Your is the original model. The dark button is for low light levels, and
activates the scale on the top (from 1 to 12), and the light one
activates the scale on the bottom (from 11 to 21). The meter was
originally intended for mercury cells, not available now. You can use SR44
cells, but the meter should be recalibrated (you can do it yourself, if
you are handy and have a precise light meter or a camera with it) , or an
adapter must be used to lower the voltage from 1.55 volts to 1.35 volts.
There are some information about that in internet. Google for "mercury
cell replacement". I think also the manual in english can be downloaded
from some place. Hope this helps.
