Microphone & Speaker Installation
1. Placethestamicrophoneonthestasideof
the partition, ensuring that it does not cause an
obstructionandisasclosetostaaspossible.
It is ideally positioned no more than 300mm
awayfromthestamember.
2. Usethecablemanagementholetorunthesta
microphonecablebacktotheamplier.Ifthere
Sta
microphone
is not already a cable management hole, drill in a suitable location near
therearofthecounter.
3. Findasuitablelocationforsurfacemountedentryunit.Itisideallybe
placedatheadheight(approximately1.65m)fromthegroundtoallow
mostcustomerstoeasilypressandspeakintoit.
4. Markthefourxingpointsforthesurfacemountedentryunitanddrill
theholes.
5. Secure the surface mounted entry unit to the surface using the screws
provided.
6. Runthecablesfromthepodsthroughthroughthesurface.
7. Routeallthecablingneatlytotheamplierlocationonthestaside.

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.
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eldwillbedirectedtowardsuser’sheadheights.

2. Adjuststavolume(VolumeIn)toacomfortablelevel.
3. Increasecustomervolume(VolumeOut)untilfeedbackisheard.
4. Decreasecustomervolume(VolumeOut)untilfeedbackisjusteliminated.
Checkthattheamplierisfullyfunctionalbyensuringthered‘fault’light
isNOTdisplaying.
5. Ifthereisinsuicientvolumeevenafteryouhaveadjustedthevolume
controls,enterengineersmodeandraisemaxvolumesettings.Exit
engineersmodeandrepeatinitialsetup.
6. Thesystemisnowreadytouse.
