• When the FORWARD button is pressed in the REC mode target
address is displayed, the digit of address specified by the REC
button is set to +1h. (0 to F)
• When the REVERSE button is pressed in the REC mode target
address is displayed, the digit of address specified by the REC
button is set to -1h. (0 to F)
* When the FORWARD/REVERSE button is held down, the setting
changes continuously, one cycle being 100 ms.
• When the /– button is pressed in the REC mode or
continuous record mode, the laser record power changes.

“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.
