“Service TX-RX unit” Data
The following data is written on the service TX-RX unit:
After Changing the PCB
(1) Using the KPG-171D, select your desired item (Model
Name) 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.
(2) Enter Program> Test Mode, then adjust the various ad-
justment data (PC Test Mode) as described in the “SEC-
TION 4 ADJUSTMENT" .
(3) If necessary, write the FPU data used by the customer
with the KPG-171D.
Note:
• When a new printed circuit board is used, the KENWOOD
ESN changes, as does the Transceiver Information dis-
play of the KPG-171D, but this does not have any effect
on the operation of the transceiver.
• If changing to the original ESN, please contact our service
center.
