0 INTRODUCTION

0.1 General

Based on the GSM/GPRS and state-of-art GPS technology for satellite
navigation, FALCOM introduces a new powerful pocket size device with a stand­alone software system for personal safety and security as well as asset monitoring.
FALCOM MAMBO consists of the GSM/GPRS engine, 20-channel GPS receiver,
Bluetooth™ class 2.0 and a 3-D motion detector (in the state of inactivity it can be
set into the low power mode) as an all-in-one solution.

FALCOM MAMBO is a Tri-band GSM/GPRS engine that works on the three
frequencies either GSM 900/1800/1900 MHz or GSM 850/1800/1900 MHz. The
integrated GPS receiver architecture based on the SiRFstarIII chipset, provides more
than enough precise location information using satellite signals to enable it to track
people wherever they are in the world. With its integral housing, compact design,
ultra-low power consumption, easy-to-carry and easy-to-use, it is an outstanding
quality, high-performance, operating as a stand-alone device ideally suited for
personal security, asset management and automotive applications as well. The
configurable internal firmware is a fundamental component, which in combination
with the excellent hardware performance makes the FALCOM MAMBO device to be
the best application where the fleet management and personal security today are
required. Operating as a stand-alone personal security device, manufactured in a
form factor 85 mm x 59 mm x 25 mm and weighing less than 120 grams with battery,
it can be easily fit in a jacket pocket (e.g. into a child's pocket). Ease-of-use is
ensured with just three touch-buttons and three LEDs. Each LED includes three­different lighting colors. Each Button and LED is free-configurable. Based on the
internal firmware all Buttons and LEDs can be adjusted to the user requirements.
Depending on the user-defined configuration, each touch-button can execute
more than one action (voice call, TCP packets, SMS generation etc.). In the event of
emergency, the person carrying the device can contact a range of services by
pressing just a button. Upon button activation, the equipment uses the GPS signals to
define its accurate position, and it sends a SMS message with its location information
or it performs a voice call to one of the predefined numbers via the GSM network.
With the help of the implemented TCP/IP protocol, FALCOM MAMBO (person who
carrying it) can be continually tracked and monitored live from any Internet
connection point around the world.

FALCOM MAMBO provides Geofence features, which can be used for territory
management, route verification, prohibited locations, and more. Once a Geofence
area is manually set-up, the device automatically notifies the destination number via
SMS, Voice or Data calls or TCP, if the person carrying it enters into and/or leaves the
pre-defined area(s).

The FALCOM MAMBO contains a History function which enables it to archive unique
locations in sequence for up to 45 days long (for example, archive interval up to 20
sec.) and at a later time the history data can be downloaded either locally via
Bluetooth or over-air GSM network or TCP-connection for further evaluation.

Additionally, the FALCOM MAMBO is also a high-capacity navigation system, an
intelligent and dynamic destination guidance that allows you to navigate freely
without the hassle of messy wire connections. The integrated Class 2 Bluetooth™
transceiver in the FALCOM MAMBO is capable to communicate with any Serial Port
Profile Bluetooth™ device and to transmit its data within a 10m radius. The FALCOM
MAMBO in communication with your installed GPS Mapping software on the
Bluetooth™-enabled device points you the way comfortably and reliably from the
current location A to your desired destination B.

1 SECURITY

IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM, READ
THIS INFORMATION BEFORE USE!

Your cellular engine MAMBO is one of the most exciting and innovative electronic
products ever developed. With it, you can stay in contact with your office, your
home, emergency services and others, wherever service is provided.

This chapter contains important information for the safe and reliable use of the
MAMBO device. Please read this chapter carefully before starting to use the cellular
engine MAMBO.

1.1 General information

Your MAMBO device utilizes the GSM/GPS standard for cellular technology. GSM is a
newer radio frequency („RF“) technology than the current FM technology that has
been used for radio communications for decades. The GSM standard has been
established for use in the European community and elsewhere. Your MAMBO is
actually a low power radio transmitter and receiver. It sends out and receives radio
frequency energy. When you use your modem, the cellular system handling your
calls controls both the radio frequency and the power level of your cellular modem.

