Refit the housing using the screws previously removed. 9. Avoid loose or trailing cables. Use trunking or to prevent trip hazards or units being tugged from their position. 14. Route all the cabling neatly to the amplifier location on the staff side. 8 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 XB XC 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. 9 Amplifier Setup Overview of Front Panel Buttons On/Off Settings Volume In (Customer/Visitor to Staff) Increase and decrease Setup Volume Out (Staff to Customer/Visitor) Increase and decrease 1. Connect all green plugs to the back of the amplifier, following the locations printed above the sockets (see page 4). 2. Power on the amplifier by pressing the On/Off button. 3. When powered and in normal operational mode the amplifier will display Volume In LED 1 and Volume Out LED 1 as steady green. 4. When the amplifier is switched off, all audio is muted and none of the LEDs are illuminated. Pressing any button will turn the amplifier on again. 5. Adjust Volume In and Volume Out to a comfortable level. 6. Press and hold the Volume In (+) or (-) buttons to increase or decrease the level. The corresponding LED bar will show the volume setting. 6. Ensure the mouse microphones are placed as close to their intended users as possible. 7. Check the amplifier is fully functional by ensuring the red `fault' light is NOT showing on the front. 8. The Amplifier is now set up. Our Window Intercom System amplifiers are pre-set to volume levels suitable for nearly all users. Should you need to adjust the Maximum Volume, Ducking or Hearing Loop levels outside of the pre-set amplifier parameters, use Engineer's Mode (see page 13). 10 Fault Diagnosis LEDs · Volume In LED 8 will stay red if there is a fault with the staff microphone. · Volume Out LED 8 will stay red if there is a fault with the customer/visitor microphone. · Volume In LED 8 will flash red if there is a fault with the loop (e.g. a broken aerial). Factory Default Settings To return the amplifier to the factory default settings: 1. Unplug the power supply and then reconnect it. 2. The LED indicators will show a light pattern in the "Vol In" column. This indicates the firmware revision. This will be followed by a green light at the bottom of each column. 3. Within 20 seconds, press the On/Off button and Volume In (-) button together, then release them. 4. The "Vol In" column will again indicate the firmware revision. This indicates that the settings have been restored. 11 Troubleshooting Symptom Possible Fault There is no power 1) Power jack not plugged in or faulty. detected through the 2) Plug fuse has blown. amplifier (and there is power at the socket). 3) Faulty power supply unit.
