LOADING OF MERCURY BATTERY CELLS

The compound CdS meter of the KONICA AUTOREFLEX A takes two 1.3V mercury battery cells as its electric source. Wipe the
mercury battery cells, accessories for camera, with a piece of dry and clean cloth and put them into the mercury battery chamber.

1 Turn the cover of the Mercury Battery Chamber 27 counterclockwise with a coin and detach it from the chamber.

2 Insert the two cells into the mercury battery chamber, the "+" side up, according to the figure printed on the seal inside the

chamber. After the cells have been put into position, put the cover on the chamber and screw it tightly.

Mercury Battery Cells

For the mercury battery, it is recommendable to use 1.3V battery, Mallory PX-675 or Eveready EPX-675.
Since there are various batteries which resemble the above, but are of a different voltage than that required, caution should be
