CUE/REV Check
1) Play back the tracking alignment tape (XH 2-1) (Ref. No. J-5).
2) Establish the CUE mode. Confirm that the pitches between the
peaks of the RF waveform are equally spaced. Also confirm
that the RF waveform amplitude at entrance side (B) and exit
side (C) is 50% or more respectively, when taking the amplitude
(A) in the CUE or REV mode as 100%.
3) Establish the REV mode. Confirm that the pitches between the
peaks of the RF waveform are equally spaced. Also confirm
that the RF waveform amplitude at entrance side (B) and exit
side (C) is 50% or more respectively.

Rise-up Check
1) Play back the tracking alignment tape (XH 2-1) (Ref. No. J-5).
2) Change the modes from CUE mode to FWD. Confirm that the
RF waveform rises up within two seconds when the mode is
changed from CUE mode to FWD.
3) Change the modes from REV mode (two seconds or more of
REV and to the FWD within five seconds) to FWD. Confirm
that the RF waveform rises up within two seconds when the
mode is changed from REV mode to FWD.
4) Change the modes from STOP mode to FWD. Confirm that
the RF waveform rises up within two seconds when the mode
is changed from STOP mode to FWD.
