Smart Machine Smart Decision SIM5320AD EVB User Guide 02.04.2011 176 Quickly start 6.1 Running There are two ways to provide power supply to SIM5320AD module: one is to use the 6V power supply provided in the EVB kit; the other is to use USB port of personal computer. (1) When user use the power supply, if user insert 6V DC source adapter, user should connect ADAPTER_VBAT pin and VBAT pin on the EVB board; then insert a valued SIM card and check if the antenna is connected, and make sure that RF control switch is set to ON; finally press the on/off switch for about 1 second, and then SIM5320AD module will begin running. (2) Another option is to use USB port of Computer as power supply. To do so, user need to connect USB_VBAT pin and VBAT pin on the EVB board, and make sure that RF control switch is set to ON. Firstly insert the sim card and connect the antenna, then connect the PC with USB-to-USB cable and press the Power_ON button for one second, then SIM5320AD will start running. User can see the light on the EVB flashing at a certain frequency about 1.25Hz. By the state, user can judge whether the EVB and SIM5320AD is running or not. No function and test can be executed if user has not connected necessary accessories. NOTE: This EVB board supports USB power supply when user connects USB_VBAT and VBAT together. 6.2 Installing Driver There are 3 ways to connect the module to user’s computer and communicate via HyperTerminal: (1) Using USB-TO-USB cable; (2) Using UART-TO-USB cable; (3) Using UART-TO-UART cable. In the first case, user need install the module USB driver, which can be got from our FAE or sales; For the UART to USB driver, user may get it from the CD in the EVB kit; If user use UART to UART cable, there are certain points to be noticed. One can use UART to UART cable in EVB kit, if the customers want to use their own UART to UART cable, please make sure that the pin sequences of it is same as those of cable in EVB kit, pin sequences of which are shown in Figure 9.
Smart Machine Smart Decision SIM5320AD EVB User Guide 02.04.2011 186.3 Connecting Net and calling Once user installs the driver, user can follow steps below to connect to Network. (1) When user use a UART-UART cable, user need to connect the serial port line to the serial port, open the HyperTerminal (AT command windows) on user’s Personal computer. The location of the HyperTerminal in windows2000/XP/Vista can be found from START→accessory→ communication→HyperTerminal. Please set the correct Baud Rate and COM port number, the Baud Rate of SIM5320AD is 115200, and the COM port number is based on which UART port user’s serial port line is inserted, user should select the port such as COM1 or COM2 etc. (2) Connect the antenna to the SIM5320AD module using an antenna transmit line, insert SIM card into the SIM card holder, and insert handset into its sockets. (3) Follow the steps of running which has been mentioned above in Sector 5.1, power on the system, type the AT command from the HyperTerminal, and then the SIM5320AD module will execute its corresponding function. For example, if user type “AT”, then it should respond “OK”; if user type “ATI”, it should display product identification information. (4) If user want to use USB to USB cable, user need to connect the cable to USB port of the module and the computer, then follow step 1~3. (5) If user use UART to USB cable, user need to connect the cable to module serial port and the USB port of the computer, then follow step 1~3. 6.4 Downloading Connect the USB port line to the USB port, connect the direct current source adapter, run the download program, and choose the correct image, please follow the QDL downloading menu for the operation. Update procedure is described in the figure below.

Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 182.4 Footprint Recommendation Figure 6: Footprint recommendation (Unit: mm) 3 Application Interface Specification 3.1 Power Supply The power supply pins of SIM5320AD include VBAT_RF and VBAT_BB. VBAT_RF directly supplies the power to RF PA; VBAT_BB supplies the power to the baseband system. For the VBAT_RF, the ripple due to GSM/GPRS emission burst (every 4.615ms）may cause voltage drop, and the current consumption rises typically to peak of 2A. So the power supply must be able to provide sufficient current up to 2A. The following figure is the VBAT_RF voltage ripple wave at the maximum power transmit phase. The test condition: VBAT_RF=4.0V, VBAT maximum output current =2A, CA=100 µF tantalum capacitor (ESR=0.7Ω) and CB=1µF(Please refer to Figure 36—Application circuit).
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 19 Figure 7: VBAT_RF voltage drop during burst emission (GSM/GPRS) 3.1.1 Power Supply Pin Two VBAT_RF and two VBAT_BB pins are dedicated to connect the supply voltage. Table 4: Pin description Pin type Pin name Min Typ Max Unit VBAT_RF 3.3 3.8 4.2 V POWER VBAT_BB 3.3 3.8 4.2 V Note: 1.Though the VBAT_RF and VBAT_BB are supplied by the same voltage level, they are different pins. VBAT_RF is for RF section and VBAT_BB is for baseband system. 2. When the module is power off, users must pay attention to the issue about current leakage. Refer to Chapter 3.10.2 Note2. 3.1.2 Design Guide Mostly, user connects the VBAT_RF and VBAT_BB pins with one power supply. Make sure that the input voltage at the VBAT_BB pin will never drop below 3.3V even during a transmit burst when the current consumption rises up to 2A. If the power voltage drops below 3.3V, the module may be shut down automatically. Using a large tantalum capacitor (above 100uF) will be the best way to reduce the voltage drops. If the power current cannot support up to 2A, users must introduce larger capacitor (typical 1000uF) to storage electric power, especially GPRS multiple time slots emission. For the consideration of RF performance and system stability, another large capacitor (above 100uF) should be located at the VBAT_RF pin and some multi-layer ceramic chip (MLCC) capacitors (0.1uF) need to be used for EMC because of their low ESR in high frequencies. Note that capacitors should be put beside VBAT_RF pins as close as possible. Also User should minimize the PCB trace impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the board. The following figure is the recommended circuit.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 20 Figure 8: VBAT input application circuit There are three sections about how to design and optimize users’ power systems. Power supply circuit We recommend DCDC or LDO is used for the power supply of the module, make sure that the peak current of power components can rise up to 2A. The following figure is the reference design of +5V input power supply. The designed output for the power supply is 4.1V, here a linear regulator can be used.

The following figure is the reference circuit. Note that DCDC may deprave RF performance because of ripple current intrinsically.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 21 Figure 10: Reference circuit of the DCDC power supply Voltage monitor To monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has two parameters: the battery status and the voltage value (mV). It will return the capacity percentage and actual value of battery (at the VBAT_BB pin). The voltage is continuously measured at intervals, whenever the measured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”. For example, if the voltage value is set to be 3.4V, the following URC will be presented: “warning! voltage is low: 3.3v”. If the voltage is lower than a specific value which is set by the AT command “AT+CPMVT”, the module will be powered off automatically and AT commands cannot be executed any more. Note: Under-voltage warning function is disabled by default, user can enable it by the AT command “AT+CVALARM”. Auto power off feature is disabled by default, user should set it by the AT command “AT+CPMVT” to an appropriate value. Please refer to Document [1]. 3.1.3 RTC Backup The module uses RTC (Real Time Clock) to update and maintain inherent time and keeps system alive at no power supply status. The RTC power supply of module can be provided by an external capacitor or a battery (non-chargeable or rechargeable) through the VRTC. The following figures show various reference circuits for RTC back up. The discharge current is less than 10uA. If this feature is used, please refer to the AT commands “AT+CTZU” and “AT +CTZR”. z External capacitor backup

POWER_ON pin is pulled up with a 200kR resistor to 1.8V in module. User can power on the SIM5320AD by pulling the POWER_ON pin down for a short time. The power-on scenarios are illustrated in the following figures.

These procedures will make module disconnect from the network and allow the software to enter a safe state, and then save data before completely powering the module off. ● Method 1: Power off SIM5320AD by pulling the POWER_ON pin down ● Method 2: Power off SIM5320AD by AT command User can power off the SIM5320AD by pulling POWER_ON down for a specific time. The power off scenario is illustrated in the following figure.

