❚❚ Before Use
The lens is retractable and must be extended before use. Rotate
the zoom ring as shown until the lens clicks into the extended
position. Pictures can only be taken when the focal length mark
points to positions between 50 and 250 on the focal length
scale.
To retract the lens, rotate the zoom ring in the opposite
direction, stopping when you reach the (I) position on the focal
length scale.
If the camera is turned on with the lens retracted, a warning will
be displayed. Extend the lens before use.
