After Changing the PCB
(1) After changing the printed circuit board, write the up-to-
date Firmware following the instructions in the "2.2
REALIGNMENT - 2.2.6 Firmware Programming Mode".
• Write the Firmware in accordance to the Market. If you
write different Market Firmware, there are times
communication with the FPU is not possible.
(2) Using the KPG-D3/D3N, select your desired item (Model
Name) from the Radio Configuration> Product
Information menu, then use Read/ Write > Write
Configuration to the Transceiver to write the FPU data
(PC Programming mode). When writing to the
transceiver, a Warning Message, corresponding to the
item selected, appears. Click [OK] to continue writing the
data.
(3) Tools > Test/Tuning, then adjust the various adjustment
data (PC Test Mode) as described in the "SECTION 4
ADJUSTMENT".
(4) Attach the new labels corresponding to the new printed
circuit board. (Refer to the images below for label
placement.)
(5) If necessary, write the FPU data used by the customer
with the KPG-D3/D3N.
Note:
• When using the ESN Validation function of NXDN
Trunking, 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 NEXEDGE 1st and NEXEDGE 2nd
Generation Trunking System to reprogram the NXDN
ESN number.
• When a new printed circuit board is used, the KENWOOD
ESN changes, as does the Transceiver Information
display of the KPG-D3/D3N, but this does not have any
effect on the operation of the transceiver.
• If changing to the original ESN, please contact our service
center.