After that, the AT commands cannot be executed any longer. The module enters the POWER DOWN mode, only the RTC is still active. For details, refer to Document [1]. 3.3 UART Interface SIM5320AD provides a UART (universal asynchronous serial transmission) port. It consists of a flexible 7-wire serial interface. The module is as the DCE (Data Communication Equipment) and the client PC is as the DTE (Data Terminal Equipment). AT commands are entered and serial communication is performed through UART interface. The application circuit is in the following figures.

All pins of all serial ports have 8mA driver capacity. 3.3.2 Application Guide If UART port is used in Null Modem, the pin “RI” can be used as an interrupt signal to HOST. Normally it will keep high logic level until certain condition such as receiving SMS, voice call (CSD, video) or URC reporting, then “RI” will change to low logic level to inform the master (client PC). It will stay low until the master clears the interrupt event with AT command. Figure 20: RI behaviour in NULL Modem If Full Modem is used to establish communication between devices, the pin “RI” is another operation status. Initially it keeps high, when a voice call or CSD call comes, the pin “RI” will change to low for about 5900ms, then it will return to high level for 100ms. It will repeat this procedure until this call is answered or hung up.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 29 Figure 21: RI behaviour in FULL Modem To comply with RS-232 protocol, the RS-232 level shifter chip should be used to connect SIM5320AD to the RS-232-C interface. In this connection, the TTL level and RS-232 level are converted mutually. SIMCom recommends that user uses the SP3238ECA chip with a full modem. For more information please refers to the RS-232 chip datasheet. Note: SIM5320AD supports the communication rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 3200000, 3686400, 4000000bps. Default rate is 115200bps. 3.4 USIM Interface The USIM provides the required subscription verification information to allow the mobile equipment to attach to a GSM or UMTS network.

Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 303.4.2 Application Guide It is recommended to use an ESD protection component such as ST (www.st.com ) ESDA6V1W5 or ON SEMI (www.onsemi.com ) SMF05C. Note that the SIM peripheral circuit should be close to the SIM card socket. The reference circuit of the 8-pin SIM card holder is illustrated in the following figure. Figure 22: USIM interface reference circuit Note: USIM_DATA has been pulled up with a 22kR resistor to V_USIM in module. A 220nF shut capacitor on V_USIM is used to reduce interference. Use AT Commands to get information in USIM card. For more detail, please refer to document [1]. 3.4.3 Recommend Components For 6 pins USIM socket, SIMCom recommend to use Amphenol C707 10M006 512 2.

Use AT Commands “AT+CRIIC and AT+CWIIC” to read/write register values of related peripheral equipments connected with I2C interface.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 323.5.1 Pin Description Table 12: Pin description 3.5.2 Signal Description Both SDA and SCL are bidirectional lines, connected to a positive supply via a pull-up resistor respectively. When the bus is free, both lines are high. 3.5.3 Design Guide For SIM5320AD, the data on the I2C bus can be transferred at rates up to 400kbps. The number of peripheral devices connected to the bus is solely dependent on the bus capacitance limit of 400pF. Note that PCB traces length and bending are in users’ control to minimize load capacitance. Note：I2C_SDA and I2C _SCL have been pulled up with two 2.2kR resistors to 2.6V level in module. So there is no need to pull them up in users’ application circuit. 3.6 USB Interface SIM5320AD module contains a USB interface. This interface is compliant with the USB2.0 specification. The USB2.0 specification requires hosts such as the computer to support all three USB speeds, namely low-speed (1.5Mbps), full-speed (12Mbps) and high-speed (480Mbps). USB charging and USB-OTG is not supported.

If no transaction is on USB bus, SIM5320AD will enter suspend mode. When some events such as voice call or receiving SMS happen, SIM5320AD will resume normal mode automatically. Figure 24: USB interface Because of high bit rate on USB bus, pay attention to influence of junction capacitance of ESD component on USB data lines. Typically, the capacitance should be less than 4pF @1MHz. Note：The SIM5320AD has two kinds of interface (UART and USB) to connect to host CPU. USB interface is mapped to five virtual ports: “SIMTECH USB Modem”, “SIMTECH NMEA Device”, “SIMTECH ATCOM Device”, “SIMTECH Diagnostics interface” and “SIMTECH Wireless Ethernet Adapter”. 3.7 SPI Interface SPI interface of SIM5320AD is master only.

