5. Electrical Adjustment List
(Adjustment Menu Screen) : During normal servicing, check the applicable items, and adjust them if necessary.
In the adjustment using the monoscope signal, if a monoscope signal generator is not available, use the video signals that
either the test tape TTV-06T (PAL 625 lines) or TTV-N06T (NTSC 525 lines) is played back on the VCR. At that time, be
careful of the color system of the input signal (VCR output signal).
This manual shows the two types of the adjustment values of the screen size when a monoscope signal (PAL and NTSC)
is used. One is the value that is measured using the Shibasoku monoscope signal. The other is the value when the screen size
is converted into a percentage.
When you are going to use the monoscope other than that of Shibasoklu, be sure to let it have a compatibility by converting the
scale reading into a percentage.
For the simplified adjustment value of the screen size using a pattern generator, this manual shows the value when either
Leader LCG-404 (PAL/SECAM) or the LCG-401 (NTSC) is used.
