2.6Attaching the back

The P+ back is fully integrated with the camera body and is a part of the whole camera system.

When no cassette is attached to the Phase One 645AF camera house the mirror is up and the shutter is open. This is the correct position when no back is attached.

When attaching the P+ back to the camera body the shutter will close and the mirror comes down. It is important to ensure that the bottom part of the P+ back is pressed well into the locking mechanism on the camera back before the upper locking mechanism is pressed together.

Failure to do this can cause an error with the camera body. The error is a state of continuously opening and closing the shutter. If this occurs, remove the P+ back.

Please be aware that the shutter should be in the correct starting position (shutter open), if this is not the case, attach and remove the P+ back again to make sure that the camera body gets in the correct starting position.
