4.Wireless Clone Mode
4-1. Outline
“Wireless Clone Mode” copies the transceiver data to an-
other transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.
4-2. Example
The transceiver can copy the programming data to one or
more transceivers via RF communication.
The clone source and clone target/s must be in wireless
clone mode.
4-3. Operation
1. To switch the clone target/s to Wireless Clone mode,
press and hold the [<B] key while turning the transceiver
power ON.
2. Wait for 2 seconds. “CLONE” appears on the LCD, fol-
lowed by “FRQTBL 1”.
3. Select a channel table number using the [Selector] knob.
4. To switch the clone source to Wireless Clone mode,
press and hold the [<B] key while turning the transceiver
power ON.
5. Wait for 2 seconds. “CLONE” appears on the LCD, fol-
lowed by “FRQTBL 1”.
6. Select the same channel table number as the clone tar-
get/s.
7. Press the [S] key on the clone source to begin data trans-
mission.When the clone target starts to receive data, the
green LED will light and “CLONING” will appear on the
LCD.The source unit will display “MASTER”.
8. When the clone source finishes sending data, a “confir-
mation” tone will sound and “COMPLETE” will appear on
the LCD. If data transmission failed while cloning, the tar-
get unit will produced an error tone and “CLONE NG” will
appear on the LCD.
9. If the cloning fails, no data will be available in the target
unit when it is returned to User mode.
10.When the cloning is successful, the target unit's “Scan”
and “Key lock” functions will return to their default values
(Scan = OFF, Key lock = OFF).
11.The source will remain in clone mode after cloning. The
target unit will return to user mode after a successful
cloning.
Note:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers wireless clone mode is configured as
“Disabled”, the transceiver cannot enter Clone mode.
• The table shown below will cover the frequency tables
used for wireless cloning.
• Wireless clone mode cannot be entered in battery low
state.
• A unit cannot be a “Source Unit” if it is unprogrammed. If
the [S] key is pressed, an “error” tone will sound.
• Once a unit is set to be the source, it cannot be a target
after the data has been transmitted. This protects the
data in the source unit.
• MSK signaling is used in cloning.
• Electronic interface may cause a failure in data transfer
during Wireless Clone, such as when waveforms or elec-
tromagnetics are being performed at the workbench.
• Wireless clone mode can be used ONLY by the autho-
rized service personnel.
• The wireless clone mode setting must be configured as
“Disable” before being delivered to the end-user.
• To wireless clone, replace the antenna from both the
source transceiver and the target transceiver with a dum-
my load.
• The transmit output power is automatically set to Low in
Clone mode.
4-4. Adding the Data Password
If the Data password is set to the transceiver, you must
enter the password to activate a clone mode.The maximum
length of the password is 6 digits.
The following describes how to enter the password.
1. Press and hold the [<B] key for 2 seconds while turning
the transceiver power ON.
2. “CLN.LOCK.R”(When the Read authorization password
is set to the transceiver.) / “CLN.LOCK.W” (When the
Overwrite password is set to the transceiver.) is displayed
on the LCD.
3. If the [selector] knob is rotated while “CLN.LOCK.R”/
“CLN.LOCK.W” is displayed, the number (0 to 9) flashes
on the LCD.
When you press the [C>] key, the currently selected num-
ber is determined.
If you press the [A] key, the least digit of the password is
deleted.
If you press the [S] key after entering the password in this
procedure, “FRQTBL 1” is displayed if the entered pass-
word is correct.

CIRCUIT DESCRIPTION
2-2. First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q406 to pro-
duce a first IF frequency of 38.85MHz.
The resulting signal passes through the XF401 MCF to
cut the adjacent spurious and provide the optimum charac-
teristics, such as adjacent frequency selectivity.
2-1. Front End (RF Amplifier) Circuit
The signal coming from the antenna passes through the
transmit / receive switching diode circuit (D201, D202, D203
and D204) and a BPF (L418 and L419), and is then ampli-
fied by the RF amplifier (Q407).
The resulting signal passes through a BPF (L419, L418,
L491, L414 and L413) and goes to the mixer. These BPFs
are adjusted by variable capacitance diodes (D408, D407,
D405, D404 and D403).The input voltage to the variable ca-
pacitance diodes is a regulated voltage output from the DC
amplifier (IC811).

