The camera mounting screw hole is for mounting the
camera onto a mounting bracket. The camera is origi-
nally designed to be mounted from the bottom, howev-
er, a top-mounting type is also available. To mount from
the top, remove the mount adapter from the bottom of
the camera by removing two fixing screws. Attach the
mount adapter to the top as shown in the diagram, then
mount the camera on the mounting bracket. Make sure
that two original screws are used when mounting the
mount adapter; longer type screws may damage inner
components, too shorter type screws may cause the
camera drop.
