Connections
When removing green connectors for feeding cables through holes,
ensure all are refitted at the correct polarity before connection to the
amplifier.
It is recommended to take photos as a record before taking any cables
apart. This is to ensure proper reconnection; incorrect wiring may impact
performance.

there is power
at the socket).

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
interference
through
speakers
(buzzing /
whistling /
hissing).
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
