INTRODUCTION

SCOPE OF THIS MANUAL

This manual is intended for use by experienced techni­cians familiar with similar types of commercial grade com­munications equipment. It contains all required service in­formation for the equipment and is current as of the publica­tion date. Changes which may occur after publication are
covered by either Service Bulletins or Manual Revisions.
These are issued as required.

ORDERING REPLACEMENT PARTS

When ordering replacement parts or equipment informa­tion, the full part identification number should be included.
This applies to all parts : components, kits, or chassis. If the
part number is not known, include the chassis or kit number
of which it is a part, and a sufficient description of the re­quired component for proper identification.

PERSONNEL SAFETY

The following precautions are recommended for person­nel safety :

• DO NOT transmit if someone is within two feet (0.6

meter) of the antenna.

• DO NOT transmit until all RF connectors are verified se-

cure and any open connectors are properly terminated.

• SHUT OFF and DO NOT operate this equipment near

electrical blasting caps or in an explosive atmosphere.

• All equipment should be properly grounded before

power-up for safe operation.

• This equipment should be serviced by a qualified techni-

cian only.

PRE-INSTALLATION CONSIDERNATIONS

1. UNPACKING

Unpack the radio from its shipping container and check
for accessory items. If any item is missing, please contact
KENWOOD immediately.

2. LICENSING REQUIREMENTS

Federal regulations require a station license for each ra­dio installation (mobile or base) be obtained by the equip­ment owner. The licensee is responsible for ensuring trans­mitter power, frequency, and deviation are within the limits
permitted by the station license.

Transmitter adjustments may be performed only by a li­censed technician holding an FCC first, second or general
class commercial radiotelephone operator’s license. There
is no license required to install or operate the radio.

TK -7 60G /7 62G

3. PRE-INSTALLATION CHECKOUT
3-1. Introduction

Each radio is adjusted and tested before shipment. How­ever, it is recommended that receiver and transmitter opera­tion be checked for proper operation before installation.

3-2. Testing

The radio should be tested complete with all cabling and
accessories as they will be connected in the final installa­tion. Transmitter frequency, deviation, and power output
should be checked, as should receiver sensitivity, squelch
operation, and audio output. Signalling equipment operation
should be verified.

4. PLANNING THE INSTALLATION
4-1. General

Inspect the vehicle and determine how and where the
radio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crush­ing wiring, and radio installation to prevent overheating.

4-2. Antenna

The favored location for an antenna is in the center of a
large, flat conductive area, usually at the roof center. The
trunk lid is preferred, bond the trunk lid and vehicle chassis
using ground straps to ensure the lid is at chassis ground.

4-3. Radio

The universal mount bracket allows the radio to be
mounted in a variety of ways. Be sure the mounting surface
is adequate to support the radio’s weight. Allow sufficient
space around the radio for air cooling. Position the radio
close enough to the vehicle operator to permit easy access
to the controls when driving.

4-4. DC Power and wiring

1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse

to blow. Check the vehicle ground polarity before installa-

tion to prevent wasted time and effort.

2. Connect the positive power lead directly to the vehicle

battery positive terminal. Connecting the Positive lead to

any other positive voltage source in the vehicle is not rec-

ommended.

3. Connect the ground lead directly to the battery negative

terminal.

4. The cable provided with the radio is sufficient to handle

the maximum radio current demand. If the cable must be

extended, be sure the additional wire is sufficient for the

current to be carried and length of the added lead.

5. INSTALLATION PLANNING – CONTROL STATIONS
5-1. Antenna system

Control station. The antenna system selection depends
on many factors and is beyond the scope of this manual.
Your KENWOOD dealer can help you select an antenna sys­tem that will best serve your particular needs.

5-2. Radio location

Select a convenient location for your control station radio
which is as close as practical to the antenna cable entry
point. Secondly, use your system’s power supply (which
supplies the voltage and current required for your system).
Make sure sufficient air can flow around the radio and power
supply to allow adequate cooling.

SERVICE

This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and align­ment procedures contained in this manual.

Note

When you modify your radio as described in system set­up, take the following precaution.

The rating of pin 7 (SB) of the accessory connector cable
(KCT-19) on the rear of the radio is 13.6V (1A). Insert a 1A
fuse if you use the SB pin for external equipment.

