Pentax Program Plus User Manual

DIOPTER ADJUSTMENT, CHANGING BACK COVER
Correction lenses M are available for the viewfinder. There are
8 auxiliary M lenses: -5, -4, -3, -2, -1, +1, +2 and +3D. Choose
the one that suits your eye, and put it in the eyepiece accessory
slots as illustrated. Before buying one, try it for yourself with
the lens actually attached to your camera.
Changing the back cover
The back cover must be removed from your camera to use such
accessories as the Dial Data ME or Digital Data M data-imprinting
devices. Open the back cover, and pull slightly while pushing
down the back cover release pin to disengage the locking
mechanism. Then the cover can be easily removed. When
reattaching it, first put the lower back-cover-release lug into
position, then match the upper lug with the release pin pushed
downward. Release the pin to attach the back to camera body.
