• Adjustment Procedure

a) Insert the SP Test Tape and play. b) Connect the CH1 of the oscilloscope to the H/SW(W373, W374) and CH2 to the Video Out for the VCR. c) Trigger the mixed Combo V ideo Signal of CH2 to the CH1 H/SW(W373, W374), and then check the dis-

tance (time difference), which is from the selected A(B) Head point of the H/SW(W373, W374) signal to the starting point of the vertical synchronized signal, to 6.5H ± 0.5H (412µs, 1H=63µs). Note - Press FRONT CH UP KEY and FRONT PLAYKEY on Deck playback, and it goes in to ATR PRE-

SET. after the SP Test Tape is inserted.

• PG Adjustment Method

a-1) Payback the SP standard tape b-2) Press the “O” key on the Remote controller and the “PLAY” key on the Front Panel the same time,

then it goes in to Tracking initial mode. c-3) Repeat the above step(No.b-2), then it finishes the PG adjusting automatically. d-4) Stop the playback, then it goes out to PG adjusting mode after mony the PG data.
