EEPROM WRITING PROCEDURE
EEPROM (IC1402) writing procedure
1. Method for setting the reference temperature value
(This setting should be performed quickly at a room
temperature, between 21°C to 29°C when the PWB is not
hot.)
1
When replacing the EEPROM, wait until it has cooled
down.
2
Connect the main unit using the single MD main PWB.
3
Enter the test mode as shown on page 24.
"EJECT"
4
Press the NORMAL CD MD EDIT button.
"TEMP "
: Measured temperature, : Temperature setting
5
Find the temperature correction value for the current
ambient temperature on the following table. Adjust the
temperature correction value using the VOLUME UP/
DOWN button.
Ambient Temperature
Correction
+ 21.0 °C ~ + 23.2 °C -1 H
+ 23.3 °C ~ + 26.8 °C ± 0 H
+ 26.9 °C ~ + 29.0 °C +1 H
An example: When ambient temperature is 22 °C and
measured temperature is 7A H
Temperature setting = 7A H - 01 H
= 79 H
* When the measured temperature fluctuates
between two values, take lower one (if
temperature fluctuates between 7A H and
79 H, take 79 H).
6
Press the POWER button and write the temperature
setting into the EEPROM.
2. Method for making settings other than the reference
temperature
1
Install the MD main PWB in the mechanism, and connect
it to the main unit.
2
Enter the test mode as shown on page 24, and insert a
disc.
"AUTO AJST"
3
Press the CD PLAY button seven times.
"EEPROM SET"
4
Set the value according to the EEPROM DATA LIST
using the VOLUME UP/DOWN button.
5
Press the POWER button, and the settings will be written
into the EEPROM.
6
Enter the test mode again, perform an "AUTO YOBI
adjustment", and write the results into the EEPROM.