7

TK -760G/7 62G

OPERATING FEATURES

■ SCAN start condition

One or more non-priority channels must be added to all
channels that can be scanned. The transceiver must be in
normal receive mode (PTT off).

When you activate the key programmed to the scan func­tion, the scan starts. The scan icon "SCN" lights and "SCAN"
is indicated on alphanumeric display.

■ Scan stop condition

The scan stops temporarily if the following conditions are
satisfied.

1) A carrier is detected, then signalling matches on chan-

nels for which receive the signalling is set by the pro-

gramming software.

2) A carrier is detected on the channels for which receiving

signalling is not set by the programming software or

when the monitor (signalling cancel) function is activated.

■ Scan channel types

1) Priority channel is the most important channel for the

scan, and always detects a signal during scan and when

the scan stops temporarily.

2) Non-priority channels detects a signal during scan. For

the channels that can be selected with the group or chan-

nel up/down key when the scan does not occur, adds an

indicator "A" lights.

■ Priority channel setting

A priority channel can be set as follows with the program­ming software (KPG-56D).

1) Specify a priority channel as a fixed priority channel.

2) Make a selected channel, a priority channel.

3) Selected channel
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.

4) Last called channel
The transceiver reverts to the last called channel during
the scan.

5) Last used channel
The transceiver reverts to the last used (transmitted)
channel during scan. "Last used" revert channel includes
talkback function.

6) Selected with talkback
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.

■ Scan end

When you reactivate the key programmed to the scan

function during scan mode, the scan ends.

The scan icon "SCN" and "SCAN" display goes off.

■ Temporarily delete/add

It is possible to delete or add channel temporarily during

scan. When scan stops on unnecessary channel for ex­ample by interference of the other party, activate the delete/
add function (for example press the key), then that channel
is deleted temporarily and scan re-start immediately.

When you would like to add the deleted channel tempo-

rarily to scan sequence, select the desired (deleted) channel
during scan, activate the delete/add function (for example
press the key) before scan re-start.

That channel is added temporarily to scan sequence. The

temporary deleted or added channels are returns to pre-set
delete/add, when the transceiver exits from scan mode.

■ Scan type according to the priority channel

1) When no priority channel is set : Only the non-priority
channels are scanned.

If a non-priority channel stops temporarily, it stops until

there is no signal on the channel.

2) When priority channel is set : Either priority channel is
scanned.
If a non-priority channel stops temporarily, a priority chan­nel signal is detected at certain intervals.
If a priority channel stops temporarily, it stops until there
is no signal on the priority channel.

■ Revert channel

The revert channel is used to transmit during scanning

and set by the programming software (KPG-56D).

1) Priority
The transceiver reverts to the priority channel.

2) Priority with talkback
The transceiver reverts to the priority channel.
If you press PTT during a resume timer (dropout delay
time, TX dwell time) or calling, you can transmit on cur­rent channel to answer to the call however revert channel
is set to priority channel.
After resume time, scan re-starts and transmission chan­nel is return to priority channel.

5. Details of Features

■ Time-out timer

The time-out timer can be programmed in 15 seconds
increments from 15 seconds to ten minutes. If the transmit­ter is keyed continuously for longer than the programmed
time, the transmitter is disabled and a warning tone sounds
while the PTT button is held down. The alert tone stops
when the PTT button is released.

■ PTT ID

PTT ID provides a DTMF ANI to be sent with every time
PTT (beginning of transmission, end of transmission, or
both).

You can program PTT ID "on" or "off" for each group. The
contents of ID are programmed for each channel.

The timing that the transceiver sends ID is program­mable.

BOT : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission.

EOT : DTMF ID (EOT)/MSK ID is sent on end of transmis-

sion.

Both : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission and DTMF ID (EOT)/MSK ID is sent on end

of transmission.

TK -7 60G /7 62G

OPERATING FEATURES

■ Off hook decode

If the Off hook decode function has been enabled, re­moving and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.

■ "TOT" pre-alert

The transceiver has "TOT pre-alert timer. This parameter
selects the time at which the transceiver generates "TOT"
pre-alert tone before "TOT" is expired.

"TOT" will be expired when the selected time passes
from a TOT pre-alert tone.

■ "TOT" re-key time

The transceiver has "TOT" re-key timer. This timer is the
time you can not transmit after "TOT" exceeded. After "TOT"
re-key time expired you can transmit again.

