1. CONFIRMATION AND ADJUSTMENT
Read the following NOTES before starting work.
Place an object which weighs between 450g~500g onthe Cassette Tape to keep it steady when you want to
make the tape run without the Cassette Holder. (Do notplace an object which weighs over 500g.)When you activate the deck without the CassetteHolder, short circuit between TP1001 and TP1002.(Refer to ELECTRICAL ADJUSTMENT PARTSLOCATION GUIDE) In this condition the BOT/EOT/ReelSensor will not function.

Tape Running Mechanism is adjusted precisely at thefactory. Adjustment is not necessary as usual. When you
replace the parts of the tape running mechanism becauseof long term usage or failure, the confirmation andadjustment are necessary.

Playback the VHS Alignment Tape (JG001C or JG001E).(Refer to SERVICING FIXTURE AND TOOLS)Connect CH-1 of the oscilloscope to TP4002(Envelope)and CH-2 to TP4001(SW Pulse).Press and hold the TRACKING-AUTO button on theremote control more than 2 seconds to set tracking tocenter.Trigger with SW Pulse and observe the envelope. (Refer
to Fig. 2-1-A)When observing the envelope, adjust the Adjusting Driver(JG005) slightly until the envelope will be flat.Even if you press the Tracking Button, adjust so thatflatness is not moved so much.Adjust so that the A : B ratio is better than 3 : 2 as shownin Fig. 2-1-B, even if you press the Tracking Button tomove the envelope (The envelope waveform will begin todecrease when you press the Tracking Button).Adjust the PG shifter during playback.(Refer to the ELECTRICAL ADJUSTMENTS)
