5.3.5 After Changing the PCB
(1) After changing the printed circuit board, write the up-to-
date Firmware.
(2) Using the KPG-D7, select your desired item (Model Name
and Frequency) from the Model > Product Information
menu, then use Program > Write Data to the repeater to
write the FPU data (PC Programming mode).
When writing to the repeater, 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
"ADJUSTMENT".
(4) For the XC1-329, attach the new labels corresponding to
the new printed circuit board. (Refer to the images next
ESN Label Layout.)
(5) If necessary, write the FPU data used by the customer with
the KPG-D7.
Note:
· When a new printed circuit board is used, the KENWOOD
ESN changes, as does the Repeater Information display of
the KPG-D7, but this does not have any effect on the
operation of the repeater.
· 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.