■ "TOT" reset time

The transceiver has "TOT" reset timer. This timer is the
minimum wait time allowed during a transmission that will
reset the "TOT" count.

"TOT" reset time causes the "TOT" to continue even after
PTT is released unless the "TOT" reset timer has expired.

■ OST (Operator Selectable Tone)

(TK-760G K market models only)

The transceiver is capable to have "OST" function and 16
tone pair (QT/DQT).

■ Clear to transpond

The transceiver waits the transpond of 2-tone /DTMF if
channel is busy until channel open. This feature prevents
the interference to other party.

■ AND/OR

You can select AND or OR for option signalling match

conditions.

Alert/Transpond

AND QT/DQT+DTMF (2-tone); Option matches = Action

OR QT/DQT+DTMF (2-tone); Option matches = Action

AF mute open

AND QT/DQT+DTMF (2-tone); Option matches = Action

OR QT/DQT/ID; Signalling only matches = Action

With OR set up, alert/transpond will not function with

only DTMF.

With OR set up, AF mute will not release when only

DTMF matches.

With a conventional channel not set up with QT or DQT,

only the carrier is considered when signalling matches.

■ Auto Reset

If option signalling matches a group set up with option
signalling, option signalling is released. After matching op­tion signalling, option signalling will temporarily reset auto­matically.

■ Dead Beat Disable

If the D.B.D. code matches, a predetermined action will
occur. Whether option signalling is activated or not, when
D.B.D. matches on any channel, the transceiver will become
TX inhibited or TX/RX inhibited. While D.B.D. is active, if the
D.B.D. code + "#" code is received, D.B.D. will disactivate.

When D.B.D. matches, transpond will function. Alert will
not be output, and option signalling match icon will not ap­pear.

6. Option Signalling (DTMF/2-Tone)

Built-in DTMF decoder is available for option signalling.
Built-in 2-tone decoder is available for option signalling.
It is possible to use individual call, group call, D.B.D.

(Dead Beat Disable). D.B.D. is used with DTMF only.

If the option signalling matches, a predetermined action

will occur.

If option signalling matches on a group/channel which is
set up with option signalling, the option signalling indicator
(CALL) will flash and option signalling will be released. The
transpond or alert tone will sound.

The orange LED will flash.

While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute QT/DQT/Carrier.

7. Audible User Feedback Tones

The transceiver outputs various combinations of tones to
notify the user of the transceiver operating state. The main
tones are listed below.

The high tone is 1477Hz, the mid tone is 941Hz, and the
low tone is 770Hz.

■ Power on tone

This tone is output when the transceiver is turned on.
(The high tone is output for 500ms.)

■ Alert tone

This tone is output when the transceiver is TX inhibition
for TOT, and PLL unlocked. It is output until the PTT button
is released.

■ DBD on tone

When a D.B.D. code is received, transpond tone sounds.

■ DBD off tone

When a D.B.D. release code is received, transpond tone
sounds.

4. Check Sum

Executing this function, "TUNING" apears on the display

of the TK-760G while calculation the check sum.

When the calculation is completed, the display returns to

normal and PC displays the check sum of the radio.

5. PC Mode

5-1. Preface

The TK-760G/762G transceiver is programmed using a
personal computer, a programming interface (KPG-46) and
programming software (KPG-56D).

The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.

5-2. Connection Procedure

1. Connect the TK-760G/762G to the personal computer

with the interface cable.

2. When the Power is switched on, user mode can be en-

tered immediately. When the PC sends a command, the

radio enters PC mode.

When data is transmitted from transceiver, the red LED

blink.

When data is received by the transceiver, the green LED

blink.

Notes :

• The data stored in the personal computer must match

model type when it is written into the flash memory.

• Change the TK-760G/762G to PC mode, then attach the

interface cable.

5-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the TK-760G/762G to
the computer. It has a circuit in its D-subconnector (25-pin)
case that converts the RS-232C logic level to the TTL level.

The KPG-46 connects the modular microphone jack of
the TK-760G/762G to the computers RS-232C serial port.

5-4. Programming Software Description

The KPG-56D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program
TK-760G/762G radio via a programming interface cable
(KPG-46).