When the module is powered off, make sure all digital interfaces (UART, etc) connected with peripheral devices have no voltage higher than 0.3V. If users’ design cannot meet above conditions, high level voltages maybe occur in GPIO pins because current leakage from above digital interfaces may occur.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 373.9 Global Positioning System SIM5320AD merges GPS satellite and network information to provide a high-availability solution that offers industry-leading accuracy and performance. This solution performs well, even in very challenging environmental conditions where conventional GPS receivers fail, and provides a platform to enable wireless operators to address both location-based services and emergency mandates. 3.9.1 Technical specification Tracking sensitivity -157 dBm Cold-start sensitivity -144 dBm Accuracy (Open Sky) <2m (CEP50) TTFF (Open Sky) Hot start <1s Cold start 35s（good signal）/ 100s(weak signal) Receiver Type 12-channel, GPS L1 Frequency (1575.42MHz), C/A Code Update rate Default 1 Hz GPS data format NMEA-0183 GPS Current consumption (WCDMA/GSM Sleep mode) 100mA (Total supply current) GPS antenna Passive/Active antenna Note: Performance will vary depending on the environment, antenna type and signal conditions and so on. 3.9.2 Operate Mode SIM5320AD supports both A-GPS and S-GPS, and then provides three operating modes: mobile-assisted mode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and mobile-based mode. In mobile-assisted mode, when a request for position location is issued, available network information is provided to the location server (e.g. Cell-ID) and assistance is requested from the location server. The location server sends the assistance information to the handset. The handset/mobile unit measures the GPS observables and provides the GPS measurements along with available network data (that is appropriate for the given air interface technology) to the location server. The location server then calculates the position location and returns results to the requesting entity. In mobile-based mode, the assistant data provided by the location server encompasses not only the information required to assist the handset in measuring the satellite signals, but also the information required to calculate the handset’s position. Therefore, rather than provide the GPS measurements and available network data back to the location server, the mobile calculates the location on the handset and passes the result to the requesting entity. In standalone (autonomous) mode, the handset demodulates the data directly from the GPS satellites. This mode has some reduced cold-start sensitivity, and a longer time to first fix as compared to the assisted modes. However, it requires no server interaction and works out of network coverage. This combination of GPS measurements and available network information provides:
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 38● High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural ● High availability that is enabled by using both satellite and network information Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell geometry/density, and while unassisted, GPS-only solutions typically perform poorly indoors. The SIM5320AD GPS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced network utilization in both of these environments, depending on the given condition. 3.9.3 Application Guide Users can adopt an active antenna or a passive antenna as GPS signal transceiver. In this document, all GPS specification mentioned is from passive antenna. The following is the reference circuit. Figure 27: Active antenna circuit Figure 28：Passive antenna circuit (Default) In above figures, the components C1 and L1, L2 are used for antenna matching, the values of the
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 39components can only be obtained after the antenna tuning usually, and they are provided by antenna vendor.C2 in Figure 27 is used for DC isolation. In active antenna circuit, users must use an external LDO/DCDC to provide VDD voltage whose value should be taken according active antenna characteristic, and VDD can be shut down to avoid consuming additional current when not being used. GPS can be used by NMEA port. User can select NMEA as output through UART or USB. NMEA sentences are automatic and no command is provided. NMEA sentences include GSV, GGA, RMC, GSA, and VTG. Before using GPS, user should configure SIM5320AD in proper operating mode by AT command. Please refer to related document for details. SIM5320AD can also get position location information through AT directly. Note:GPS is closed by default, it could be started by AT+CGPS. The AT command has two parameters, the first is on/off, and the second is GPS mode. Default mode is standalone mode. AGPS mode needs more support from the mobile telecommunication network. Refer to AGPS application document for details. 3.10 Multi-functional interface SIM5320AD merges functions for various applications. It can enrich users’ design and lower the cost of users’ hardware. 3.10.1 Sink Current Source The dedicated pin (CURRENT_SINK) is intended for driving passive devices，such as LCD backlight, this implementation is +5V tolerant and suitable for driving white LEDs. The high-current driver can maintain a constant current which is set by the AT command “AT+ CLEDITST”, capable of up to 150 mA. Table 20: Electronic characteristic Symbol Description Min Typ Max Unit CURRENT_SINK Input voltage 0.5 VDD 5 V IO Input current - - 150 mA Since the driver is ground-referenced current sink, the operating device it drives must form a current path between the VDD pin and the CURRENT_SINK pin. The following figure is for users reference.

