Method of confi rming “Original Control unit”
and “Service Control unit”
The 0
Ω
resistor (R853) is mounted
on the “R853” silk print part
of the Service Control unit
(X53-4260-12/X53-4260-13).
The shielding plate is soldered
on the Service Control unit
(X53-4260-12/X53-4260-13).

Note:
• The 0
Ω
resistor (R848, R849 and R853) is used to dif-
ferentiate the destination with a visual check. These are
not connected with any PCB pattern; they are specifi cally
for production control. There is no need to change the
mount of these resistors.
• There is no difference between the schematic diagram
of the Service Control unit (X53-4260-12/X53-4260-13)
and the schematic diagram of the original Control unit
(X53-4260-10/X53-4260-11). (R848, R849 and R853 are
connected with GND (ground) only.)

After Changing the PCB
1. After changing the printed circuit board, write the up-
to-date Firmware following the instructions in the “RE-
ALIGNMENT - 6.Firmware Programming Mode”.
2. Using the KPG-111D, select your desired item (Model
Name and Frequency) from the Model> Product Informa-
tion menu, then use Program> Write Data to the Trans-
ceiver 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 ad-
justment data (PC Test Mode) as described in the “AD-
JUSTMENT”.
4. Attach the new labels corresponding to the new printed
circuit board. (Refer to the images on page 36 for label
placement.)
5. If necessary, write the FPU data used by the customer
with the KPG-111D.
