1. Place the sta microphone on the sta side of the counter top, ensuring
that it does not cause an obstruction and is as close to sta as possible.
2. Place the amplier under the sta counter, ensuring that it will not
obstruct sta when they are sitting.
3. Mark the 4 xing points for the amplier under the counter.
4. Drill and x the amplier in place using the supplied screws.
5. Use the cable management hole to run the sta microphone cable back
to the amplier. If there is not already a cable management hole, one will

Hearing Loop Installation
The aerial should be xed under the desk-top or counter centrally on the
customer side, one half mounted horizontally under the counter and the other
half mounted vertically, facing the customer (as in the rst scenario below).
Position the aerial under the counter using either the provided P-clips
or another xing method of your choice. See the diagram below for
recommended positioning.
Ensure all hearing loop signage is displayed clearly.

Once you have followed the above steps:
1. Ensure sta microphone is no more than
300mm away from the sta member when
sitting.
2. Check amplier is fully functional by ensuring
the red ‘fault’ light is NOT showing on the front.
Initial Set-Up
To achieve the best possible performance, we recommend following the
below steps:
1. Ensure the customer and sta volumes are turned completely down
2. Adjust sta (Volume In) volume to a comfortable level
3. Increase customer (Volume Out) volume until feedback is heard
4. Decrease customer (Volume Out) volume until feedback is just eliminated
Factory Default Settings
To return to the factory default settings:
1. Unplug the power supply and then reconnect it.
2. Press the “On/O” button and Volume In - button together, then release.
3. The status LED bar graph will show a xed pattern of LEDs indicating the
rmware revision number, followed by all LEDs illuminated - this
indicates that the default settings have been restored.
If there is insuicient volume, enter Engineer Mode and raise max volume
settings, then exit Engineer Mode and repeat initial setup.
The system is now ready to use. Speak into the microphone to converse easily
through glass.

Sta or customer microphone fault.
2) Red LED comes on after speech:
Induction loop fault.
1) Induction loop or microphone is
disconnected.
2) Faulty loop tester.

connections and, if possible, check the
hearing device with a known working
hearing loop.
2) Ensure loop tester has a new set of
batteries.
1) Unscreened or poorly earthed
third party equipment is being used
in close proximity.
2) Internal volume gain set to high.
3) Incorrect power supply being
used.
1) Switch o any third party equipment to
identify the source of interference.
2) Access the amplier Engineer Mode to
adjust the internal settings.
3) Ensure that our grounded power supply
unit is connected.
