1. Connect 0C voltmeter as shown in Fig. 4-9.
2. Playing in REV direction, magnetic tape portion of
test tape consists of efementes in Fig. 4-10(MTT-5551
tape, etc.) adjust R57 so that a voltage of 3.0 ¥ is
obtained at TP.5(+), TP.6{-).
3. In FHD play, similarty adjust R59 for obtaining a
voltage of 2.8 V.
4. Re-check that voltage is REV play does not change
from 3.0 V. ;
5. Set AUTO REVERSE switch in (2D position, then play
tape in FHD ode from point A in Fig.4-10. Check that
tape motion changes in REV play mode at point B, then
changes is FWD play mode at pont A.
