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.

Page 8
SAMBA 55/56 VERSION 1.03
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
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.

SAMBA 55/56 VERSION 1.03
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
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 nonradiating 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.

3.2 Functional description
The GSM/GPRS modem SAMBA is a mobile station for transmission of
voice, data and fax calls as well as SMS in GSM networks.
The GSM/GPRS modem SAMBA consists of the following components:
• GSM/GPRS transceiver
• USB 1.1 for power supply, data transmission and control.
• GPRS Class B, class 10.
The GSM/GPRS modem SAMBA allows control of the GSM/GPRS
modem over the interface A.
If the GSM/GPRS modem SAMBA is registered in the network, it acts just
like a regular fax/data modem. To control the GSM or GSM/GPRS Modem
there is an advanced set of AT-commands according to GSM ETSI 07.07
and 07.05 implemented.
The actual state of the SAMBA is displayed by three LED’s on the interface

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. 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).
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).

6.1.1 Getting started to GPRS Network
This section with following instructions are available only for SAMBA
versions providing GPRS Class-B.
What is GPRS:
GPRS is a complete new part of the existing GSM network.
GPRS is packed switched high speed mobile data.
GPRS is an efficient approach to upgrade the existing GSM to a
packet switched system.
GPRS is an important step in direction to mobile internet.
What you need to accomplished connection to the GPRS network ?
GPRS settings from your network provider
- APN (name of access point that connects the mobile network to
the Internet)
- Primary and secondary DNS (Domain Name Server)
- IP header compression
- IP address (DHCP or static)
- User name and password (may be optional)
- Dial number
Modem installation and configuration
Dial-Up Network installation and configuration
What does the GPRS Class 10, Class B mean ?
GPRS Class 10:
- Mobile telephones differ in the number of channels that they can
bundle. The reason for this is simple. The more time slices
allocated, the more energy consumed by the device sending the
signal. The higher is the GPRS class, the higher is the data speed
(transfer or receive). The highest class of GPRS (Global Packet
Radio Service) you have, the more efficient services you get.
Class 10 means the ability to manage 4 time slots for downloads
or 2 time slots for uploads simultaneously. Today, class 10 is the
highest class used for mobile phones.
GPRS Class B:
- The definition of mobile telephones supporting GPRS class B is,
that the mobile telephones can be attached to both GPRS and
other GSM services, but the mobile telephones can support either
a voice connection or a data connection. Trying to establish a
simultaneous connection with both does not work. Switching
between one service and the other happens automatically.
6.1.1.1 Making a dial-up networking
This brief guide aims to explain the basic steps for getting started with
GPRS to the internet. It is supposed that you are a bit familiar with GPRS
concepts, like network attachment, session or PDP context.

Page 31
SAMBA 55/56 VERSION 1.03
This guide is not intended to give full details about how GPRS works, all
GPRS-specific AT commands (check out the GPRS AT command manual).
The GPRS AT command manual is available on the Falcom’s Website for
download:
http://www.falcom.de/services/download/Falcom_SAMBA
6.1.2 Communications software
To connect to the Internet, or to send and receive e-mail or faxes transmit
data from your computer, you need the appropriate data and fax
communications software. You can use the SAMBA modem with most
commercially available communications applications, such as Microsoft
Exchange, Microsoft Outlook, Netscape Navigator.
6.1.3 PIN & PUK
You may have to enter the PIN (Personal Identity Number) if the PIN code
request is activated in the SIM card. The PIN code is usually supplied with
the SIM card. If you enter an incorrect PIN code three times in a row, you
will need a PUK (Personal Unblocking Key) code to unblock the SIM card.
The PUK code may be supplied with the SIM card. If not, contact your
service provider. For more details about using the SAMBA please read
carefully the chapters below.
6.1.4 Text messages
The Short Message Service (SMS) is a network service that enables you to
send and receive short text messages over the digital cellular network.
Messages can be read on any mobile phone that has SMS capability.
The sending and receiving of text messages requires that the Short Message
Service (SMS) be available in the network you are using and activated for
your SIM card. Contact your service provider for details. Before you can
send text messages, you must store the SMS message centre number in the
Settings window, Messages tab. The included software supports also a
comprehensive overview, and an easy and quickly way to start up this
application when the SAMBA is already registered into the GSM network.