5-5. Programming With IBM PC

If data is transferred to the transceiver from an IBM PC
with the KPG-56D, the destination data (basic radio informa­tion) for each set can be modified. Normally, it is not neces­sary to modify the destination data because their values are
determined automatically when the frequency range (fre­quency type) is set.

The values should be modified only if necessary. Data
can be programmed into the flash memory in RS-232C for­mat via the modular microphone jack.

6. Firmware Programming Mode

6-1. Preface

Flash memory is mounted on the TK-760G/762G. This
allows the TK-760G/762G to be upgraded when new fea­tures are released in the future. (For details on how to ob­tain the firmware, contact Customer Service.)

6-2. Connection Procedure

Connect the TK-760G/762G to the personal computer
(IBM PC or compatible) with the interface cable (KPG-46).
(Connection is the same as in the PC Mode.)

6-3. Programming

1. Start up the programming software (KPG-56D), select

"firmware program" in the "Program" item, and press the

Return key on your personal computer. This starts up the

firmware programmer.

2. The top screen is displayed. Press any key to advance to

the next screen.

3. Set the communications speed (normally, 57600 bps)

and communications port in the Setup item.

4. Set the firmware to be updated by File select (=F1).

5. Turn the TK-760G/762G Power ON with the [CH

switch held down. Hold the switch down for two sec-

onds until the display changes to "PROG 576", the BUSY/

TX LED lights orange. When "PROG 576" appears, re-

lease your finger from the switch.

6. Check the connection between the TK-760G/762G and

the personal computer, and make sure that the TK-760G/

762G is in Program mode.

7. Press F10 on the personal computer. A window opens

on the display to indicate the writing progress. When the

TK-760G/762G starts to receive data, the BUSY/TX LED

lights green.

8. If writing ends successfully, the LED on the TK-760G/

762G goes off and the checksum is displayed.

(Since the TK-762G does not have a display, check the

checksum with the FPU (KPG-56D).)

9. If you want to continue programming other TK-760G/

762G, repeat steps 5 to 8.

Notes :

• To start the Firmware Programmer from KPG-56D, the
FPRO path must be set up by the KPG-56D setup.

• This mode cannot be entered if the Firmware program­ming mode is set to Disable in the Programming soft­ware (KPG-56D).

• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk be­fore you update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.

6-4. Function

1. If you press the [MON] switch while "PROG 576" is dis­played, the checksum is displayed. If you press the
[MON] switch again (while the checksum is displayed),
"PROG 576" is redisplayed.

2. If you press the [A] switch while "PROG 576" is displayed,
the display changes to "PROG 192" to indicate that the
write speed is low speed (19200 bps). If you press the
[A] switch again while "PROG 192" is displayed, the dis­play changes to "PROG 384", and the write speed be­comes the middle speed (38400 bps). If you press the
[A] switch again while "PROG 384" is displayed, the dis­play returns to "PROG 576".

Note :

TK-762G indicate

19200 bps : The LED flashes green and red alternately.
38400 bps : The LED flashes orange.
57600 bps : The LED lights orange.

Normally, write in the high-speed mode.

7. Clone Mode

Programming data can be transferred from one radio to

another by connecting them via their modular microphone
jacks. The operation is as follows (the transmit radio is the
master and the receive radio is the slave).

1. Turn the master TK-760G power ON with the [
held down. The TK-760G displays "CLONE".

2. Power on the slave TK-760G/762G.

3. Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.

4. Press the [SCN] key on the master while the master dis­plays "CLONE". The data of the master is sent to the
slave. While the slave is receiving the data, "–PC–" is dis­played. When cloning of data is completed, the master
displays "END", and the slave automatically operates in
the User mode. The slave can then be operated by the
same program as the master.

5. The other slave can be continuously cloned. When the
[SCN] key on the master is pressed while the master dis­plays "END", the master displays "CLONE". Carry out the
operation in step 2 to 4.

CIRCUIT DESCRIPTION

Frequency Configuration

The receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil­lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the neces-

sary frequencies. Figure 1 shows the frequencies.

Fig. 1 Frequency configuration

Receiver System

The receiver is double conversion superheterodyne. The

frequency configuration is shown in Figure 1.

