Operation DescriptionCongratulations on choosing the revolutionary Wireless Speaker Microphone. This incredibly compact, light-weight personal accessory extends the power of the mobile radio to the palm of your hand, whether in and out of the vehicle. It stands ready to re-dene mobile network design by increasing user functionality and mobility whilst dramatically improving the effectiveness of your infrastructure investment. This visionary solution provides users out of vehicle communications with the power and performance of their mobile radio. It cuts the cord and for the rst time puts the micro-phone and radio system access into the palm of the users hand when away from the vehicle, delivering true mobility without system compromise. Users can feel to-tally condent their private communications are kept securedue to the smart 64 bit/128 bit encryption (model dependent) functionality.The Wireless Speaker Microphone uniquely incorporates “hard wire coding” connection protocol that eliminates any possibility of outside intrusion between the unit and your vehicle’s mobile. It unleashes the power of your mobile radio allowing wireless communication with a xed mounted or vehi-cle radio: 60, 150, 300 metres or more*. Now users can communicate with enhanced clear audio, with the power and range of their mobile radio, while not being tied to the vehicle allowing the user to be truly mobile in every operational environment.Finally, if you go out of range, the blue LED will ash and the unit will sound a warning tone if you press the PTT or optional Emergency button, so you will know to move back into your communication zone or, to be simply aware. This ability to now communicate whilst outside your vehicle is a great assistance to enhancing a safer and more secure work environment for everyone who carries a Wireless Speaker Microphone. 6
60m.... 150m.... 300m... *Range is always dependent on the local terrain and communications environment. A variety of antenna congurations are available to enhance in-building penetration or, simply to extend the overall communi-cation zone around your vehicle. Ask your dealer which antenna best suits your specic application.How it worksExisting radio systemMobile base/charger connects to your mobile radio in your vehicle (or ofce) - It passes all voice trafc and alert tones to and from your Wireless Speaker MicrophoneCommunication zone7
Basic OperationPower On & OffUsually the unit will be installed such that it powers off & on in syn-chronization with the host mobile radio or by a manual switch t-ted by your installation mechanic. You can manually turn off the mobile charger by pressing the front orange button for 3 seconds and the blue LED will extinguish. You can do the same on the Wireless Speaker Microphone by pressing the lower grey button. The speaker mic will sound a de-escalating tone. To power On, do the same, releasing the button once the LED lights. The speak-er mic will sound an escalating tone. The blue LED on both units will ash momentarily and then go solid once they’re connected.Volume ControlWhen you rst activate the unit you should rst ensure your mobile radio’s volume is set to a comfortable listening level. You may then adjust the Wireless Speaker Microphone volume by pressing the right top button to increase or the left to decrease. There are 5 listening levels. The minimum level is not zero but is designed so you can still quietly hear radio trafc.Transmitting/ReceivingUse like any two way radio i.e. press the large grey PTT button to talk and release to listen. Speak with a normal voice about 3-5cm (2”) from the microphone port. Note: if you walk out of range the blue status LED will ash. If you then push the PTT an alert tone will sound to let you know your call is not getting though. Depending on your location, you may nd you need to walk back about 10 meters (yards) to re-connect. Blue status light will glow solid. The unit features a 3.5mm earpiece jack allowing use of a huge vari-ety of personalized earpieces. Plugging in an earpiece disables the internal loudspeaker for added privacy.Emergency If enabled, the emergency button can be used to trigger and reset the emergency function in your suitably equipped mobile radio. The time you hold the button is the time your mobile radio sees the emergency command. So if your mobile radio requires you to hold the radios front panel emergency button for 2 sec-onds, then you should hold the Wireless Speaker Microphone emergency button for 2 seconds.8
