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 (ModelName and Frequency) from the Model > Product Infor-mation menu, then use Program > Write Data to the re-peater 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] tocontinue 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 tothe new printed circuit board. (Refer to the images belowfor label placement.)5. If necessary, write the FPU data used by the customerwith the KPG-109D or KPG-110SM.Note:• When a new printed circuit board is used, the KENWOODESN changes, as does the Repeater Information displayof the KPG-109D, but this does not have any effect onthe operation of the transceiver.• If changing to the original KENWOOD ESN and NXDNESN, please contact our service center.• Re-installing other parts from original unit to Service unitis not required after changing to Service unit.TROUBLE SHOOTING
