[1] Measurement, calculation and setting procedure.
1
Set the TEST mode.
2
Activate the “Temp” menu in the “EEPROM” mode.
• In the test mode stop state, press the MENU button,
SKIP-DOWN button (three times), and PLAY button
(twice) in this order.
• “TM$$%%” appears. ($$ = temperature code, %% =
temperature reference value)
3
“TPin##” will appear when pressing the SKIP-UP button
once. (## = TEMP input AD value)
4
Calculate the temperature correction value by referring
to the ambient temperature and the “Temperature
measurement value correction table”.
5
Calculate the temperature reference value according to
the formula below.
• Temperature reference value = Microcomputer TEMP input
AD value + Temperature correction value
6
Press the SKIP-DOWN button once to display “TM$$%%”.
Press the VOLUME –/+ button to set “%%” to the value
calculated in step
5
.
7
Check if the temperature code ($$) is the same as in the
“Temperature measurement value correction table”

Er-MD (**)
** = 80
“Er-MD 80” appears when EEPROM data cannot be read correctly
(inconsistency of data and the checksum results).
EEPROM or communication paths including the microcomputer
may be defective.
When you change EEPROM, reset data by referring to the service
manual.
** = 41
“Er-MD41” appears when writing U-TOC fails. (Only recorders)
(Reading of the written data reveals errors.)
The record head, the recording signal generator circuit including
system LSI or the pickup laser may be defective.