1.2 Exposure to RF energy

There has been some public concern about possible health effects of using a GSM
modem. Although research on health effects from RF energy has focused for many
years on the current RF technology, scientists have begun research regarding newer
radio technologies, such as GSM. After existing research had been reviewed, and
after compliance to all applicable safety standards had been tested, it has been
concluded that the product is fit for use.

If you are concerned about exposure to RF energy there are things you can do to
minimize exposure. Obviously, limiting the duration of your calls will reduce your
exposure to RF energy. In addition, you can reduce RF exposure by operating your
cellular modem efficiently by following the guidelines below.

1.3 Efficient modem operation

In order to operate your modem at the lowest power level, consistent with
satisfactory call quality please take note of the following hints.

 If your device has an extendible antenna, extend it fully. Some models

allow you to place a call with the antenna retracted. However, your
modem operates more efficiently with the antenna fully extended.

 If your device has an external antenna, do not hold the antenna when

the modem is „IN USE“. Holding the antenna affects call quality and may
cause the modem to operate at a higher power level than needed.

1.4 Driving

Check the laws and regulations on the use of cellular devices in the area where you
drive. Always obey them. Also, when using your modem while driving, please pay full
attention to driving, pull off the road and park before making or answering a call if
driving conditions so require. When applications are prepared for mobile use they
should fulfil road-safety instructions of the current law!

Mambo Hardware Description Version 1.01

1.5 Electronic devices

Most electronic equipment, for example in hospitals and motor vehicles is shielded
from RF energy. However, RF energy may affect some malfunctioning or improperly
shielded electronic equipment.

1.6 Vehicle electronic equipment

Check your vehicle manufacturer’s representative to determine if any on board
electronic equipment is adequately shielded from RF energy.

1.7 Medical electronic equipment

Consult the manufacturer of any personal medical devices (such as pacemakers,
hearing aids, etc.) to determine if they are adequately shielded from external RF
energy.

Turn your MAMBO device OFF in health care facilities when any regulations posted in
the area instruct you to do so. Hospitals or health care facilities may be using RF
monitoring equipment.

1.8 Aircraft

Turn your MAMBO OFF before boarding any aircraft.

Use it on the ground only with crew permission.

Do not use it in the air.

To prevent possible interference with aircraft systems, Federal Aviation Administration
(FAA) regulations require you to have permission from a crew member to use your
modem while the plane is on the ground. To prevent interference with cellular
systems, local RF regulations prohibit using your modem whilst airborne.

1.9 Children

Do not allow children to play with your MAMBO device. It is not a toy. Children could
hurt themselves or others (by poking themselves or others in the eye with the
antenna, for example). Children could damage the modem or make calls that
increase your modem bills.

1.10 Blasting areas

To avoid interfering with blasting operations, turn your device OFF when in a
“blasting area” or in areas posted: „turn off two-way radio“. Construction crew often
uses remote control RF devices to set off explosives.

1.11 Potentially explosive atmospheres

Turn your MAMBO device OFF when in any area with a potentially explosive
atmosphere. It is rare, but your modems or their accessories could generate sparks.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or even
death.

Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fuelling areas such as petrol stations; below decks on boats;
fuel or chemical transfer or storage facilities; and areas where the air contains
chemicals or particles, such as grain, dust or metal powders.

Mambo Hardware Description Version 1.01

Do not transport or store flammable gas, liquid or explosives, in the compartment of
your vehicle, which contains your modem or accessories.

Before using your modem in a vehicle powered by liquefied petroleum gas (such as
propane or butane) ensure that the vehicle complies with the relevant fire and
safety regulations of the country in which the vehicle is to be used.

1.12 Non-ionizing radiation

As with other mobile radio transmitting equipment users are advised that for
satisfactory operation and for the safety of personnel, it is recommended that no
part of the human body is allowed to come too close to the unit during its operation.

