Camera cannot be opened in such case.
Opening the camera head of G2 cameras revision 1 and 2
The blade shutter rotates 180° between individual snapshots, but only the initial
position is safe for removing the camera cover in the case of camera revisions 1
and 2, because the shutter can interfere with the filter wheel drive if it remains
in the second position and the camera head is opened. To make sure the shutter
is in the initial state, plug the camera to the computer and let it to initialize prior
to opening the camera head. Note the initialization is performed only if the
camera is connected to the computer (with properly installed driver) through
USB cable. Just powering on the camera is not enough.
Warning:
Shutter can be damaged while removing the camera cover if not in proper
position.
After removing the screws carefully turn the camera head by the telescope
adapter upward. Gently pull the front part of the case. Notice there are two
cables, connecting the filter wheel motor and the filter position optical bar,
plugged into the electronics board. It is not necessary to unplug these cables to
change filters, but if you unplug them, take care to connect them again in the
proper orientation!
