different fromcellular phone, where a duplexconnection to Your partner isestablished during the conversation.
Wecannot recommend to use automatic voice operation (VOX)inmotorbike communicationsat higher speed,
because the engine and surrounding noisecan causeunwanted triggering ofYour transmitter.Thiswillcreate
interference and can block the useofthe channelforother userswithout that You maynotice this! Depending
on the helmetmanufacturer,special Bluetooth motor bike helmets may havenoisecancelled microphones
which can allowuse of VOXcircuits evenat higher speeds.You willneed totest this!
VOXoperation maybe possiblefor other applicationsinlower noiseenvironment. In thiscaseYou willneed
an optionalavailable VOX adapter (this isa blind plug instead ofthePTT button)
Do not forget to charge both adapter and headset before each use. Even ifthe adapter isswitched off, a small
leakage currentwill discharge Li-Ionbatteriesslowly,but continuously. Thisiscommontoall deviceswith Li-
Ion batteries.
Reset and / or pairing with other devices
It mayhappen that apairing procedure wasnot successful. In that caseswitch both units offand start anew
pairing procedure. Normallyboth devicessavetheirpairinginformation inanon volatilememory,soYou do
not need to repeat the procedure before nextuse, justswitch on- that’s it.
IfYou shouldneed tousethe headset for another device,like cellularphone, You must normallyrepeat the
pairing when returning to the 2-way-radioadapter. Some headsetson the marketallowmulti-pairingfunctions.
in that case no repeated pairing isnecessary when returning o theradio.
Interface requirementsfor 2-Way-Radios
• Double audiojacks for mic(2.5 mm)und speaker /phone (3.5 mm)
• Onlyradioscan be used which have conventional grounded audio outputs. DC coupled bridge
amplifier outputs cannot work with our adapter.AllALAN and many other radioscan be used.
• For radioswith a single 2.5mm stereo audio socket, You will need our additional adapter plug
29254, because direct connection ofthe Bluetooth adapter into the Mic socket allows only
restricted VOXoperation withoutPTT.
