Method of confi rming “Original TX-RX unit” and
“Service TX-RX unit”
The 0
Ω
resistor (R963) is mounted
on the “0-11” silk print part of the
Service TX-RX unit (X57-9270-13).

Note:
• The
0
resistor (R962 and R963) is used to differentiate
the destination with a visual check. These are not con-
nected with any PCB pattern; they are specifi cally for pro-
duction control. There is no need to change the mount of
two resistors.
• There is no difference between the schematic diagram of
the Service TX-RX unit (X57-9270-13) and the schematic
diagram of the original TX-RX unit (X57-9270-12). (R962
and R963 are connected with GND (ground) only.)

After Changing the PCB
1. After changing the printed circuit board, write the up-
to-date Firmware following the instructions in the “RE-
ALIGNMENT - 6.Firmware Programming Mode”.
2. Using the KPG-111D, select your desired item (Model
Name and Frequency) from the Model> Product Informa-
tion menu, then use Program> Write Data to the Trans-
ceiver to write the FPU data (PC Programming mode).
When writing to the transceiver, a Warning Message, cor-
responding to the item selected, appears. Click [OK] to
continue writing the data.
3. Enter Program> Test Mode, then adjust the various ad-
justment data (PC Test Mode) as described in the “AD-
JUSTMENT”.
4. Attach the new labels corresponding to the new printed
circuit board. (Refer to the images on page 38 for label
placement.)
5. If necessary, write the FPU data used by the customer
with the KPG-111D/111DN.
Note:
• When using the ESN Validation function of NXDN Trunk-
ing, the NXDN ESN number changes when the circuit
board is changed (the number is written on the circuit
board); the NXDN Trunking System cannot be accessed.
Use the KPG-110SM on the NXDN Trunking System side
to reprogram the NXDN ESN number.
• When a new printed circuit board is used, the Kenwood
ESN changes, as does the Transceiver Information dis-
play of the KPG-111D/111DN, but this does not have any
effect on the operation of the transceiver.
• If changing to the original Kenwood ESN and NXDN
ESN, please contact our service center.
