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.

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 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”.

Note:

In the case of the "HD*” microprocessor, as the display is always "-7” at any intermediate position between modes, the position of transitory EMG may sometimes not be lo- cated.