1.13 Battery safety

The safety rules below are applied for the internal battery. Mistreating the battery
may cause the battery to get hot, crack, or inflame and cause serious injury. In order
to avoid any damage and extend the life expectancy of battery, please follow the
safety rules listed below before using the MAMBO device:

• Do not place the battery on, in or near fires, apparatus that provide heat,
or other high-temperature locations. Do not place the battery in direct
sunshine, or use or store the battery inside cars in hot weather. Doing so
may cause the battery to generate heat, crack, or inflame. Using the

4 MAMBO INTERFACES

4.1.1 Buttons & LEDs

The MAMBO device operates with the push of buttons. The MAMBO device can be
turned on by pressing the B1 for longer than 5 seconds. After 4-5 seconds a beep
tone is generated and the status indicators L1 and L3 light for a short time, notifying
the unit is powered on. All other buttons are not configured, they are kept free for
user requirements. Thus you have the possibility to configure all 3 available Buttons

depending on what configuration is most important for you. Depending on your
specific requirements all 3 integrated LED indicators can also be programmed.
References to customize the configuration of your MAMBO device are available in
the MAMBO software manual

“MAMBO_firmware_2.3.17_user_manual.pdf”.

4.1.3 Audio interfaces

The MAMBO device supports two audio channels, depending on the user­configuration, the incoming/outgoing voice calls (voice conversations) can be
forwarded either to the internal speaker/microphone or to the external audio
interface (4-pin audio connector for headset).

4.1.3.1 External audio interface

This interface allows you to connect a headset to the MAMBO. See related
documents [2], page 5, for included Headset description.

Figure 3: Audio interface for headset

4.1.3.2 Internal speaker and microphone

The internal speaker and microphone allows you to make voice conversation with
another call party without using of any headset. The ringer volume and ringer
melody on this interface can be adjusted by the internal operating firmware.

4.2 Automatic GPRS Multislot Class change

Temperature control is also effective for operation in GPRS Multislot class 10. If the
board temperature exceeds the specified limit while data are transmitted over
GPRS, the module automatically reverts from GPRS Multislot class 10 (3 RX x 2 TX) to

class 8 (4 RX x 1 TX). This reduces the power consumption and, consequently, causes
the temperature of board to decrease. Once the temperature drops to a value of 5
degrees below the limit of restricted operation, MAMBO returns to the higher Multislot
class 10. If the temperature stays at the critical level or even continues to rise,
MAMBO will not switch back to the higher class. After a transition from Multislot class
10 to Multislot class 8 a possible switchback to Multislot class 10 is blocked for one
minute. Please, note that there is no one single cause of switching over to a lower
GPRS Multislot class. Rather it is the result of an interaction of several factors, such as
the board temperature that depends largely on the ambient temperature, the
operating mode and the transmit power. Furthermore, take into account that there
is a delay until the network proceeds to a lower or, accordingly, higher Multislot
class. The delay time is network dependent. In extreme cases, if it takes too much
time for the network and the temperature cannot drop due to this delay, the
terminal may even switch off.

4.2.1 Automatic shutdown

Automatic shutdown takes effect if:

• the MAMBO board is exceeding the critical limits of over or under
temperature.

• the battery is exceeding the critical limits of over or under temperature.

• Battery under voltage is detected.

The automatic shutdown procedure is equivalent to the power-down initiated, i.e.
MAMBO logs off from the network and the software enters a secure state avoiding
loss of data.

5 APPENDIX

5.1 What should be considered when using the MAMBO

device

The MAMBO is a device, which is based on the applications supported by the
operating firmware. The applications are based on events and states handling.
Events can be generated at run-time or by a user action, such as receiving a voice
call, pressing a button etc. In order to start applications with MAMBO and to obtain
maximum benefit from operating software, please, refer to the separated manual
“mambo_firmware_2.3.17_user_manual.pdf”. This document provides a large amount
of information to create a wide range of GSM/GPS/GPRS (internet) applications.
