1. Playback WS-48B (tape center) in the FWD state.
2. Adjsut the volume in CAPSTAN/REEL motor (M301) so that
the frequency counter reading becomes 3,000 Hz.
Specified Value: 2,910 to 3,090 Hz
3. Confirm that the frequency at the beginning and that at the
end of tape winding are between 2,940 to 3,060 Hz.
