CTCSS(ContinuousToneCodedSquelchSystem)provides38privacycodesandDCS(DigitallyCoded

Voice Activated Transmit (VOX)

VOXenableshands-freeoperationofyourradiobyautomaticallytransmittingwhenyouspeak.This

featureisparticularlyeectivewhenusedwithaheadsetorlapelspeaker/microphone.

VOX Sensitivity Settings

AdjustVOXsensitivity(levels1-5)tomatchyourvoicevolumeandminimizeunwantedtransmissions

frombackgroundnoise.Level1requirestheloudestvoiceinputandisthemostresistanttobackground

noise.Level5isthehighestsensitivityandactivateswithminimalvoiceinput.Foroptimalperformance,it

isrecommendedtouseacompatiblespeaker/microphoneaccessorywiththeVOXfeature.

Transmit and Receive Procedure

Yourtwo-wayradiocontainsalowpowertransmitter.Whenthetalkbuttonispusheditsendsoutradio

frequencysignals(RF).In1996theFederalCommunicationsCommission(FCC)adoptedRFexposure

guidelineswithsafetylevelsforhandheldwirelessdevices.Tocontrolyourexposureandensurecompliance

withtheoccupational/controlledenvironmentexposurelimits,alwaysadheretothefollowingprocedures:

•Transmitnomorethan50%ofthetime.

•Totransmit(talk),pressthePushtoTalk(PTT)button.

•Toreceivecalls,releasethePTTbutton.

Transmitting50%ofthetime,orless,isimportantbecausetheradiogeneratesmeasurableRFenergy

exposureonlywhentransmitting(intermsofmeasuringstandardscompliance).
