[3] EEPROM Mode
When replacing EEPROM IC, necessary data are not recorded
inside; “Protect area read error” (“ERR 80”) occurs.
inside; “Protect area read error” (“ERR 80”) occurs.
To avoid this state, write the data into the corresponding device.
1. Enter the test mode and check set data values of each address
according to the EEPROM set data table on the right.
If necessary, change the set data values.
If necessary, change the set data values.
NOTE: (Data are written into EEPROM in the procedure 4 below.)
(Do not stop power supply to the product)
2. Exiting the EEPROM mode from the address value display state.
(Press the POWER key once in the address value display state.)
(The product enters the test mode route state.)
3. Exiting the test mode
(Press the POWER key once in the test mode route state.)
(Then the data are written into EEPROM. After the write
operation, the product enters the standby state.)

4. After checking that the product enters the standby state, stop
power supply to the product.
(This operation initializes the error state.)
* Operation ends.