■ Front-end RF Amplifier

An incoming signal from the antenna is applied to an RF
amplifier (Q27) after passing through a transmit/receive
switch circuit (D33 and D34 are off) and a band pass filter
(L18). After the signal is amplified (Q27), the signal is fil­tered through a band pass filter (L11, L13 and L15) to elimi­nate unwanted signals before it is passed to the first mixer.
Band pass filters (L18, L11, L13 and L15) have varactor di­odes (D30, D31, D18, D23 and D28).

The voltage of these diodes are controlled by to track the
CPU (IC502) center frequency of the band pass filter. (See
Fig. 2)

■ First Mixer

The signal from the RF amplifier is heterodyned with the
first local oscillator signal from the PLL frequency synthe­sizer circuit at the first mixer (Q15) to create a 49.95MHz
first intermediate frequency (1st IF) signal. The first IF signal
is then fed through two monolithic crystal filters (MCFs :
XF1) to further remove spurious signals.

■ IF Amplifier

The first IF signal is amplified by Q13, and the enters IC5
(FM processing IC). The signal is heterodyned again with a
second local oscillator signal within IC5 to create a 450kHz
second IF signal. The second IF signal is then fed through a
450kHz ceramic filter (Narrow : CF1, Wide : CF2) to further
eliminate unwanted signals before it si amplified and FM
detected in IC5.

CIRCUIT DESCRIPTION

■ Wide/Narrow Changeover Circuit

The W/N port (pin 4) of the shift register (IC510) is used
to switch between ceramic filters. When the W/N port is
high, Q4 turns on and the ceramic filter SW diode (D8, D10)
CF1 turns on to receive a Narrow signal. At the same time,
Q35 turns on and one of the filters is selected so that the
wide and narrow audio output levels are equal.

When the W/N port is low, Q3 turns on and the ceramic
filter SW diode (D8, D10) CF2 turns on to receive a Wide
signal.

■ AF Signal System

The detection signal (DEO) from the TX-RX unit goes to
the audio processor (IC508) of the control unit. The signal
passes through a filter in the audio processor to adjust the
gain, and is output to IC507. IC507 sums the AF signal and
the DTMF signal, BEEP signal and returns the resulting sig­nal to the TX-RX unit. The signal (AFO) sent to the TX-RX
unit is input to the D/A converter (IC6). The AFO output level
is adjusted by the D/A converter. The signal output from the
D/A converter is input to the audio power amplifier (IC13).
The AF signal from IC13 switches between the internal
speaker and speaker jack (J1) output.

■ Squelch Circuit

The detection output from the FM IF IC (IC5) passes
through a band-pass filter and a noise amplifier (Q10) in the
control unit to detect noise. A voltage is applied to the CPU
(IC502). The CPU controls squelch according to the voltage
(ASQ) level. The signal from the RSSI pin of IC5 is moni­tored. The electric field strength of the receive signal can be
known before the ASQ voltage is input to the CPU, and the
scan stop speed is improved.

PLL Frequency Synthesizer

The PLL circuit generates the first local oscillator signal
for reception and the RF signal for transmission.

■ PLL

The frequency step of the PLL circuit is 5 or 6.25kHz. A

16.8MHz reference oscillator signal is divided at IC3 by a
fixed counter to produce the 5 or 6.25kHz reference fre­quency. The voltage controlled oscillator (VCO) output sig­nal is buffer amplified by Q106 (Sub-unit), then divided in IC3
by a dual-module programmable counter. The divided signal
is compared in phase with the 5 or 6.25kHz reference signal
in the phase comparator in IC3. The output signal from the
phase comparator is filtered through a low-pass filter and
passed to the VCO to control the oscillator frequency. (See
Fig. 6)

■ VCO

The TK-760G/762G has VCO in a Sub-unit (A1) housed in
a solid shielded case and connected to the TX-RX unit
through CN101.

The operating frequency is generated by Q103 in trans­mit mode and Q101 in receive mode. The oscillator fre­quency is controlled by applying the VCO control voltage,
obtained from the phase comparator, to the varactor diodes
(D102 and D104 in transmit mode and D101 and D103 in
receive mode). The RX (ST) pin is set low in receive mode
causing Q102 to turn Q103 off, and turn Q101 on. The RX
(ST) pin is set low in transmit mode. The outputs from Q101
and Q103 are amplified by Q106 and sent to the buffer am­plifiers.

