<Example 2> E : - -
(2) Transmit the code "59" from the Jig RCU again.
The FDP shows the EMG detail information <1> in the form
of " *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
(3) Transmit the code "59" from the Jig RCU once again.
The FDP shows the EMG detail information <2> in the form
of " *5 : *6 : *7 ".
*5 : Type of the cassette tape in use <1> .
*6 : Winding position of the cassette tape in use
*7 : Type of the cassette tape in use <2> (Winding area)

The FDP shows the EMG detail information <3> in the form
of "*8 : *9 : *10".
*8 : Previous deck operation mode at the moment of EMG
*9 : The deck operation mode of the one before the last at
the moment of EMG
*10: The deck operation mode of the one prior to one
above at the moment of EMG
(5) Transmit the code "59" from the Jig RCU once again to re-
set the display.
