mismeasurement, use the ENTER key to toggle between [On] and [Off]. (for interlaced images,
1 frame contains 2 fields).
ReadAMDS AMDS = automatic mode detection & synchronization
Duringthe installation of a file with LOAD, the system automatically measuredthe horizontal period,
thetotal vertical lines and the interlaced mode. Whenselecting Read AMDS, the system remeasures
the above indicated items.

Fieldpolarity Thefieldpolarity function is used for interlaced images. Bothrasters of the image could be shifted in a
wrongway (double lines are visible in the i mage). This can be corrected by forcing the field polarity to
[neg]or [pos]. Usethe ENTER key to toggle between [pos] and [neg].
Fieldselect Default [both]
Thefield select is only used for interlaced images. Oneframe of an interlaced image contains two
fields,an even and an odd field. Thechoice exists to project [both] fields on the screen or only the
[even]or [odd] field. This can be useful for 3D projection. Use the ENTER key to toggle between
[both], [even] and [odd].
