1 After changing the printed circuit board, write the up-to-date
Firmware following the instructions in the service manual.
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-141D, select your desired item (Model Name
and Frequency) from the Model > Product Information menu,
then use Program > Write Data 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 Enter Program > Test Mode, then adjust the various
adjustment data (PC Test mode) as described in the service
manual.
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-141D.
Note:
When using the ESN Validation function of Trunking, the ESN
number changes when the circuit board is changed (the number
is written on the circuit board); the Trunking system cannot
be accessed. Maintain the ESN data of the Trunking System
following the new ESN.
When a new printed circuit board is used, the KENWOOD ESN
changes, as does the Transceiver Information display of the
KPG-141D, but this does not have any effect on the operation of
the transceiver.
If changing to the original ESN, please contact our service center.
