Eeprom Writing Procedure - Sharp MD-X60H Service Manual

EEPROM (IC1402) writing procedure
1. Procedure to replace EEPROM and to write the initial
value of microcomputer in EEPROM
(1) Replace EEPROM.
(2) Refer to the latest EEPROM data list.
(3) Hold down the button and MD PLAY button, and press the
POWER button to enter the test mode.
(4) Indication of version.
[ t s m e ]
(5) Set the temperature reference value.
(Refer to "Temperature reference setting procedure".)
(6) Press the CD PLAY key 7 times.
[ E E P R O M S E T ]
(7) Perform the operation shown in the "EEPROM setting mode
chart", compare the indication with the EEPROM data list, and
make a setting according to the EEPROM data list, using [JOG
DIAL UP] or [JOG DIAL DOWN]
(8) The setting must conform to the EEPROM data list.
(9) Turn off power supply to write in EEPROM.
2. Temperature reference value setting procedure
(to be executed at room temperature within 21 to 29°C)
(1) Test mode eject state
Ambient temperature
+ 21.0 °C ~ + 22.3 °C
+ 22.3 °C < + 26.3 °C
+ 26.3 °C < + 29.0 °C
An example: When ambient temperature is 22°C and meadured
temperature is 73H
Temperature setting = 73 H - 01 H
* When the measured temperature fluctuates between
two values, take lower one (if temperature fluctuates
between 73H and 72H, take 72H).
(2) Press the CD PLAY button 7 times.

: Measured temperature,
(6) Set temperature to the value determined above, using
[JOG DIAL UP] or [JOG DIAL DOWN]
(7) Press the MD STOP button.

(8) Write in EEPROM by pressing ENTER button
• Temperature code check
The temperature code is read after automatic adjustment. If it is within the range shown below, the adjustment is OK.
Ambient temperature
+ 19.6 °C ~ + 30.7 °C
+ 8.7 °C ~ + 19.6 °C
