always "-7" at any intermediate position between modes,
the position of transitory EMG may sometimes not be lo-
cated.
1.6.5 EMG detail information <2>
The type of the cassette tape and the cassette tape winding po-
sition can be confirmed based on the figure in EMG detail infor-
mation <2> .

Note:
• EMG detail information <2> is the reference information
stored using the remaining tape detection function of the
cassette tape. As a result, it may not identify cassette cor-
rectly when a special cassette tape is used or when the
tape has variable thickness.

F1 C cassette, thick tape/thin tape (TC-10 to TC-40) not classified
Notes:
<1>
• Cassette tape type 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 identi-
fication, the cassette tape type may not be able to be identified.
• If other value than those listed in the above table is displayed,
the cassette tape type is not identified.
* 6 : Cassette tape winding position
The cassette tape winding position at the moment of EMG is
displayed 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" : Tape position not identified
