sponds to D
3
, and it is assumed to be H
3
.
Example: If D
3
 = 12288,
H
3
 = 3000
8) Caluculate D
4
  using following equations (decimal
caluculation). (0   D

Example: If D
2
 = 12345 and D
3
 = 12288,
D
4
 = 12345 – 12288 = 57
9) Convert D
4
 into a hexadecimal number to obtain H
4
. (See Table
6-4-1 “Hexadecimal - decimal conversion table” in 6-4. Ser-
vice Mode)
Example: If D
4
 = 57,
H
4
 = 39
10) Enter higher two digits of H
3
 to address: 0A on page: 13.
Example: If H
3
 = 3000,
Select page: 0, address: 10, and set data: 01.
Select page: 3 (13), address: 0A, and set data: 30, then press
the PAUSE (Write) button.
11) Enter H
4
 to address: 0B on page: 13.
Example: If H
4
 = 39,
Select page: 0, address: 10, and set data: 01.
Select page: 3 (13), address: 0B, and set data: 39, then press
the PAUSE (Write) button.
12) Select page: 0, address: 10, and set data: 00.
13) Select page: 3, address: 70, and set data: 10, then press the
PAUSE (Write) button.
14) Select page: 3, address: 70, and check that the data changes to
“11”.
15) Select page: 0, address: 01, and set data: 00.

Node Unique ID No. Input
Note 1:
Perform “2-2. Input of Serial No.” if the data on page 13
has been cleared and original node unique ID No. is un-
certain.
Usually, read the data on page 13 before repair, and write
it after repair.
Note 2:
If reading/writing data on pages 13, set data: 01 to page:
0, address: 10, and then select pages: 3. By this data set-
ting, the pages 13 can be selected.
After the data reading/writing finished, return the data
on page: 0, address: 10 to “00”.
