Motorbike communication system
AE500
Purpose for use
The communication system AE 500has beendesigned for speech communicationbetweenmotorbikedriver
and passenger. Toachievethis you use thesupplied helmet speaker sets whichhave tobe fittedinto already
existingintegralhelmets (the set cannot beinstalled in jet helmets). The set gives youthe opportunityfor duplex
communicationbetween driver and passenger and vice versa.
The integratedMono FMradio can be switchedoverto radio reception.The talking connection has priorityto
radio reception: while talking theradio volume will beautomaticallydecreased.
Furthermore the following equipment can be connected:
• external MP 3 or CD/DVD player via 3.5 mmjackplug(instead ofintegrated radio)
• aradiowithPMR446 or LPD standardfor driver andpassenger in connectionwith supplied
transmit (push-to-talk)keys
• GSM mobilephone(automatic incoming call switchingmode must be active) for driver.
The set is being operatedwith2xAA sizeAlkalineor rechargeableNiCd/ NiMH batteries independent from
vehiclepower supply.

Declaration of Conformity:
The motorbikecommunication systemfulfills the European EMC standards. such as EN 55 013 (radio), EN 301
489-1,EN301489-5 (EMCfor professional radios and accessories) andEN60950(electric safety)andit
carries the CE-mark.
Conditions for accessories
Radio connection: The radio connection ofthe AE 500 fits to most of PMR with 2.5 mm/3.5 mm plug
combination.T
many other radios. It is not recommendable to use the VOX-function because of the high level of sound
he universal plug 2.5 mm for microphone and and 3.5 mm for the ear set is being supported by
(basicallyyoucanonlyuse the VOX-function as long as no additional mobile phone is connected, since
using thetalkbutton is theonlycriteria to differentiate between radio and mobile phone).
MP3/DVD/CD-connection: 3.5 mmstereo plug. The radio is beingswitchedoff the moment the cable is being
inserted.
GSMmobile phone): universal hands-free connectionvia2.5mmstereo plug (likei.e.at Motorola phones).
For most telephone brandsyou canfind suitable adapters in anyGSM phoneaccessoryshop, becausethe
2.5mmstereo plug is the quasi-standard for various hands-free kits.
The telephone has to be able to beprogrammed to „automatic call reception” andadjusted likewise.
Hints for installation and connection
Fitting of helmet set:
The twohelmet sets consist oftwoultraflat padded ear sets to be inserted in thehelmet, amicrophone to be
installedinside thehelmet close to your mouth and awaterprooftransmit talkbutton whichcanbefixed within
reach ofthe handle-bar or at your glove.
Supplied are two self-adhesive pads for fitting the set in thehelmet and avelcro tapeadjustable in lengthto
install the talkbutton. Theseadhesive pads do have an adhesive surface on oneside (remove protective foil),
on the other sidethereis avelcroclaspso thatear set andmicrophonecanbeeasilyinstalledor removed.
Bikers withonlylimited space to install thetalkbutton i. e. on ametal plate atthehandle bars mayremove the
velcro tape and stickthe talkbutton with adhesive pads directlytothedesired location.
Please fix theearsets with still asmall gapbetween theears andthehelmet. Your ears should notbe
completelycoveredbythe ear set because thenyou might notbe able to listento thesurroundingnoiseof
traffic (due to RoadTraffic Act youmaynotuse headsets that completelycover your ears because youmight
overhear honking or other signals).
Please donot carryout any changesat thehelmet before installing the headset. ECE normfor motorbike
helmets does not permit to flattenthematerialinsidethehelmet i. e. tomakespace for theear set. Fix the
microphone inside thehelmet close to your mouth withthe supplied velcro tape. Before fixing the adhesive pads
thoroughlyclean thedesiredlocation (i.e. with alcohol,but do notuse anysolvent). Press tightlyand remember
that it takes several hours until the final strength has been achieved.
You onlyneed the talkbuttons in case youwant tooperate an additionalPMR(radio). You donot need the talk
buttons for the basic intercomfunction between driverand passenger or radio/MP3.
Storing of the central unit
The best place for storingis inside or close to the tank knap sack.The velcro tapeat thecentralunit makes this
veryeasy.The cables leadingto the driver simultaneouslyserve as the radio antenna. Storing the centralunit
in thedriver`s pocket can onlybeasubstitutebecause cables close to the bodyonlyhave alimited antenna
function.
Installing the radio and/or mobile phone
Radio andmobilephonedoonlyachievetheir maximumradiationifinstalleddetachedfromsurroundings. If
being used atthe sametimeboth should be as farapart as possiblefrom eachother and from the central
unit. Temporarystoragein your pockets does reduce range. Never place radio, mobile phone and /or central
unit in the samepocket, undesired interferences, especiallyfromGSM whiletransmission mayoccur.
If you do not use a radio or mobile phoneplease cover the unusedplug with tape. Do not cut off unused cables!