This function is used as an emergency reset only when AT command “AT+CPOF” and the POWER_ON pin has no effect. User can pull the RESET pin to ground, then the module will reset. This pin is already pulled up in module, so the external pull-up resistor is not necessary. A 100nF capacitor close to the RESET pin is strongly recommended. A reference circuit is recommended in the following figure. Figure 30: Reset circuit Note：50ms<t<200ms. ESD components are suggested to be used on Reset pin. 3.10.3 ADC SIM5320AD has a dedicated ADC that is available for digitizing analog signals such as battery voltage

The data can be transformed to any type such as voltage, temperature etc. Please refer to Chapter 3.1.2 and document [1]. Figure 31: Reference circuit Note: The input signal voltage value in ADC must not be higher than 2.2V. 3.10.4 LDO SIM5320AD has a LDO power output, namely VREG_AUX. The LDO is available and output voltage is 2.85v by default, rated for 250mA. User can switch the LDO on or off by the AT command “AT+CVAUXS” and configure its output voltage by the AT command “AT+CVAUXV”.

Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 444.3 Antenna Design Guide SIM5320AD provides RF antenna interface. Customer’s antenna should be located in the host board and connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace impedance must be controlled in 50Ω. SIMCom recommends that the total insertion loss between the antenna pad and antenna should meet the following requirements: ● GSM900/GSM850<0.5dB ● DCS1800/PCS1900 <0.9dB ● WCDMA 1900<0.9dB ● WCDMA 850<0.5dB To facilitate the antenna tuning and certification test, a RF connector and an antenna matching circuit should be added. The following figure is the recommended circuit. Figure 32: Antenna matching circuit In this figure, the components R1,C1,C2 and R2 is used for antenna matching, the value of components can only be got after the antenna tuning, usually, they are provided by antenna vendor. By default, the R1, R2 are 0 ohm resistors, and the C1, C2 are reserved for tuning. The RF test connector in the figure is used for the conducted RF performance test, and should be placed as close as to the module’s antenna pin. The traces impedance between components must be controlled in 50ohm.

Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 465.2.1 Operating Modes Overview Table 31: Operating Modes Overview Mode Function Sleep mode GSM/WCDMA SLEEP Module will automatically enter SLEEP mode if DTR is set to high level and there is no on air or hardware interrupt (such as GPIO interrupt or data on serial port). In this case, the current consumption of module will be reduced to the minimal level. In SLEEP mode, the module can still receive paging message，voice call and SMS. GSM GSM IDLE Software is active. Module has registered to the GSM network, and the module is ready to communicate. GPRS STANDBY Module is ready for GPRS data transfer, but no data is currently sent or received. In this case, power consumption depends on network settings and GPRS configuration. GPRS GPRS DATA There is GPRS data transfer (PPP or TCP or UDP) in progress. In this case, power consumption is related with network settings (e.g. power control level), uplink/downlink data rates and GPRS configuration (e.g. used multi-slot settings). EDGE STANDBY Module is ready for data transfer in EDGE mode, but no data is currently sent or received. In this case, power consumption depends on network settings and EDGE configuration EDGE EDGE DATA There is EDGE data transfer (PPP or TCP or UDP) in progress. In this case, power consumption is related with network settings (e.g. power control level), uplink/downlink data rates and EDGE configuration. WCDMA WCDMA IDLE Module has registered to the WCDMA network, and the module is ready to communicate. HSDPA IDLE Module is ready for data transmission, but no data is currently sent or received. Power consumption depends on network settings and HSDPA configuration HSDPA HSDPA DATA There is HSDPA data transfer (PPP or TCP or UDP) in progress. In this case, power consumption is related with network settings (e.g. power control level), uplink/downlink data rates and HSDPA configuration Power down Module can be powered down by the AT command “AT+CPOF” or the POWER_ON pin. The power management unit shuts down the power supply of the module, only the power supply of RTC is remained. The serial interface is not accessible. Operating voltage (connected to VBAT) remains applied. Minimum functionality mode The AT command “AT+CFUN” can be used to set the module to a minimum functionality mode without removing the power supply. In this mode, the RF part of the module will not work or the SIM card will not be accessible, or both will be closed, and the serial port is still accessible. The power consumption in this mode is very low. 5.2.2 Minimize Power Consumption There are two modes that SIM5320AD achieves low power consumption.
Smart Machine Smart Decision SIM5320_Hardware Design_V1.01 2011-11-10 47Sleep mode If peripheral equipments stops working, and there is no on air or hardware interrupts (such as GPIO interrupts or data on UART), SIM5320AD will enter sleep mode automatically. In this mode, SIM5320AD can still receive paging，voice call or SMS from network. If USB interface of SIM5320AD is connected to host CPU, but host CPU does not support USB suspending, then SIM5320AD will not enter sleep mode. After USB is disconnected, SIM5320AD will enter sleep mode. Note: When UART interface is connected with host CPU, SIM5320AD can not enter sleep mode until RXD is pulled down by the host CPU. If the module is in the idle mode, make sure to pull the RXD to low level by host CPU. SIMCom recommends using GPIO43 or UART_DTR to wake up the module from host CPU and to use GPIO41 or UART_RI to wake up the host CPU. Before designing, pay attention to how to realize waking function and refer to Document[24] and Document[25] for more detail. Minimum functionality mode Minimum functionality mode ceases a majority function of module, thus minimizing the power consumption. This mode is set by the AT command which provides a choice of the functionality levels. ● AT+CFUN=0: Minimum functionality ● AT+CFUN=1: Full functionality (Default) ● AT+CFUN=4: Disable RF function of the module (Flight mode) If SIM5320AD has been set to minimum functionality mode, the module will firstly enter sleep mode, then the RF function and SIM card function will be closed. In this case, the serial port is still accessible, but RF function or SIM card will be unavailable. When SIM5320AD is in minimum functionality or flight mode, it can return to full functionality by the AT command “AT+CFUN=1”. Note: For flight mode, please refer to Chapter3.9.2. 5.3 Current Consumption The current consumption in suspended mode and without USB connection is listed in the table below. Here, “suspended mode” means that SIM5320AD is connected to USB bus, but it does not transfer data.

Possible harmful emissions radiate by the application to the RF receiver in the receiver band. It is recommended to shield the sensitive components and trace with common ground and user can add beads where necessary. Normally SIM5320AD is mounted on customer host board. Although some ESD components have been added in SIM5320AD, to prevent ESD, user should put some ESD components on customers’ board. The ESD components should be placed beside the connectors which human body might touch, such as SIM card holder, switches, keys, etc. The following table is the SIM5320AD ESD measurement performance; the results are from SIMCom EVB test.

Safety Caution Table 38: Safety caution Marks Requirements When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive to not operate normally for RF energy interference. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Forget to think much of these instructions may lead to the flight safety or offend against local 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. RF interference can occur if it is used close to TV sets, radios, computers or other electric equipment. 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 hands free operation. Before making a call with a hand-held terminal or mobile, park the vehicle. GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, for example no mobile fee or a invalid SIM card. While you are in this condition and need emergent help, please remember using emergency calls. 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 call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call. Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.