available as an included accessory (see chapter "Package contents"). The
included software supports also an easy and quick way to start up this
application when the SAMBA is already registered into the GSM network.
6.1.6 Data and fax communication
The SAMBA phone provides the functionality of a cellular modem. To send
and receive e-mail and faxes, connect to remote computers and access the
Internet, you also need the appropriate data and fax communications
software. You can use the SAMBA phone with a variety of commercially
available Windows 98, Windows NT 40, Windows 2000 and XP compatible
data and fax communications applications. These applications must be
correctly configured for use with the SAMBA phone, according to the
instructions given in the documentation of these applications and your
computer. Remember to select the SAMBA phone as the modem in each
application. The data transfer and fax functions depend on the applications
you have chosen, not on the computer or the SAMBA phone. For
information on how to use an application, please refer to that application's
documentation. The SAMBA phone supports three PC Fax standards.
EIA/TIA Class 1, Class 2. lf you have problems with using the SAMBA
phone for fax transmissions, make sure that the remote end fax machine is
Group 3 compatible. The SAMBA phone can also be controlled with AT
Commands. For more information, refer to the AT-Command manual,

There are three possible response of SAMBA:
+CGREG:0,1 means the SAMBA is successfully attached.
+CGREG:0,0 means the SAMBA is trying to attach.
+CGREG:0,2 has failed to attach and stopped trying to attach.
This occurs approx. within 1-3 min of powering up.
+CGREG:0,3 Registration denied. The GPRS service is disabled,
the MS is not allowed to attach for GPRS if
requested by the user.
+CGREG:0,4 unknown
+CGREG:0,5 Registered, roaming
Alternatively, the registration status can be retrieved using:
AT+CGATT?
There are two possible response of SAMBA:
+CGATT:1 means the MS is successfully attached.
+CGATT:0 means the MS is not attached, or has failed to attach.
This command is somewhat less accurate than AT+CGREG?.

7.5 Examples: Using Class-B functionality via the serial interface
This chapter provides step-by-step instructions of how to make use of the
mobiles Class-B capabilities in a Network Operation Mode II (NOM II) or
Network Operation Mode I (NOM I) network. The examples proceed from
the fact that the MS is already in PPP online mode and either engaged in a
GPRS data transaction (= in PTM) or not engaged (= not in PTM). While
the SAMBA is in PTM, GSM calls can only be accepted if the network is
type NOM I.
For using the Class-B functionality the Multiplex Mode is not necessary.
The scenarios described below are executed on one single logical channel.
Please note that URCs, for example .RING. can only be displayed if the
SAMBA is in command mode.
1. Making a voice call while MS is in PPP online mode, but not in
PTM
Use +++ to change from PPP online mode to command mode
Set up a voice call with ATD<target number>;
End the voice call with AT+CHLD=1
Go back to PPP online mode with ATO
2. Making a CSD / fax call while MS is in PPP online mode, but not in
PTM
Use +++ to change from PPP online mode to command mode
Set up a CSD call with ATD< target number>
After the CSD / fax call was established, change from data mode to
command mode with +++
End the CSD / fax call with AT+CHLD=1
Go back to PPP online mode with ATO
3. Answering a voice call while MS is in PPP online mode, but not in
PTM

Accept the voice call with ATA or reject with AT+CHLD=0
After the voice call was accepted, you can end the voice call with
AT+CHLD=1
Go back to PPP online mode with ATO
4. Answering a CSD / fax call while MS is in PPP online mode, but not
in PTM
Hardware ring indicates incoming data call
Use +++ to change from PPP online mode to command mode
URC .RING. is displayed
Accept the data call with ATA or reject with AT+CHLD=0

command mode with +++
You can end the data call with AT+CHLD=1
Go back to PPP online mode with ATO
1. Answering a voice call while MS is in PPP online mode and in PTM
This scenario can only be ensured in Network Operation Mode I,
since Paging Coordination is necessary1).

When you attempt to follow these steps in a NOM II network, be aware that the .RING.
URC usually does not appear since no Paging coordination is done in PTM. However, in a
bursty traffic flow where data packets are transferred discontinuously paging messages
and, thus, the .RING. URC, may be received. In this case, the scenarios 5) and 6) might be
successful even though the network only supports NOM II

7.6 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.
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. (Bodyworn 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

7.7 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
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.
*
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

7.8 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.
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.

SAMBA 55/56 VERSION 1.03
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.
