software. If you can only view ONE page, then your particular software doesn't
support multi-page TIF files. You may need to "Save As...." this file
to disk and manually load it in to the Imaging software that supports

Overview
Designed specifically for displaying video images from sources such as video recorders and camcorders, door security systems, CCD cameras or even hand-held games, Citizen's range of liquid crystal video modules all make use of "Chip-On-Glass" ( C.O.G. ) technology providing the following advantages:-
High contrast image
Clearer, brighter colours
Excellent picture definition
Compact, lightweight and robust design
Together with the combination of C.O.G. technology, the fast fluid liquid crystal and low resistivity I.T.O. (Indium-Tin Oxide) electrodes ensure that the image on the display is high quality and high contrast making it extremely clear and easy to see.