Multiple Unit OperationUp to three Wireless Speaker Microphones may be connected to one radio device by use of the optional Interface box accessory.Operation is identical to single user operation with the added benet that, each party also hears each other talk when they transmit. This functionality is ideal for police: where two ofcers are assigned to a patrol van, or ambulance: where up to 3 para-medics can communicate at a scene as well as with their control room. It is also ideal for ofce use allowing up to 3 personnel to access a local base or control station or remote control console while moving around a building, shop or warehouse.Note: communication between users is always routed back through their respective chargers and not direct between units. Ask your dealer for more information on this unique and valu-able capability.Motorcycle OperationThe Wireless Speaker Microphone is especially suitable for motor-cycle use. Models tted with a 6 pin Hirose industrial connector allow easy connection to a helmet microphone and dual ear-piece t out. Making use of the handlebar PTT input, a bike can be congured so that, when the rider is on the bike and presses the handle bar PTT, their headset microphone audio is sent out over the radio. Off the bike but still wearing the helmet, they can press the Wireless Speaker Microphone PTT to talk, or nally, if they remove their helmet, they can unplug the Hirose connector and use the speaker microphone like standard.Headset or Covert OperationThe 6 pin Hirose industrial connector also allows use of a variety of heavy duty and lightweight headsets and application specic audio accessories to enhance you communications capabil-ity. Use either the headset/accessory’s integral PTT or use the speaker mic PTT to transmit. The internal speaker is immediately disabled when a headset is plugged in. The small size of the unit may allow for its selective use in covert applications. The remote monitor PTT function means someone else can enable “listening” without the covert operative having to touch anything. As audio is duplex (bidirectional) you can also talk to them at the same time. A 128 bit version is also available to ensure high levels of voice security. 9
Technical Notes10Battery - ChargingThe Wireless Speaker Microphone should be charged overnight before initial use. Thereafter it may be left in the charger unit between calls, or may be worn all day and placed back at the end of the work day. The unit is designed to provide about 10-12 hours operation between charges. If the unit does start to go at a short beep will sound about once every 2 minutes. You should then re-charge the unit as soon as practicable, A fully dis-charged battery will typically recharge in less than 5 hours or less if only partially discharged. The battery will re-charge even if the mobile charger unit has been turned off. The microphone’s blue status light will indicate charging mode.Li-POLPlease recycle thoughtfullySimply place into pocket. NB: do not allow debris to ll the pocket and prevent the microphone from making contact with the charging pins.
Replacing the battery packLike all re-chargeable products, periodic replacement of the internal battery is required. The Wireless Speaker Microphone features a 1200mA Lithium Polymer battery to provide typically 10-12 hours operation when used with a busy radio channel. To maximize the life of a Lithium battery its is better to keep it topped up by returning it to the charger often rather than waiting for it to rst go at - which was the case with older nickel based batteries. Typically you can expect to get about 400-500 full re-charge cycles before the battery will require replacement.When you notice the sounding a small chirp, it in-dicates the battery is nearly at and should be re-charged. When you notice this occurring far more often than usual, it may mean it is time for the battery to be replaced. the process is simple and should only take your radio service supplier about 5 minutes to replace and test. Replacement of the battery should be ONLY undertaken by a qualied service technician so as to ensure no damage occurs to internal circuitry and to ensure the housing’s weatherproof integrity is not com-promised. The replacement battery part number is: XSMB-C12: 1200mA Lithium Polymer battery packAfter replacement, the Wireless Speaker Microphone must be rst placed back into the mobile charger and will initially need to be charged for 12 hours prior to commencement of use. Depending on the situation it may also need to be “re-connected” to the mobile charging unit)11
Re-connectionEach Wireless Speaker Microphone is uniquely con-nected to a specic mobile charger. This ensures that all communications between the two units are secure and cannot be compromised or interfered with by a third party. In the event of a Wireless Speaker Micro-phone being lost, it can be permanently disconnected from the mobile charger by connecting with a new re-placement unit.How to re-connect: hold the speaker mic while pressing both the blue up and down volume controls until the blue LED ashes and the speaker mic beeps.(About 8 secs.) Press together until LED ashes and unit beepsNow place the speaker mic back into the mobile charger. After a few seconds the speaker mic will sound a conrmation two tone and the blue LED on both units will glow solid to indicate connection is complete.Microphone adjustmentThe Wireless Speaker Microphone system is usually factory set for stand-ard audio levels required to provide satisfactory mobile radio transmit voice levels. Should the volume be too soft or loud and distorted, it may require re-adjustment to set the cor-rect level for your installation.Using a radio systems analyser to monitor the radio channel adjust the internal trim pot so as to achieve maximum permitted voice deviation within minimum voice clipping (distortion). See photo for access point Qualied service personnel only!12
