Eeprom Writing Procedure - Sharp MD-C2 Service Manual

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 21.
"EJECT"
(4) Press the X-BASS button.
"TEMP "
:Measured temperature,
(5) Find the temperature correction value for the current ambient
temperature on the following table. Adjust the temperature
correction value using the jog dial.
Ambient temperature
+ 21.0 °C ~ + 23.2 °C
+ 23.3 °C < + 26.8 °C
+ 26.9 °C < + 29.0 °C
An example: When ambient temperature is 22°C and measured
temperature is 7AH
Temperature setting = 7A H - 01 H
* When the measured temperature fluctuates between
two values, take lower one (if temperature fluctuates
between 7AH and 79H, take 79H).
(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 21, and insert a disc.
"AUTO YOBI"
(3) Press the PLAY MODE button.
"EEPROM SET"
(4) Selection mode using the MD1 PLAY key.
(5) Selected using the SURROUND key.
(6) Determined by the MD1 PLAY key.
(7) Using the jog dial, adjust the settings as shown in the "List of the
EEPROM contents".
(8) Press the POWER button, and the settings will be written into
the EEPROM.
(9) Enter the test mode again, perform an "AUTO YOBI", and write
its results into the EEPROM.
