Tait TP9500 - Changing to Silent Operation; Turning On Active Noise Cancellation

Changing to Silent Operation
Whensilentoperationison,alltheradio’saudibletonesareturnedoff,andonlychanneltrafficcanbeheard.
To turn silent operation on or off:
1.PressMenuandselect Radio settings > Alert settings > Silent operation.
2.IntheSilent operationmenu,scrolltoeitherOnorOffandpressSelect.
Dependingonhowyourradioisprogrammed,youmaybeabletopressafunctionkeytotogglesilent
operationonandoff.
Whilesilentoperationison,the iconappearsinthedisplay.
Turning On Active Noise Cancellation
Activenoisecancellationusesasecondarymicrophoneonthebackoftheradiotoactivelyfilteroutnoiseinloud
environments,makingiteasierforrecipientstodiscernthespeechofthetalkingpartywhoisinanoisyenvironment.
Activenoisecancellationcanbeleftonregardlessofenvironment.However,whensafetyfeaturessuchasLone-
workerMonitoringorRadioMonitorareactivated,thelistenermayloseawarenessofthenoisyenvironment.Tait
recommendsusersimplementsupplementaryprocedurestoaccountforthis.
Thecomplementaryfeatureofmicrophonesensitivityallowstheinternalandexternalmicrophonestobeconfiguredto
suitthetypeofenvironmenttheuserisin,furtherimprovingaudioquality.Whenactivenoisecancellationisenabled,
sensitivityshouldbedecreased.Inaquietenvironment,increasingthesensitivityissuggested.
Forbestresults,Taitrecommendsholdingtheradio2.5-5cm(1-2inches)fromthemouthandspeakingdirectlyinto
theradiospeaker/mic.
To turn active noise cancellation on or off:
1.PressMenuandselect Radio settings > Functions > Noise cancellation.
