EMG detail information <1>

The status (electrical operation mode) of the VCR and the sta-
tus (mechanism operation mode/sensor information) of the
mechanism in the latest EMG can be confirmed based on the
figure in EMG detail information <1> .

[FDP/OSD display]

* 1  : * 2  : 34

 * 1 : Deck operation mode at the moment of EMG
 * 2 : Mechanism operation mode at the moment of EMG
 3– : Mechanism sensor information at the moment of EMG
 –4 : Mechanism mode position at the moment of EMG

Note:
•

For EMG detailed information <1>, the content of the code
that is shown on the FDP (or OSD) differs depending on
the parts number of the system control microprocessor
(IC3001) of the VCR. The system control microprocessor
parts number starts with two letters, refer these to the cor-
responding table.
