Precautions taken before adjustment

• If a mono-scope signal oscillator is not available for the adjustment that requires mono-scope signals, use the image signals of test tapes,

TTV-06T (PAL 625 LINE) and TTV-N06T (NTSC 525 LINE) played by VCR.  Be sure the color system for input signal (VCR output

signal).

• In this manual, the values measured with SHIBASOKU-made mono-scope and the percentages of screen size are used as the adjustment

values of screen size measured with a mono-scope (PAL/NTSC).  When a different model is used, calculate measured values in percentage.

• In this manual, the values measured with LEADER-made LCG-404 (PAL/SECAM) and LCG-401 (NTSC) are used as the simple

adjustment values of screen size measured with a pattern generator.
