only when the batteries are properly inserted.

^ on the tab in the chamber.

** chamber (see the following page for proper loading), attach
the lower battery chamber cover by turning the knob to the right.

lent to IVIallory RM-625R, Eveready E625N, GE #625, National
M-ID or Toshiba TH-MC.

with a dry cloth. Unclean poles may cause corrosion and damage
the contact points of the camera.

tion. Otherwise, the electric eye will not function properly.
