1 Security
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM MODEM READ THIS INFORMATION BEFORE USE !
Your GSM modem 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.
1.1.1 GENERAL
Your modem utilises the GSM 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 modem 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.
1.1.2 EXPOSURE TO RF ENERGY
There has been some public concern about possible health effects of
using 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 minimise 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 below guidelines.
1.1.3 EFFICIENT MODEM OPERATION
For your modem to operate at the lowest power level, consistent with
satisfactory call quality:
If your modem 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.
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.
1.1.4 ANTENNA CARE AND REPLACEMENT
Do not use the modem with a damaged antenna. If a damaged antenna
comes into contact with the skin, a minor burn may result. Replace a

Page 8
SAMBA 55/56 VERSION 1.07
damaged antenna immediately. Consult your manual to see if you may
change the antenna yourself. If so, use only a manufacturer-approved
antenna. Otherwise, have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorised antennas,
modifications or attachments could damage the modem and may
contravene local RF emission regulations or invalidate type approval.
1.1.5 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: give 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 roadsafety instructions of the current law!
1.1.6 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.
1.1.7 VEHICLE ELECTRONIC EQUIPMENT
Check your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
1.1.8 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 modem 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.
1.1.9 AIRCRAFT
Turn your modem OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use 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.
1.1.10 CHILDREN
Do not allow children to play with your modem. It is not a toy. Children
could hurt themselves or others (by poking themselves or others in the
This confidential document is the property of FALCOM GmbH and may not be copied or circulated without permission.
Page 9
SAMBA 55/56 VERSION 1.07
eye with the antenna, for example). Children could damage the modem,
or make calls that increase your modem bills.
1.1.11 BLASTING AREAS
To avoid interfering with blasting operations, turn your unit OFF when in
a « blasting area » or in areas posted : « turn off two-way radio ».
Construction crew often use remote control RF devices to set off
explosives.
1.1.12 POTENTIALLY EXPLOSIVE ATMOSPHERES
Turn your modem OFF when in any area with a potentially explosive
atmosphere. It is rare, but your modem or its 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.
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.
1.1.13 NON-IONISING 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 be allowed to come too
close to the antenna during operation of the equipment.
The radio equipment shall be connected to the antenna via a non-radiating
50Ohm coaxial cable.
The antenna shall be mounted in such a position that no part of the human
body will normally rest close to any part of the antenna. It is also
recommended to use the equipment not close to medical devices as for
example hearing aids and pacemakers.

4.1 Description of operating modes
The chapter below briefly summarizes the various operating modes referred to
in the following chapters.
Definition of the GPRS class B mode of operation:
The definition of GPRS class B mode is, that the MS can be attached to both
GPRS and other GSM services, but the MS can only operate one set of
services at a time. Class B enables making or receiving a voice call, or
sending/receiving an SMS during a GPRS connection. During voice calls or
SMS, GPRS services are suspended and then resumed automatically after the
call or SMS session has ended.
4.1.1 Normal mode operation
4.1.1.1 GSM/GPRS SLEEP
Various power save modes set with AT+CFUN command, see related
documents [3]. Software is active to minimum extent. If the module was
registered to the GSM network in IDLE mode, it is registered and paging with
the BTS in SLEEP mode, too. Power saving can be chosen at different levels:
The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface.
The CYCLIC SLEEP modes AT+CFUN=5,6,7,8 and 9 alternatively activate
and deactivate the AT interfaces to allow permanent access to all AT
commands.
4.1.1.2 GSM IDLE
Software is active. Once registered to the GSM network, paging with BTS is
carried out. The module is ready to send and receive.
4.1.1.3 GSM TALK
Connection between two subscribers is in progress. Power consumption
depends on network coverage individual settings, such as DTX off/on,
FR/EFR/HR, hopping sequences, antenna.
4.1.1.4 GPRS IDLE
Module is ready for GPRS data transfer, but no data is currently sent or
received. Power consumption depends on network settings and GPRS
configuration (e.g. multislot settings).

Page 21
SAMBA 55/56 VERSION 1.07
4.1.1.5 GPRS DATA
GPRS data transfer in progress. Power consumption depends on network
settings (e.g. power control level), uplink/downlink data rates and GPRS
configuration (e.g. used multislot settings).
4.1.2 Power down
Normal shutdown after sending the AT^SMSO command. The Power Supply
ASIC (PSU-ASIC) disconnects the supply voltage from the base band part of
the circuit. Only a voltage regulator in the PSU-ASIC is active for powering the
RTC. Software is not active. The serial interfaces are not accessible. Operating
voltage remains applied.
4.1.3 Alarm mode

6 Getting started
WARNING: Changing the baud rate of the GSM modem with AT+IPR disables
the USB-Serial link. If you change the baud rate of the GSM
modem inside the SAMBA55/56 (with AT+IPR=xxx) you can not
access the modem over our windows drivers anymore at all. The
driver internally always connects with 115200 baud - this setting
can not be changed by the user!!!
You only need to change the baud rate of the terminal or the
external used application which communicates with the
SAMBA55/56.
6.1 Installing your SAMBA in a Laptop computer running

