6. REC Mode
• When the STOP button is pressed while the REC menu appears, or
in the REC mode or continuous record mode, the mode changes to
the TEST mode stop state.
• Whenever the DISP button is pressed in the REC menu, the target
address changes as follows.
0032 → 03C0 → 0700 → 08A0 → 0950 → 0032 → •••
When the PLAY button is pressed while a target address is dis-
played, continuous playback is performed after searching that
address.
• Whenever the REC button is pressed in the REC mode target
address is displayed, the digit which is changed by the VOLUME +/
– button changes as follows.
0032 → 0032 → 0032 → 0032 → •••
• 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.

"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.
• When the VOLUME +/– button is pressed in the REC mode or

8. E_DATA display Mode
• Reversing when REVERSE button is pressed.
• When the STOP button is pressed while the error data indication
menu appears or during error data indication, the mode changes to
the TEST mode stop state.
• Error data 0 is the latest error.
• Error which occurred in the TEST mode is also stored in the memory.
• When the DISP button is pressed while the error data indication
menu appears, the error data is initialized.

(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.
