MOUNTING THE LENS INSERTING THE BATTERIES
Mount the Lens.
Align the red dots on the lens flange and the body
mount ring. Turn the lens clockwise until the lens
release button springs up and you will hear posi-
tive "click".
Lens Removal
To detach the lens, press
down on the lens release
button and turn the lens
counter-clockwise. Always
attach the front and rear
lens caps when the lens is
removed from the body to
prevent any possibility of
damage.
Insert two 1.5V silver oxide batteries SR44
(Eveready EPX-76 or equivalents) into the bat-
tery chamber.
CAUTION: Batteries should be always replaced
as a pair. If battery polarity is incorrect, the cam-
era does not function.
