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.
3.6.2 Horizontal geometry adjustment
1. Input a PAL crosshatch pattern signal to RF input.
2. Enter P-Mode, press key “2” to select horizontal geometry adjustment. (The OSD
menu for this adjustment as below table 3.6.2. For NTSC signal, the “-50” will be replaced
with “-60”.)
3. Adjust the value of the corresponding item to make the horizontal geometry of the
pattern look good.
4. Apply NTSC signal to adjust these value for NTSC horizontal geometry.

Note:
1. For NTSC signal, the “-50” will be replaced with “-60”.
2. For NTSC signal, only the “HCEN-60” and “HSIZE-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 now the geometry of NTSC signal is look good, it not needed to adjust the
geometry of NTSC signal any more.