CIRCUIT DESCRIPTION
2-5. Audio Amplifier Circuit
The demodulated signal from IC401 is sent to an AF am-
plifier through baseband IC (IC812), and is routed to an au-
dio power amplifier (IC815) where it is amplified and output
to the speaker.
2-6. Squelch Circuit
Part of the AF signal from the IC401 enters the FM sys-
tem IC (IC401) again, and the noise component is amplified
and rectified by a filter and an amplifier to produce a DC
voltage corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of
the MCU (IC820). IC820 determines whether or not to output
sounds from the speaker by checking if the input voltage is
higher or lower than the preset value.
To output sounds from the speaker, IC820 sends a high
signal to the AF_CONT line and turns IC815 on through
Q813, Q814, Q818 and Q819.
3.Transmitter System
3-1. Microphone Amplifier Circuit
The signal from the microphone is limited by the AGC
circuit, which is composed of D807, D808, Q810, Q811 and
the mute switch (Q809). IC812 is composed of a high-pass
filter, low-pass filter and pre-emphasis/IDC circuit.
The signal from the microphone and the low speed data
from the MCU (IC820) enter the baseband IC (IC812) and
pass through each path and are mixed inside the IC.
The output signal from the baseband IC goes to the VCO
modulation input. The other output signal goes to the TCXO
modulation input.

2-3. IF Amplifier Circuit
The first IF signal is passed through a four-pole mono-
lithic crystal filter (XF401) to remove the adjacent channel
signal. The filtered first IF signal is amplified by the first IF
amplifier (Q405) and is then applied to the IF system IC
(IC401).
The IF system IC provides a second mixer, limiting
amplifier, quadrature detector and RSSI (Received Signal
Strength Indicator). The second mixer mixes the first IF sig-
nal with the 38.4MHz signal of the second local oscillator
output (Q403) and produces the second IF signal of 450kHz.
The second IF signal is passed through the ceramic fil-
ter (Wide: CF402, Narrow: CF401) to remove the adjacent
channel signal. The filtered second IF signal is amplified by
the limiting amplifier and demodulated by the quadrature de-
tector with the ceramic discriminator (CD401). The demodu-
lated signal is routed to the audio circuit.
2-4.Wide/Narrow Switching Circuit
Wide and narrow settings can be made for each channel
by switching the ceramic filters CF401 (narrow).
The second IF signal always passes the ceramic filters
CF402 (Wide).
The wide and narrow switching data is output from the
MCU (IC820).
D401 and D402 are switched to ceramic filters when a
narrow mode is selected.
Q404 turns on/off with the Narrow and the IC401 detector
output level is changed to maintain a constant output level
during wide or narrow signals.

CIRCUIT DESCRIPTION
3-3. APC Circuit
The APC circuit always monitors the current flowing
through the drive amplifier (Q204) and the RF power ampli-
fier (Q205) and keeps a constant current. The voltage drop
at R307, R309and R310 is caused by the current flowing
through the RF final amplifier. This voltage is applied to the
differential amplifier IC301 (1/2).
IC301 (2/2) compares the output voltage of IC301 (1/2)
with the reference voltage from IC811. The output of IC301
(2/2) controls the VG of the RF power amplifier and the drive
amplifier to make both voltages the same.
The change of power high/low is carried out by the
change of the reference voltage.
3-2. Drive and Final Amplifier Circuit
The signal from the T/R switch (D18 is on) is amplified by
the RF AMP (Q201) and pre-drive amplifier (Q203) to 50mW.
The output of the pre-drive amplifier is amplified by the
drive amplifier (Q204) and the RF final amplifier (Q205) to
5.0W (1W when the power is low).
The drive amplifier and the RF final amplifier consist of
two MOS FET stages.
The output of the RF final amplifier is then passed
through the harmonic filter (LPF) and antenna switch (D201
and D202) and is applied to the antenna terminal.

Fig. 5 Drive and final amplifier and APC circuit
The TX/RX pin of IC820 goes “high” in transmitting mode,
causing Q7 and Q4 to turn off, and Q5 turn on. The TX/RX
pin goes “low” in receiving mode.
The output from Q4 and Q5 are amplified by a buffer am-
plifier (Q8) and Q2, and then sent to the PLL-IC.
The PLL-ICconsists of a prescaler, reference divider,
phase comparator, and charge pump. The input signal from
pin 10 and 17 of the PLL-IC is divided down and compared
at the phase comparator. The pulsed output signal of the
phase comparator is applied to the charge pump and trans-
formed into a DC signal in the loop filter (LPF). The DC sig-
nal is applied to the CV of the VCO and locked to keep the
VCO frequency constant.
PLL data is output from PL_STB (pin 20), PL_CLK (pin 8),
and PL_DAT (pin 21) of the MCU (IC820). The data is input
to the PLL-IC when the channel is changed or transmission
is changed to reception and vice versa.PLL lock condition is
always monitored by pin 18 (PL_UL) of the MCU. When the
PLL is unlocked, PL_UL goes low.
4. Frequency Synthesizer Unit
4-1. Frequency synthesizer
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL-IC (IC1), and buffer amplifiers.
The TCXO generates 19.2MHz.The frequency stability is
1.5ppm within the temperature range of –30°C to +60°C.The
frequency tuning and modulation of the TCXO are done to
apply voltage to pin 1 of the TCXO.The output of the TCXO
is applied to pin 10 of PLL-IC.
The VCO consists of 2 VCO and covers a dual range
of 437.5750~438.5625MHz and 476.4250~477.4125MHz:
X(CB) or 411.15~481.15MHz and 450~500MHz:X(LMR).
The VCO generates 437.5750~438.5625:X(CB) or
411.15~481.15MHz:X(LMR) for providing the first local
signal for reception. The operating frequency is generated
by Q5 in transmitting mode and Q4 in receiving mode. The
oscillation frequency is controlled by applying the VCO con-
trol voltage, obtained from the phase comparator (IC1) to
the variable capacitance diodes (D6 and D9in transmitting
mode and D10 and D12 in receiving mode)

