2. CUE/REV Check
1) Play the tracking alignment tape (XH2-1A1) (Ref. No. J-18)
back and enter the REV mode. Confirm that pitches between
peaks of RF waveform are equally spaced. (Refer to Fig. 6-2-
42.)
If pitches between peaks of RF waveform are not equal, perform
sections "2-4-2. Tracking Adjustment" and "2-4-4. TG7 Guide
Adjustment".
2) Enter the CUE mode. Confirm that pitches between peaks of
RF waveform are equally spaced. (Refer to Fig. 6-2-42.) If
