Operation Description
Congratulations 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-dene 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 condent 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.

60m.... 150m.... 300m...
*Range is always dependent on the local terrain and
communications environment. A variety of antenna
congurations 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 specic application.

Basic Operation
Power On & Off
Usually 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 Control
When 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 trafc.
Transmitting/Receiving
Use 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.

Multiple Unit Operation
Up 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
benet that, each party also hears each other talk when they
transmit. This functionality is ideal for police: where two ofcers
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 ofce 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 Operation
The 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 congured 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 Operation
The 6 pin Hirose industrial connector also allows use of a variety
of heavy duty and lightweight headsets and application specic
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.

Battery - Charging
The 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-POL
Please recycle thoughtfully
Simply 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 pack
Like 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 qualied 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 pack
After 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-connection
Each Wireless Speaker Microphone is uniquely con-
nected to a specic 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 beeps
Now place the speaker mic back
into the mobile charger. After a few
seconds the speaker mic will sound
a conrmation two tone and the
blue LED on both units will glow solid
to indicate connection is complete.
Microphone adjustment
The 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
Qualied service personnel only!

Antenna choice & replacement
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 to the output of the mobile
charger. Alternatively use of an approved bidirectional
amplier (BDA) may also be installed to further enhance
in-building coverage from your vehicle. The XBDA is in-
stalled in series by using a 3 metre (10’) length of RG58A
connected to the output of the mobile charger. The
XRMA antenna then connects to the output of the
XBDA. Only qualied radio service personnel should in-
stall a BDA so as to ensure the effective radiation level
remain in full compliance with regulatory requirements
in your country of operation�
In the event of a damaged or lost antenna, only original
replacements should be used so at to not compromise
the units type approval certication.
The antenna on the speaker microphone is a unity gain
ground independent antenna to ensure the maximum
multi-directional range. The mobile charger output pro-
vides a reverse polarity sma female antenna connec-
tor as does the XBDA.
The following accessories are available from your Wireless
Speaker Microphone supplier:
XSMA - replacement speaker mic antenna
XRMA - Unity gain, bracket mount, multi-polarity an-
tenna with 5 metre (17’) low loss LMR200 coax and
untted RP SMA male connector.
XBDA - 12dB gain bidirectional amplier with 3 metre
(10’) RG58A coax tail and 1 metre (39”) DC power
cable.

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 & Connections
15
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 Congurations
Some alternate congurations are available by in-
ternal jumpering of the mobile charger unit. These
are provided to typically allow compatibility with
different mobile radio types.
Re-conguration of these jumpers should only be
undertaken by qualied 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.

Vehicles Equipped with Air Bags:
An air bag inates with great force. Do not store the Wireless Speaker Micro-
phone or any of its accessories in the area over the air bag or in the air bag
deployment area.
Carrying and handling:
The unit contains sensitive components. Do not drop, disassemble, micro-
wave, burn, paint, or insert foreign objects. Do not use the unit if it has been
damaged—for example, if it is cracked, punctured, or damaged by water.
Keeping Clean:
Clean the Wireless Speaker Microphone and mobile charger immediately
should they come into contact with any contaminants that may cause mal-
function—e.g, ink, oils, dirt, food and drinks. To clean, turn off (press and hold
the On/Off button) and remove all cables. Then use a slightly damp soft cloth.
Don’t use solvents, turpentine window cleaners, or abrasive household clean-
ers to clean the unit.
Connectors and Press buttons:
Never force a connector into a port or apply excessive pressure to a button,
because this may cause damage that is not covered under the warranty. If
the connector and port don’t join with reasonable ease, they probably don’t
match. Check for obstructions and make sure that the connector matches
the port and that you have positioned the connector correctly in relation to
the port.
