Address

E5, E6, E7

The data of page: 0, address: 10 must be “00”.

Input method:
1)

Select page: 0, address: 01, and set data: 01.

2)

Read the serial No. on the name plate, and take it as D

1

.

Example: If the serial No. is 77881.

D

1 

= 77881

Use six digits of the low rank when a serial No. is more than
seven digits.

3)

Obtain D

2

 and H

1

 corresponding to D

1

 from Table 6-3-2.

Example: If D

1

 is “77881”.

D

2 

= D

= FE

Table 6-3-2.

4)

Input H1 to page: C, address: E5. (Model code input)

Example: If H

1

 is “FE”.

Select page: C, address: E5, set data: FE, and
press the PAUSE button.

5)

Obtain the maximum decimal not exceeding D

2

 from Table 6-

3-3, and take this as D

3

.

Example: If D

2

 is “12345”.

D

3

 = 12288

6)

Obtain the hexadecimal corresponding to D

3

 from Table 6-3-

3, and take this as H

3

.

Example: If D

3

 is “12288”.

H

3

 = 3000

7)

Obtain the difference D

4

 between D

2

 and D

3

. (Decimal

calculation, 0   D

D

4

 = D

2

 – D

3

Example: If D

2

 is “12345” and D

3

 is “12288”.

D

4

 = 12345 – 12288 = 57

8)

Convert D

4

 to hexadecimal, and take this as H

4

.

(Refer to “Hexadecimal-decimal conversion table” in “6-4.
Service Mode”.)

Example: If D

4

 is “57”.

H

4

 = 39

9)

Input the upper 2 digits of H

3

 to page: C, address: E6.

Example: If H
