Display Circuit
The CPU (IC511) controls the shift register (IC508) and
display LEDs.  When the LG line goes high when the trans-
ceiver is busy, Q508 turns on and the green LED on D511
lights.  In transmit mode, the LR line goes high, Q509 turns
on and the red light lights.  Backlighting LEDs for the key
operation unit (D512~D517) and LCD are provided.
When the KBLC line goes high, Q512 turns on, then
Q513 turns on, and the key illumination LED lights.  A volt-
age is applied to the LEDA line to turn on the LCD backlight.

Key Matrix Circuit
The TK-780/780H front panel has ten keys.  Each of them
is connected to a cross point of a matrix of the KEY1 to KEY7
ports of the microprocessor.  The KEY5 to KEY7 ports are
always high, while the KEY1 to KEY4 ports are always low.
The microprocessor monitors the status of the KEY1 to
KEY7 ports.  If the state of one of the ports changes, the
microprocessor assumes that the key at the matrix point
corresponding to that port has been pressed.  Unused
points (KEY1 to KEY7) are also used for foot switch (FSW)
input.

MO is summed with the external pin DI line by the sum-
ming amplifier (IC3) and the resulting signal goes to the D/A
converter (IC5).  The D/A converter (IC5) adjusts the MO
level and the balance between the MO and TO levels.  Part
of a TO signal is summed with an output signal from pin 3
(MO) of IC5 and the resulting signal goes to the MD pin of
the VCO.  This signal is applied to a varicap diode in the VCO
for direct FM modulation.

Encode
The QT, DQT, and LTR signals are output from LSDO of
the CPU (IC511) and go to the D/A converter (IC5) of the TX-
RX unit (A/2).  The DTMF signal is output from HSDO of the
CPU and goes to the audio processor (IC504).  An MSK sig-
nal is output from the audio processor according to the data
(AFDAT) from the CPU.  The signal is summed with a MIC/
MSK signal by the audio processor (IC504), and the resulting
signal passes through an analog switch (IC506) and goes to
the TX-RX unit (A/2) (MO).

Decode
The signal (DEO) detected by the TX-RX unit (A/2) passes
through two low-pass filters of IC501, goes to LSDI of the
CPU (IC511) to decode QT, DQT, and LTR.  The DTMF signal
is decoded by a dedicated IC (IC507) and the resulting signal
is sent to the CPU (IC511) as serial data (STD).

D/A Converter
The D/A converter (IC5) is used to adjust TONE and MO
modulation, beep, AF volume, TV voltage, FC reference volt-
age, and PC POWER CONTROL voltage level.
Adjustment values are sent from the CPU as serial data.
The D/A converter has a resolution of 256 and the following
relationship is valid:
D/A output = (Vin – VDAref) / 256 x n + VDAref
Vin: Analog input
VDAref: D/A reference voltage
n: Serial data value from the microprocessor (CPU)

CIRCUIT DESCRIPTION

Horn Control
The horn switch, consisting of Q4, Q5, and Q6, controls
the horn relay.  It is supplied by the dealer to provide the
external horn alert function.
Q5 disables horn alert, turning on when its base is high,
to inhibit the function.  Normally, the output from IC7 is low,
and Q6 is off; the base of Q4 is about 0V and Q4 is off.
When horn alert is enabled, the output from IC7 goes high
and Q6 turns on.  The base current flows through R58 to Q4
to turn Q4 on.  Q4 can sink a maximum of 100mA.  If the
operational KAP-1 is used, it can drive up to 2A.

PA Switch
If the optional KAP-1 is used, the PA (Public Address)
function becomes available.  In this case, the signal flow
changes as follows;
“PA2” Q507 SW.A SW.B SW.D Public address
L L L H H OFF
HHH L L ON
Power Supply Circuit
When the POWER switch on the TX-RX unit (B/2) is
pressed, the PSW signal goes low.  This signal is inverted by
Q26 and sent to a flip-flop IC (IC15).  This IC outputs a con-
trol signal when the PSW goes low.  When the power turns
on, pin 1 of IC15 outputs a low signal and Q30 turns on.  The
base of Q28 goes high, Q28 turns on, SB SW (Q27) turns on
and power (SB) is supplied to the set.
This circuit has an over-voltage protection circuit.  If a DC
voltage of 20 V or higher is applied to the power cable, D34
turns on and a voltage is applied to the base of Q31.  This
voltage turns Q31 on and turns Q28 and SBSW off.  This
circuit has a TIMED POWER OFF (TOF) function which can
be programmed by software.
It is controlled through pin 6 of IC7.  When the TOF line
goes high, Q22 turns on and then Q25 turns on.  Pin 6 of
IC15 goes high, then pin 1 goes high to turn Q27 off.
