3. PC Mode
3-1. Preface
The transceiver is programmed by using a personal com-
puter, a programming interface (KPG-22A/22U, USB adapter
(KCT-53U)) and programming software (KPG-152D).
The programming software can be used with a PC. Fig-
ure 1 shows the setup of a PC for programming.
3-2. Connection Procedure
1. Connect the transceiver to the personal computer with
the interface cable and USB adapter (when the interface
cable is KPG-22A, the KCT-53U can be used).
Note:
• You must install the KPG-22U driver in the computer to
use the USB programming interface cable (KPG-22U).
• You must install the KCT-53U driver in the computer to
use the USB adapter (KCT-53U).
• When using the USB adapter (KCT-53U) for the first time,
plug the KCT-53U into a USB port on the computer with
the computer power ON.
2. When the POWER is switched on, you can immediately
enter user mode. When the PC sends a command, the
transceiver enters PC mode.
When data is transmitting from the transceiver, the red
LED lights.
When data is receiving by the transceiver, the green LED
lights.
Note:
• The data stored in the personal computer must match
Model Name and Model Type when it is written into the
EEPROM.
• Do not press the [PTT] key during data transmission or
reception.
3-3. KPG-22A Description
(PC programming interface cable: Option)
The KPG-22A is required to interface the transceiver with
the computer. It has a circuit in its D-sub connector case that
converts the RS-232C logic level to the TTL level.
The KPG-22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.
3-4. KPG-22U Description
(USB programming interface cable: Option)
The KPG-22U is a cable which connects to a USB port
on a computer.
When using the KPG-22U, install the supplied CD-ROM
(with driver software) in the computer. The KPG-22U driver
runs under Windows XP, Vista or 7.
3-5. KCT-53U Description (USB adapter: Option)
The KCT-53U is a cable which connects the KPG-22A to
a USB port on a computer.
When using the KCT-53U, install the supplied CD-ROM
(with driver software) in the computer. The KCT-53U driver
runs under Windows 2000, XP or Vista (32-bit).
3-6. Programming Software KPG-152D Description
The KPG-152D is the programming software for the
transceiver supplied on a CD-ROM. This software runs un-
der windows XP, Vista or 7 on a PC. The software on this
disk allows a user to program the transceiver via Program-
ming interface cable (KPG-22A/22U).
3-7. Programming with PC
If data is transferred to the transceiver from a PC with the
FPU, the data for each set can be modified.
Data can be programmed into the EEPROM in RS-232C
format via the SP/MIC jack.
In this mode the PTT line operate as TXD and RXD data
lines respectively.

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.
If the password is incorrect,
“CLN.LOCK.R”/ “CLN.LOCK.W”
is redisplayed. (with error tone)
