VOXadjustment

TheU9911‐BSChasaninnovativevoiceactivation(VOX)system.VOXisintendedtoprevent

backgroundnoisefrombeingunintentionallypickedupbythemicrophonewhiledetectingand

allowingvoicecommunications.TheVOXknob(seeFigure1)controlsthethresholdatwhichthe

micbecomes“hot”.Whenthemicishotyouwillhearyourownvoiceandotherconnectedusers

willhearyouaswell.PressingthePTTbuttonwillautomaticallymakethemicrophone“hot”for

aslongasthePTTishelddown,regardlessofVOXsetting.

VOXBasics

• VOXknobfullyclockwise(CW):  Micisoff

• VOXknobfullycounter‐clockwise(CCW):Micis"hot"

• VOXknobin‐betweenfullCWandfullCCW:VOXenabled



VOXAdjustmentProcedure



1. Ensurethatthecontrollerislinkedwithabeltstation(LEDflashinggreen).

2. Standinthenoisyenvironmentwhereyouwillbeusingthesystembutdonotspeak.

3. TurnVOXknobfullycounter‐clockwise.Youwillhearacontinuoustone.

4. Whilecontinuingnottospeak,slowlyturntheVOXknobclockwiseuntilthetonestops.

5. VOXisnowoptimallysetforyourenvironment.



Ifyoumovetoanotherlocation,youmaywishtorepeattheaboveprocedure.



19541P‐44(02‐11)

Tip:

• TurningtheVOXknobfullyclockwisewillturnoffthemicrophone.

• Conversely,turningtheVOXknobfullycounter‐clockwisewillcausethemicrophoneto

be“hot”allthetime.



Communication

Theuserwillhearhisownvoice(side‐tone)onlywhenthecontrollerisconnectedtoabelt

stationandVOXisproperlyadjusted.Side‐toneprovidesfeedbackfortheusertoknowheis

connectedandisbeingheardbytheremoteusersaswell.Ingeneral,ifyoucanhearyourown

voice,theotheruserscanhearyouaswell.

Range

Therangeofabeltstationandacontrollercanbeupto300ft(100m).Ifyouareinan

environmentwithmetalorconcretewalls,thisrangecouldbereduced.Whenthebeltstation

travelsoutofrangeofthecontroller,avoicealertwillindicatethattheconnectionhasbeenlost.

Toreconnect,simplymovebackintorangeandconnectionwiththecontroller/gatewaywill

automaticallybereestablished,alsonotedbyavoicealert.



LowBattery

Undertypicalconditions,thebatteryinthecontrollerwilllastupto24hoursorlonger.Avoice
