    Hearing Loop Installation Ensure all hearing loop signage is displayed clearly. Option 1: IL-AE96 Window Mount Hearing Loop The IL-AE96 Window Mount Hearing Loop should be installed indoors on the staff side. 1. Determine the location of the hearing loop aerial on the glass barrier. Make sure to place it directly in front of where a customer will stand. It is recommended that the unit is placed on the bottom corners of the glass barrier for optimal performance. Do not exceed 2 feet above the average standing customer. 2. Clean the area with a glass cleaner and thoroughly wipe dry. 3. Remove the liner on the blue sheet with a faint outline of the international hearing loop signage to expose the adhesive backing. Please note that both sheets are not solid blue. 4. Carefully attach the sheet on the glass barrier with the international hearing loop signage facing the customer. Slowly apply to glass barrier while smoothing out air bubbles with straight-edged tool.
  • Page 19 6. Carefully apply the hearing loop aerial with attached cable to the adhesive on the solid blue sheet. Ensure the cable is at the edge of the sheet, and the wire is coming from the back side of the aerial when applied. 7. Attach the solid blue sheet with hearing loop aerial to the sheet attached to the glass barrier. Slowly apply while smoothing out air bubbles with straight-edged tool.
  • Page 20 Option 2: Under the Counter Hearing Loop 1. The aerial should be fixed under the desk or counter centrally on the customer side, one half mounted horizontally under the counter and the other half mounted vertically, facing the customer (see A in the diagram below). Position the aerial under the counter using either the provided P-clips or another fixing method of 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. 2. Route the cabling neatly to the amplifier location on the staff side 3. Plug the loop’s connector into the “Loop” port on the back of the amplifier.
