Panasonic RS-TR252 - Manual (Page 14)

Selection of cassette tapes
Cassette tapes exceeding 90 minutes
These tapes are handy for their long playback and recording time
but be careful about repeatedly stopping and starting, rewinding
and fast forwarding these tapes in short intervals as they are thin,
tend to stretch and may become entangled in deck mechanism.
Endiess tapes
If the proper operating method is not followed, the tape will
become wrapped around the rotating parts. Be absolutely sure to
read the directions for use accompanying the tape.
Since this unit has an auto reverse capability, the use of tapes
which support this capability is recommended.
Fe-Cr tapes (TYPE m)
The high frequency range will be emphasized, and it will not be
possible to obtain a fiat frequency response.
Metal tape without detection holes in the cassette
Recordings will be very distorted. (However, there will be no pro­
blem with playback.)
