Receiver gain control pin,
Receiver signal output pin.
Capable of controlling the frequency
characteristic and gain of the receiver
system with the external parts C and F
of the Pins19 and 20. The receiver sig-
nal/HOLD TONE signal/KEY IN TONE
signal is output to the Pin20 by the
HC/DMC/SPC control.
Receiver amplifier signal input pin,
Receiver output (1) pin,
Receiver output (2) pin.
Inputs a receiver signal from the Pin20
to the Pin21. BTL output at the Pins20
and 23.
Speaker amplifier signal input pin.
Inputs a receiver signal from the Pin20.
Pin No.

KT/HT signal input pin,
Digital VR ON Pin.
Inputs a KEY IN TONE or HOLD
TONE signal. If the Pin14 is set to Low,
the KT signal is output to the receiver,
and if the Pin13 is set to Low, the HT
signal is output to the curcuit and speak-
er. The receiver gain is improved 6dB
by setting this pin to Low instantaneous-
ly.
