NOTE: Since the SIT chart (UKOG-0280FCZZ or UKOG-0280FC

Z1) is easily discolored by sunlight (especially ultraviolet
rays) and humidity and temperature, put it in a bag (such
as a dark file) and store in a dark place of low temperature
and low humidity.

 

1)

Check to insure that there is no dirt or dust on the DSPF scan-