■ Unlock Circuit

During reception, the 8RC signal goes high, the 8TC sig­nal goes low, and Q16 turns on. Q18 turns on and a voltage
is applied to the collector (8R). During transmission, the
8RC signal goes low, the 8TC signal goes high and Q29
turns on. Q28 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC3) LD
signal directly. When the PLL is unlocked during transmis­sion, the PLL LD signal goes low. The CPU detects this
signal and makes the 8TC signal low. When the 8TC signal
goes low, no voltage is applied to 8T, and no signal is trans­mitted.

■ Outline

The transmitter circuit produces and amplifies the de­sired frequency directly. It FM-modulates the carrier signal
by means of a varicap diode

■ Power Amplifier Circuit

The transmit output signal from the VCO is amplified to a
specified level of the power module (IC400) by the drive
block (Q22 and Q25). The amplified signal passes through
the transmission/reception selection diode (D16) and goes
to a low-pass filter. The low-pass filter removes unwanted
high-frequency harmonic components, and the resulting sig­nal is goes the antenna terminal.

CIRCUIT DESCRIPTION

■ APC Circuit

The automatic transmission power control (APC) circuit
detects part of a power module output with a diode (D35,
D36) and applies a voltage to IC15. IC15 compares the APC
control voltage (PC) generated by the D/A converter (IC6)
and DC amplifier (IC7) with the detection output voltage to
control Q31 and Q32, generates DB voltage from B voltage,
and stabilizes transmission output.

The APC circuit is configured to protect over current of
the power module due to fluctuations of the load at the an­tenna end and to stabilize transmission output at voltage
and temperature variations.

■ Memory Circuit

The transceiver has a 2M-bit (256k x 8) flash ROM
(IC501) and an 8k-bit EEPROM (IC505). The flash ROM con­tains firmware programs, data and user data which is pro­grammed with the FPU. The EEPROM contains adjustment
data. The CPU (IC502) controls the flash ROM through an
external address bus and an external data bus. The CPU
controls the EEPROM through two serial data lines.

■ Key Matrix Circuit

The TK-760G/762G front panel has function keys. Each
of them is connected to a cross point of a matrix of the KIN0
to KOUT2 ports of the microprocessor. The KOUT0 to
KOUT2 ports are always high, while the KIN0 to KIN2 ports
are always low.

The microprocessor monitors the status of the KIN0 to
KOUT2 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.

CIRCUIT DESCRIPTION

■ Encode

The QT and DQT signals are output from TO of the CPU
(IC502) and summed with the external pin DI line by the
summing amplifier (IC2) and the resulting signal goes to the
D/A converter (IC6) of the TX-RX unit. The DTMF and 2­TONE signals are output from DTMF of the CPU and goes to
the audio processor (IC508). The signal is summed with a
MIC signal by the audio processor (IC508), and the resulting
signal passes through an analog switch (IC509) and goes to
the TX-RX unit (MO).

The D/A converter (IC6) adjusts the MO level and the bal­ance between the MO and TO levels. Part of a TO signal is
summed with MO 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.

■ Decode

• QT/DQT/DTMF

The signal (DEO) detected by the TX-RX unit passes
through two low-pass filters of IC513, goes to TOI of the
CPU (IC502) to decode QT, DQT. The DTMF signal is de­coded by a dedicated IC (IC511) and the resulting signal is
sent to the CPU (IC502) as serial data.

• 2-tone

The detected signal passes through audio processor
(IC508) RX OUT. Then it is filtered through IC504 2-stage
low-pass filtered to enter CPU (IC502) to decode 2-tone sig­nalling.

■ D/A Converter

The D/A converter (IC6) is used to adjust TONE and MO
modulation, AF volume, TV voltage, FC reference voltage,
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)

Power Supply Circuit

When the POWER switch on the control unit is pressed,
the PSW signal goes low. This signal is inverted by Q26 and
sent to a flip-flop IC (IC14). This IC outputs a control signal
when the PSW goes low. When the power turns on, pin 1
of IC14 outputs a low signal and Q20 turns on. The base of
Q19 goes high, Q19 turns on, SB SW (Q23) turns on and
power (SB) is supplied to the set.

This circuit has an overvoltage protection circuit. If a DC
voltage of 20 V or higher is applied to the power cable, D21
turns on and a voltage is applied to the base of Q21. This
voltage turns Q21 on and turns Q19 and SBSW off.