Antenna choice & replacementIn the event of a damaged or lost antenna, only original replacements should be used so at to not compromise the units type approval certication.The antenna on the speaker microphone is a unity gain ground independent antenna to ensure the maximum multi-directional range. The mobile charger provides a reverse polarity sma female antenna connector. The XRMA multipolarity antenna provides enhanced coverage when mounted on an unobstructed area of a vehicle’s roof and should be connected via the sup-plied low loss coax cable. Additionally, use of approved bidirectional amplier (BDA) may also be installed using a 3 metre(10’) length of RG58A to further enhance in-building coverage from your vehicle. Only qualied ra-dio service personnel should install a BDA so as to ensure the effective radiation level remain in full compliance with regulatory requirements in your country of opera-tion.The following accessories are available from your Wireless Speak-er Microphone supplier:XSMA - replacement speaker mic antenna XRMA - Unity gain, bracket mount, multi-polarity anten-na with 5 metre (17’) low loss LMR200 coax and untted RP SMA male connector.XBDA - 12dB gain bidirectional amplier with 3 metre ( 10’) RG58A coax tail and 1 metre (39”) DC power ca-ble.13

1� Switched B+: Used to automatically turn on/off Wire-less Speaker Microphone if connected to host radio switched B+ output, if not, the user should supply man-ual on/off switch. Note: internal speaker microphone battery will still charge when the unit is turned off. 2� External Mic Audio: Audio from the Wireless Micro-phone that is to be transmitted over the host mobile radios transmitter. It is factory set for 80mV RMS.3� Radio Mic Lo: This is microphone audio ground. 4� Receive Audio: Receive audio from the host mobile radio that you wish to be sent to the Wireless Micro-phone. Ideally it should be sourced pre-volume con-trol but can be post as long as the host mobile radio’s speaker audio has been sent for comfortable listening in the vehicle.5� Power: connected via a 1 amp in-line fuse preferably direct to a vehicle’s 12V battery but can be any volt-age from about 6-15VDC. The current consumption is typically 60mA with peak current of 420mA.6� Ext� PTT: Switched ground output designed to cause the host mobile radio to transmit.7� Emergency: Output intended to connect to the host mobile radio’s emergency input. It is normally provides an active switched ground but can be jumpered to be active open circuit/high. The time held low (or high) is the exact time that the user presses their Emergency button. This output could be used for other functions such as to trigger the panic function of a car alarm system, providing it is correctly “buffered” so as to not cause damage to the mobile charger.8� COR/squelch/audio unmute: Input designed to moni-tor the receive status of the host mobile radio. Ideally, it is driven by an “audio unmute” command in the host mobile. i.e. when the radio’s speaker unmutes to pass audio then the COR input should toggle in sync. Installation & Connections15
Alternatively, it could be driven by the radio’s unsquelch command that factors in reception of required correct CTCSS tones, etc. Internal jumpering caters for active low or high inputs.9� Ground: DC ground connection. 13� Remote PTT: This provides a remote alternative to transmit Wireless Speaker Microphone audio via the host mobile radio. You may choose to connect to a motorbike handle bar PTT, a hidden palm or footswitch, a wireless PTT device, or even to an output from the host mobile equipped to provide remote radio monitoring of the Wireless Speaker Microphones users audio. In such remote monitoring cases, use of the remote PTT input causes the sensitivity of the Wireless Speaker Micro-phone to be greatly increased, so a control room oper-ator can more easily monitor the health or safety of the user. There is no increased audio gain when a headset is connected to the base of the Wireless Microphone.15� Ground: Additional DC ground connection.Alternate CongurationsSome alternate congurations are available by in-ternal jumpering of the mobile charger unit. These are provided to typically allow compatibility with different mobile radio types. Re-conguration of these jumpers should only be undertaken by qualied radio service personnel.To access, rst remove the rear mounting plate. Next remove the 4 screws to access internal PCB. Take ex-treme care when handling the PCB to prevent damage by electrostatic discharge (ESD) or to internal wiring. Re-assemble carefully remembering to re-insert the belt clip securing spring.16
