1.3.2 SAR requirements specific to portable mobiles
Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module
must be in accordance with the guidelines for human exposure to radio frequency energy. This
requires the Specific Absorption Rate (SAR) of portable BGS2-E/BGS2-W based applications
to be evaluated and approved for compliance with national and/or international regulations.
Since the SAR value varies significantly with the individual product design manufacturers are
advised to submit their product for approval if designed for portable use. For European and US
markets the relevant directives are mentioned below. It is the responsibility of the manufacturer
of the final product to verify whether or not further standards, recommendations or directives
are in force outside these areas.

1.3.3 Safety Precautions
The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating BGS2-E/BGS2-W. Manufacturers of the cellular terminal are advised to convey the following safety information to users
and operating personnel and to incorporate these guidelines into all manuals supplied with the
product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Cinterion Wireless Modules assumes no liability for
customer’s failure to comply with these precautions.
When in a hospital or other health care facility, observe the restrictions on the use of
mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close
to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker
patients are advised to keep their hand-held mobile away from the pacemaker, while
it is on.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is
forbidden to prevent interference with communications systems. Failure to observe
these instructions may lead to the suspension or denial of cellular services to the
offender, legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or
fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots,
chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while
switched on. Remember that interference can occur if it is used close to TV sets,
radios, computers or inadequately shielded equipment. Follow any special regulations
and always switch off the cellular terminal or mobile wherever forbidden, or when you
suspect that it may cause interference or danger.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for speakerphone operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard.
IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellular networks.
Because of this, connection cannot be guaranteed at all times under all conditions.
Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls.
Remember, in order to make or receive calls, the cellular terminal or mobile must be
switched on and in a service area with adequate cellular signal strength.
Some networks do not allow for emergency calls if certain network services or phone
features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate
those features before you can make an emergency call.
Some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.

Confidential / Released
3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to in the following
chapters.
Table 7: Overview of operating modes
Normal operation 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=7 and 9 alternatingly
activate and deactivate the AT interfaces to allow permanent access to all AT commands.
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.
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.
GPRS IDLE Module is ready for GPRS data transfer, but no data is cur-
rently sent or received. Power consumption depends on
network settings and GPRS configuration (e.g. multislot settings).
GPRS DATA GPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control level),
uplink/downlink data rates, GPRS configuration (e.g. used
multislot settings) and reduction of maximum output power.
Power Down Normal shutdown after sending the AT^SMSO command.
Only a voltage regulator is active for powering the RTC. Software is not active.
Interfaces are not accessible.
Operating voltage (connected to BATT+) remains applied.
Alarm mode Restricted operation launched by RTC alert function while the module is in Power
Down mode. Module will not be registered to GSM network. Limited number of AT
commands is accessible.

4 Antenna Interface
The RF interface has an impedance of 50Ω. BGS2-E/BGS2-W is capable of sustaining a total
mismatch at the antenna lines without any damage, even when transmitting at maximum RF
power.
The external antenna must be matched properly to achieve best performance regarding radiated power, modulation accuracy and harmonic suppression. Antenna matching networks are
not included on the BGS2-E/BGS2-W module and should be placed in the host application if
the antenna does not have an impendance of 50Ω.
Regarding the return loss BGS2-E/BGS2-W provides the following values in the active band:

5.2 Operating Temperatures
Please note that the module’s lifetime, i.e., the MTTF (mean time to failure) may be reduced, if
operated outside the restriced temperature range. A special URC reports whether the module
enters or leaves the restriced temperature range (see [1]; AT^SCTM).
Note that within the specified operating temperature ranges the board temperature may vary
to a great extent depending on operating mode, used frequency band, radio output power and
current supply voltage.
When data are transmitted over GPRS the quad band module variant automatically reverts to
a lower Multislot Class if the temperature rises to the limit specified for normal operation and,
vice versa, returns to the higher Multislot Class if the temperature is back to normal.
