• EMG detail 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.

Display Cassette Tape Type
00 Cassette type not identified
16 Large reel/small reel (T-0 to T-15/T-130 to T-210) not classified
82 Small reel, thick tape (T-120) identified/thin tape (T-140) identified
84 Large reel (T-0 to T-60) identified
92 Small reel, thick tape (T-130) identified/thin tape (T-160 to T-210) identified
93 Small reel, thick tape/C cassette (T-0 to T-100/C cassette) not classified
C3 Small reel, thick tape/C cassette (T-0 to T-100/C cassette) being classified
D3 Small reel, thick tape/C cassette (T-0 to T-100/C cassette) being classified
E1 C cassette, thick tape (TC-10 to TC-20) identified
E2 Small reel, thick tape (T-0 to T-100) identified
E9 C cassette, thin tape (TC-30 to TC-40) identified
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 tran-
sition and the identification count is variable depending on the
cassette tape type. If an EMG occurs in the middle of identifi-
cation, 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.

: 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
