*Notes:

1. For NTSC signal, the “-50” will replace with “-60”.

2. For NTSC signal, only the “VCEN-60” and “VSIZE-60” items need the adjustment,

the other items use the same data as PAL signal.

3. On producing, please use the “AUTO OFFSET” (On page “2”) function to easy the

geometry adjustment of NTSC signal. When finished the PAL signal geometry adjustment,

press “2” key to enter page “2” to select “AUTO OFFSET” item, press “” key to active the

automatic offset function. Then the geometry adjustment of NTSC signal will finish

automated. If the geometry of NTSC signal is look good, you don’t need to adjust the

geometry of NTSC signal any more.
