Changing the Focusing Screen
1. Remove the lens.
2. Pull the Focusing Screen Release lever A
forward, as illustrated, with the tweezers to let
the Focusing Screen down.
Caution
Since the Focusing Screens' surfaces are soft and easily damaged, handle them
carefully.
Never touch the surface with bare fingers. Should dust settle on it, merely blow away
by using a blower.
If the Focusing Screen needs cleaning, send it to the nearest authorized Mamiya
service center. Do not attempt to clean the surface of the Focusing Screen, as it is
very delicate.
3. Remove the Focusing Screen from the
Focusing Screen Frame by grasping the tab on
the edge of the screen with tweezers as
illustrated.
Do not touch and damage the mirror in any way.
4. When installing the screen, pinch the tab of
the screen with tweezers, and put the screen on
the screen frame.
5. Push up the screen frame using the tweezers
until hearing a clicking sound. The screen is
now properly installed.
Never press down on other parts as this will
affect the focus function.