The connections to the helmet set (black) and thetalk buttons(yellow)are waterproofand cannotbe mixedup.
Connect theplugs with the markings facing eachother.
Apart fromapossiblyconnected mobile phonetheconnections ofdriver and passenger have thesamepriority.
Mobile phone calls can onlybeaccepted at the driver`s head set as astandard. In case the passenger is
supposedtousethephone insteadofthedriver pleaseexchangetherelevantconnections before startingyour
trip!
Power supply/ Inserting of batteries
Open thebatterylid at the bottom ofthe central unit.Insert twobatteries or rechargeable batteries size AA
(Mignon). Payattentiontothe correct positionofthe batterypoles.Power consumption duringoperationis very
low:40to50hours operating timewithalkalinebatteries, about30hours withrechargeablebatteries. Please
use an external charger to charge possiblyused rechargeable batteries.
Warning: Never use batteries and rechargeable batteries mixed in the batterycompartment. Onlyuse
batteries or rechargeable batteries of the samekind, and never mix full and emptybatteries. Dispose
ofused batteries onlyat the authorized collecting points atspecialdealers. Payattentionto the
different containers for batteries andrechargeablebatteries. Batteries and rechargeable batteries are
special waste, theymaynot bedisposed ofwith household garbage.Neverthrowbatteries or
rechargeable batteries intoanyfire, never short-circuit the poles ofbatteries or rechargeable
batteries: Danger of fire, explosion or injury may occur!
Operation
Radio and intercomcan be switchedonand operatedseparately.Please makesure that radio and intercom are
both switched off ifnot used. The red LED light is onifunit is readyfor operation.
Radio: Switching on/off is done with thevolume setting integrated in the rotarypotentiometer (1).
The radiohas automatic frequencysearch function. Start automatic station search bypressing SCAN/UP key
(2).The automatic frequencysearch will nowscan the FM radio range beginning at thelower limit close to 87.4
MHzto theupper end at 108 MHzfor receiving signals and will stop at anysignal which is strong enough for
reception. Once having stoppedat astation, youmayrestart again from this position bypressing the
SCAN/UP consequently.The frequencysearch will stop whenit has once reached the upper frequencyrange
limit.
Toreset the radio for anewfull frequencysearch, use the lower key RESET/DOWN. This willreset the
frequencyto the lower limit 87.4MHz. Press nowthe SCAN/UP buttontostart frequencyserach againin
upwards direction.

Intercom:
The intercomcommunication qualitybetween driver and pillion depends on theenvironmental noise and the
correct sensitivityadjustment. AE 500 has a 4 position slideswitch (3).
Ifyoudo not need theintercom(in case that youonlywantto listen tobroadcast radio) use theleftposition,
Intercom (OFF).
The intercomenables a full duplex conversation: fromdriver's mic to pillion's headphones and vice versa.
You mayselect 3 different settings:
Position L(Low): For high speed motorbikedriving. The mic sensitivityis ratherlowto avoid excessive noise
pick-up. The setting is adjusted to normal biker's talking behaviour: You speakautomaticallylouder ifyou arein
a noisy,high speed envirionment.
Position M(Medium): Formediumspeed. The mic is nowmore sensitive,butmayreact towind andengine
noise in higher speed situations.
Position H(High): Highsensitivity,for lowspeedand other applications. The mic reacts to normal voice
volume.
Automaticradio muting: Aspeech detectioncircuit will reduce (mute) the radioor MP3player volume
automatically,as soon as you start speaking to your partner and ifthe voice will be loud enough. Dependingon
the switch position(L, MorH) themuting starts at different speech loudness points,which ensures that the
radiomuting doesnotreacttowindandenginenoise.It is agoodideatomakeavoice trainingtospeakas
loud as the mute switch requests: thiswill be the optimumsound level pointfor the intercom.
A short moment after you stop talking, the radio or MP3 volumewill automaticallyreach theformer value again.
2-wayradio conversation:
Anyvoice communication can also be transmitted via 2-way radios likePMR 446, LPD, CB or other suitable
commercial radios. PMR 446 canprovide a communication range to up to 5kmunder optimumconditions (radio
mounted on the motor bike for free-space radiation). All you need is to plug in the 2.5mm plug into the
microphone and the 3.5 mm plug into the speaker/phone sockets ofyour radio and to conect thepush-to-talk
keyssuppliedwiththe AE 500system.Please use the sameswitch position(L, Mor H)as for intercom.
Becausesomecommercial radio models can provideaveryhigh loudness volume, youshouldinitiallycheck
with lower receiving volume and increaseonlyifnecessary.
Please use thepush-to-talk(PTT) switch ifyouliketospeakover the radio channel(without PTTswitch only
intercomis possible!). The MIC loudness to theradio is automaticallyadapted byselection ofH, L, or Mswitch
position,same as for intercomuse. Release the push-to-talkkeyafter you have finished speaking.
2-wayradio receiving: Radio receiving has priorityagainst broadcast or MP3player audio. Incoming radio
communications fromother stations will automaticallymute the FM broadcast radio andMP 3player. Mutingis
controlled bythe squelch setting ofthe 2-wayradio. After the radio channelbecomesquiet again, the volumeof
the broadcast or MP 3 player audio will be increasedagain.
GSMphone at driver's headset:
Insert the2.5 mmstereo plug intothehandsfree socket ofyour mobile phone.Ifthe plug should notfit, usean
adapter, offered in all mobile phone accessoryshops(the 2.5 mmstereo plug systemis aquasi-standardfor
handsfree kits). Please programyour mobile phone to automatical incoming call switching!
You will hear anincoming phonecall in theheadphones. Phone calls have priorityagainst broadcast radio and
MP 3and will mute thesedevices. AE 500 has beendesigned toanswer incoming calls onlyfromdriver's
headset. Pleasedo not use the push-to-talk keyPTT (if installed) during mobile phone conversations,
because this would automaticallyswitch your voice to the 2 wayradio instead ofthe mobile phone!