5-2. Memory Circuit
The Memory circuit consists of the MCU (IC820) and
EEPROM (IC810).The EEPROM has a capacity of 512k bits
and stores the channel information, the last channel data,
the scan on status, and other parameters.
■EEPROM
Note:
The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.

5-3. Low BatteryWarning
The battery voltage is monitored by the MCU (IC820 pin
63: BATT). When the battery voltage falls below the voltage
set by the Low Battery Warning adjustment, the red LED
blinks, notifying the operator that it is time to replace the bat-
tery (when the always option (default setting) under the Bat-
tery Warning function in the FPU is selected). If the battery
voltage falls bellow 5.9V, the transceiver does not transmit
and the warning tone beeps while the PTT switch is pressed.
Low battery warning Battery status
The red LED blinks during
transmission. The battery voltage is low but the transceiver is still usable.
The red LED blinks and the
warning tone beeps while the
PTT switch is pressed.
The battery voltage is low and
the transceiver cannot be used
to make calls.

5. Control Circuit
The control consists of the MCU (IC820) and its peripher-
al circuits. It controls the TX-RX unit. IC820 mainly performs
the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading channel information, frequency, and program
data from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off via the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit via the decode data in-
put.
6) Transmitting tone and encode data.
5-1. Frequency Shift Circuit
The MCU (IC820) and baseband IC (IC812) operates at
a clock frequency of 19.2MHz. The oscillator circuit has the
baseband IC. This oscillator has a circuit that shifts the fre-
quency via Beat shift switch (Q807).
A beat sound may be able to be evaded if “Beat Shift“ is
set to ON when it is generated in the internal spurious trans-
mission modulated sound of the transceiver.

■High-speed data (2-tone)
High-speed data (HSD) is output from pin 3 of the MCU.
HSD deviation made by an adjustment in the MCU is passed
through the low pass CR filter and then applied to the base-
band (IC812).
The signal is mixed with the audio signal and goes to the
VCO and TCXO.
■MSK/DTMF
The MSK/DTMF signal is generated in the baseband IC
(IC812).The signal passes through the D/A converter (inside
the audio processor: IC812) and is routed to the VCO. When
encoding the MSK/DTMF, the microphone input signal is
muted.
6-2. Decode
■QT/DQT
The output signal from the IF IC (IC401) enters the MCU
(IC820) through IC812. IC820 determines whether or not
the QT or DQT matches the preset value, and controls the
AFSW and speaker output sounds according to the squelch
results.
■2-tone
Part of the received AF signal output from the IF IC (IC401)
passes through the baseband IC (IC812) goes to the other
AF amplifier IC808, is compared, and then goes to IC820.
IC820 checks whether or not the 2-tone data is necessary. If
it matches, IC820 carries out a specified operation, such as
turning the speaker on.
■MSK (FleetSync)
The MSK input signal from the IF IC (IC401) goes to
IC812. The decoded information is then processed by the
MCU.
■DTMF
The DTMF input signal from the IF IC (IC401) goes to
IC812. The decoded information is then processed by the
MCU.
7. Power Supply
There are five 5V power supplies and three 3.3V power
supplies: 50M, 50V, 50C, 50R, 50T, 33M, 33MS and 33B.
50M and 33M are always output while the power is on.
33MS is always output, but turns off when the power is
turned off, to prevent malfunction of the MCU.
50C is a common 5V and is output when SAVE is not set
to ON.
50R is 5V for reception and output during reception.
50T is 5V for transmission and output during transmis-
sion.
50V is 5V for the SP/MIC connector.
33B is 3.3V for the baseband IC (IC812).
