1.3.5 EMG detail information <1>
The status (electrical operation mode) of the VCR and the status
(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 display (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 correspond-
ing table.
* 1 : Deck operation mode
