 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 and 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 38.
"EJECT"
(4) Press the X-BASS 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 JOG UP/DOWN knob.
An example: When ambient temperature is 22
°
C and measured
temperature is 7AH
Temperature setting = 7A H - 01 H
        = 79 H
* When the measured temperature fluctuates between
   two values, take lower one (if temperature fluctuates
 between 7AH and 79H, take 79H).
(6) Press the MENU button and write the temperature setting into
the EEPROM.

EEPROM WRITING PROCEDURE
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 38, and insert a disc.
"AUTO AJST"
(3) Press the EQALIZER button seven times.
"EEPROM SET"
(4) Set the value according to the EEPROM DATA LIST using the
JOG knob.
(5) Press the MENE 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.
