There is nothing that can be done with a telephone except making calls, an activity which is prohibited on Shabbos. Severe muktzeh may not be moved, even if the place which it occupies is needed for a permitted activity. It follows, therefore, that the telephone, etc., cannot just be picked up and removed from the bed or chair. Although theoretically this option can be exercised, it has virtually no practical application. While this particular violation does not apply to a camera, it is still not practical to shove or kick a camera from the bed to the floor, since doing so would likely ruin the camera.
Indirect movement means using a non-muktzeh item to move a muktzeh item.
For instance, indirectly moving a camera off the bed or chair in order to protect it, i.e., for the sake of the camera, is prohibited. This leniency, however, is not agreed upon by all poskim. In his opinion, indirect movement is permitted only when the permitted item is being moved for its own sake, and the muktzeh is inadvertently being carried along with it. While the laws of bosis are complicated, the basic rule is that the bosis cannot be moved even if somehow the muktzeh item is no longer on it. The blanket and bed in our case, however, do not become a bosis.
