2) Red LED comes on after speech:Inductionloopfault.

1) Ensure microphone is wired correctlyandfirmlypluggedin. Try alternative microphone to ensure portisworking.

2) Ensure induction loop connector is wiredcorrectlyandfirmlypluggedin.

I can’t hear audio through the induction loop.

1) Induction loop or microphone is disconnected.

2)Looptesterhasafault.

1 ) Check instructions for correct connections and, if possible, check the hearing device with a known workinghearingloop.

2) Ensure loop tester has a new set ofbatteries.

I can hear interference through speakers (buzzing / whistling / hissing).

1) Unscreened or poorly earthed third party equipment is being used incloseproximity.

2)Internalvolumegainsettohigh. 3) Incorrect power supply being used.

1)Switchoffanythirdparty equipment to identify the source of interference.

2)Accesstheamplifierengineersmodetoadjusttheinternalsettings. 3) Ensure that our grounded power supplyunitisconnected.
