2-4. After Changing the PCB
1. After changing the printed circuit board, write the up-
to-date Firmware following the instructions in the "RE-
ALIGNMENT 4. Firmware Programming Mode".
2. Using the KPG-109D, select your desired item (Model
Name and Frequency) from the Model > Product Informa-
tion menu, then use Program > Write to the repeater to
write the FPU data (PC Programming mode).
When writing to the repeater, 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. For the X53-414, 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-109D or KPG-110SM.
Note:
• When a new printed circuit board is used, the Kenwood
ESN changes, as does the Repeater Information display
of the KPG-109D, 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.
• Re-installing other parts from original unit to Service unit
is not required after changing to Service unit.
