2) Ensure induction loop connector is

wiredcorrectlyandrmlypluggedin.

I can’t hear

audio through

the induction

loop.

1) Induction loop or microphone is

disconnected.

2)Looptesterhasafault.

1 ) Check instructions for correct

connections and, if possible, check

the hearing device with a known

workinghearingloop.

2) Ensure loop tester has a new set

ofbatteries.

I can hear

incloseproximity.

2)Internalvolumegainsettohigh.

3) Incorrect power supply being

used.

1)Switchoanythirdparty
