Despite the recommendation to not use ceiling mounting of the RF9, there are oc-
casions when this could be used for improving the radio performance.
For example when doors are placed in areas consisting of several floors with
"open" stairs and the doors are closed to each other.
Other wall-mounted RF9 can of course also be used in conjunction with this special
ceiling mounting.
