Note:
• In the case of the "HD*" microprocessor, as the dis play
is always "-7" at any intermediate position between
modes, the position of transitory EMG may sometimes
not be located.
2.8.5 EMG detail information <2>
The type of the cas sette tape and the cassette tape winding po-
sition can be confirmed based on the figure in EMG detail infor-
mation<2>.
[FDP /OS D dis play]
*5 : *6 : *7
* 5 : Type of the cas sette tape in use <1>
* 6 : Winding pos ition of the cas sette tape in use
* 7 : Type of the cas sette tape in use <2> (Winding area)
Note:
• EMG detail information <2> is the reference informa-
tions tored using the remaining tape detection function
of the cassette tape. As a result, it may not identify cas-
sette correctly when a special cassette tape is used or
when the tape has variable thickness.

Notes:
• Cassette tape type <1> is identified a few times during
mode transition and the identification count is variable
depending on the cassette tape type. If an EMG occurs
in the middle of identification, the cassette tape type
may not be able to be identified.
• If other value than those listed in the above table is dis-
played, the cassette tape type is not identified.
*6 : Cassette tape winding position
The cassette tape winding position at the moment of EMG is dis-
played by dividing the entire tape (from the beginning to the end)
in 22 sections using a hex number from "00" to "15".
"00"
: End of winding
"15"
: Beginning of winding
"FF or - -" : Tape position not identified

Note:

are typical values with representative cassette tapes.
2.8.6 EMG detail information <3>
Three deck operation modes preceding the deck operation mode
in which the EMG occurs may be confirmed based on the figures
in the EMG information detail <3>. For the contents of the dis-
played information, see the table "Deck operation mode" in sec-
tion "2.8.4 EMG detail information <1>".
