Attachment 1  ROM correction 1
»
Take the following procedure for the microprpcessor version 1.0.
1
Procedure
Select “I
2
C DATA” on the adjustment process page 15.
Make the slave address, sub address and data settings in the top line. Move to the bottom line and press the VOL
key. The data will now be uploaded.
The most significant byte represents the slave address, while the following two bytes represent the sub address
and data.
Example: For writing 82 to EEPROM 301h
I

C
DATA
A60000000182

C
DATA
WAIT
Enter “A60000000182” in the top line. Move to “WAIT” in the bottom line and press the VOL key. Momentarily
“SEND” appears onscreen and the data is uploaded. Repeat this step for all the related data. On the ROM correction
1, the procedure is repeated for the EEPROM addresses “0300” to “035B”.
Finally quit the adjustment process mode, and turn off the main power and on again. The microprocessor will be
reset with the ROM correction data written on the EEPROM.
2
Confirmation
Then get the set restarted and take the steps below.
Select “MENU”, “LANGUAGE” and “DEUTSCH” (Onscreen display in German) in this order.
Select “MENU”, “FUNKTIONEN” and “HELLINGKEIT” (Brightness) in this order.
Select “HELLIGKEIT” and [DUNKEL] (Dark) in this order, and make sure the spelling is not [DUNCKEL].
* Be very careful not to take wrong procedural steps. Otherwise the program may run away, freeze or get
in other trouble. In such case, replace the EEPROM with new one.