7.2 RF Exposures
This device contains 1800 MHz GSM functions that are not operational in
U.S. Territories. This filing is only applicable for 850MHz GSM/1900 MHz
PCS operations.
This device and its antenna must not be co-located or operating in
conjunction with any other antenna or transmitter.
Statement according to FCC part 15.19:
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
Statement according to FCC part 15.105:
NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help
RF exposure FCC:
Tests for SAR are conducted using standard operating positions specified
by the FCC with the phone transmitting at its highest certified power level
in all tested frequency bands.
This confidential document is the property of FALCOM GmbH and may not be copied or circulated without permission.
Page 33
SAMBA 55/56 VERSION 1.07
Although the SAR is determined at the highest certified power level, the
actual SAR level of the phone while operation can be well below the
maximum value. This is because the phone is designed to operate at
multiple power levels so as to use only the power required to reach the
network. In general, the closer you are to a wireless base station antenna,
the lower the power output. Before a phone model is available for sale to
the public, it must be tested and certified to the FCC that it does not exceed
the limit established by the government-adopted requirement for safe
exposure. The tests are performed in positions and locations (e.g., at the ear
and worn on the body) as required by the FCC for each model. (Body-worn
measurements may differ among phone models, depending upon available
accessories and FCC requirements). While there may be differences
between the SAR levels of various phones and at various positions, they all
meet the government requirement for safe exposure. For body worn
operation, to maintain compliance with FCC RF exposure guidelines, use
only accessories that contain no metallic components and provide a
separation distance of 5mm (0.2 inches) to the body. Use of other
accessories may violate FCC RF exposure guidelines and should be
voided.
Health and Safety Information FCC:
Exposure to Radio Frequency (RF) Signals Your GSM/GPRS-Stick-Phone
is a radio transmitter and receiver. It is designed and manufactured not to
exceed the emission limits for exposure to radio frequency (RF) energy set
by the Federal Communications Commission of the U.S. Government.
These limits are part of comprehensive guidelines and establish permitted
levels of RF energy for the general population. The guidelines are based on
the safety standards previously set by both U.S. and international standards
bodies:
This EUT has been shown to be capable of compliance for localized
specific absorption rate (SAR) for uncontrolled environment/general
population exposure limits specified in ANSI/IEEE Std. C95.1-1992 and
had been tested in accordance with the measurement procedures specified
in FCC/OET Bulletin 65 Supplement C (2001) and IEEE Std. 1528-2003
December 2003).
The standards include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health. The exposure standard
for wireless mobile phones employs a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit set by the FCC is
1.6W/kg
*
.
7.3 Instructions to OEM
This manual includes specific warnings and cautions in order to ensure that
OEMs are aware of their responsibilities, with regards to RF exposure
compliance, for products into which the modem is integrated. With this
*
In the U.S. and Canada, the SAR limit for mobile phones used by the public is
1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard
incorporates a substantial margin of safety to give additional protection for the
public and to account for any variations in

guidance, the OEM will be able to incorporate into their documentation the
necessary operating conditions and warnings.
OEMs need to provide a manual with the “final” product that clearly states
the operating requirements and conditions and that these must be observed
to ensure compliance with current FCC RF exposure requirements / MPE
limits. This will enable the OEM to generate (and provide the end-user with)
the appropriate operating instructions, warnings and cautions, and/or
markings for their product.
7.4 Troubleshooting
In the unlikely event that you have problems using your SAMBA phone, the
following may solve or help to identify the problem; if not, if you have
access to the Internet for more technical support the Falcom Web pages at
“http://www.falcom.de/service/” have additional information about the
SAMBA phone.
1. General Checks
If SAMBA phone does not appear to be working correctly:
Check there is a SIM installed and a headset for voice calls is also
connected.
The delivered driver must be installed before begin to work.
Check if the USB connector is properly plugged.
If the modem status indicators (labelled ERR) continually light:
Maybe, the included USB driver which allocate a USB serial port is
not installed to the control host device yet, if that is true, disconnect
the SAMBA from host device and plug it again, and then install the
included driver.
If the modem does not response to the terminal program:
Check if the USB connector is properly plugged.
Disconnect it and connect it again.
2. It does not work when I travel.
To use a GSM network outside your own country your account
needs to be enabled for International Roaming. If this has not been
down, contact your GSM provider.
When in regions where GPRS is not available, a user can still access
their important information with GSM 14.4 kbps data connections.
3. I can not make data or fax calls
Some GSM networks require your SAMBA phone account to be
enabled for data and/or fax. If you do not know whether this applies to
you, please check with your GSM provider.
4. I can not receive data or faxes
Check your application is running. To receive faxes you will need
special software, for example, WinFax™ software.

Page 35
SAMBA 55/56 VERSION 1.07
Most GSM networks supply different phone numbers for voice, fax
and data. Contact your GSM provider for the numbers and ensure
that the fax and data calls being made to these, not to the voice call
number.
5. GPRS connection is slow and unstable
Disconnect and connect again. You may be switched to a better
network trunk line with better communication quality.
If the problem persists, avoid using GPRS connection during the
time when network traffic is heavy, or move to a location where
signal reception is better.
6. Can not use certain call functions
To use some advanced call functions (such as call divert, call barring or
call waiting), you need to subscribe them to your operator.
7. There is noise during a call
Avoid using the SAMBA phone near a TV, microwave oven,
speaker or other devices that emits strong electromagnetic energy.
Is the reception of signal in good condition? If not, move to a
location where signal reception is better.
