SAMSUNG DCS 70
INSTALLATION MANUAL
A square at the right hand end of the silkscreen HYB outline on the 3TRK and 6TRK cards
marks the pin 1 position.
A black triangle is printed on one side of the PRS and MPD hybrids. The triangle marks pin
1 of the hybrid.
The 3TRK and 6TRK boards must be modified before they can be used with PRS hybrids.
The modification involves soldering a wire link across the decoupling capacitors used for
MPD so that the PRS hybrid is connected directly to the line.
