Hearing Loop Installation The aerial should be fixed under the desk-top or counter centrally on the custome or visitor side, one half mounted horizontally under the counter and the other half mounted vertically, facing the customer/visitor (as in the first scenario below). Position the aerial under the counter using either the provided P-clips or another fixing method of your choice. See the diagram below for recommended positioning. A is the optimum layout for a counter hearing loop. B and C are acceptable only if A is not possible and the layout is aligned so that the magnetic field will be directed towards user’s head heights. Ensure all hearing loop signage is displayed clearly. -
