Chapter 6 – Application ConsiderationsMulti-Tech Systems, Inc. SocketModem CDMA Developer’s Guide 14Chapter 6 – ApplicationConsiderationsGeneral Guidelines for the Use of the SocketModemHardware and RF· Ground plane: Multi-Tech recommends having a common ground plane for analog, digital, andRF grounds.· ESD protection on serial link, …· Possible spurious emission radiated by the application to the RF receiver in the receiver bandThe AntennaThe antenna sub-system and integration in the application is a major issue. It is a major issue in thechoice of the antenna cable (type, length, performances, thermal resistance, etc.)These elements could affect CDMA performances such as sensitivity and emitted power.The antenna should be isolated as much as possible from the digital circuitry including the interfacesignals.Multi-Tech recommends shielding the terminal. On terminals including the antenna, a poor shielding coulddramatically affect the sensitivity of the terminal. Subsequently, the power emitted through the antennacould affect the application.Soldering and Cleaning the SocketModemThe pins of the SocketModem may be hand soldered or wave soldered. If wave soldered, the temperatureon the top of the SocketModem must not exceed 100° C.There should be no solvent or water washing of the SocketModem.Do not use a hot air gun on the SocketModem.Firmware UpgradeThe SocketModem firmware is stored in flash memory, and it can easily be upgraded. Contact the factoryfor details.Initial Configuration Using Mobile PhoneToolsFor initial configuration of your wireless device, Multi-Tech offers a Windows-based mobile PhoneToolsapplication.To load Mobile PhoneTools, click the Mobile PhoneTools icon on the system CD and follow the on-screenprompts.
Appendix A – Safety Precautions and Regulatory Standards ComplianceMulti-Tech Systems, Inc. SocketModem CDMA Developer’s Guide 15Appendix A – Safety Precautions &Regulatory Standards ComplianceSafety PrecautionsIMPORTANT!FOR THE EFFICIENT AND SAFE OPERATIONOF YOUR CDMA INTEGRATED MODEMREAD THIS INFORMATION BEFORE USE.RF SafetyGeneralYour SocketModem is based on the CDMA standard for cellular technology. Your modem is actually a lowpower radio transmitter and receiver. It sends out and receives radio frequency energy. When you useyour SocketModem integrated modem, the cellular system, which handles your calls controls both theradio frequency and the power level of your cellular modem.Exposure to RF EnergyThere has been some public concern about possible health effects of using CDMA modems. Althoughresearch on health effects from RF energy has focused on the current RF technology for many years,scientists have begun research regarding newer radio technologies, such as CDMA. After existingresearch had been reviewed, and after compliance to all applicable safety standards had been tested, ithas been concluded that the product was fitted for use. If you are concerned about exposure to RFenergy there are things you can do to minimize exposure. Obviously, limiting the duration of your calls willreduce your exposure to RF energy. In addition, you can reduce RF exposure by operating your cellularmodem efficiently by following the below guidelines.Efficient Modem OperationFor 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 callwith the antenna retracted. However your modem operates more efficiently with the antenna fullyextended.· Do not hold the antenna when the modem is IN USE. Holding the antenna affects call quality andmay cause the modem to operate at a higher power level than needed.Antenna Care and ReplacementDo 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 youmay change the antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, haveyour antenna repaired by a qualified technician. Use only the supplied or approved antenna.Unauthorized antennas, modifications, or attachments could damage the modem and may contravenelocal RF emission regulations or invalidate type approval.
Appendix A – Safety Precautions and Regulatory Standards ComplianceMulti-Tech Systems, Inc. SocketModem CDMA Developer’s Guide 16General SafetyDrivingCheck the laws and the regulations regarding the use of cellular devices in the area where you have todrive as you must comply with these laws and regulations. When using your modem while driving, pleasegive full attention to driving. Pull off the road and park before making or answering a call if drivingconditions so require.Electronic DevicesMost electronic equipment, for example in hospitals and motor vehicles, is shielded from RF energy.However, RF energy may affect some improperly shielded electronic equipment.Vehicle Electronic EquipmentCheck your vehicle manufacturer representative to determine if any on-board electronic equipment isadequately shielded from RF energy.Medical Electronic EquipmentConsult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc.) todetermine if they are adequately shielded from external RF energy. Turn your modem OFF in health carefacilities when any regulations posted in the area instruct you to do so. Hospitals or health care facilitiesmay be using RF monitoring equipment.AircraftTurn your modem 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) regulationsrequire you to have permission from a crew member to use your modem while the aircraft is on theground. To prevent interference with cellular systems, local RF regulations prohibit using your modemwhile airborne.ChildrenDo not allow children to play with your modem. It is not a toy. Children could hurt themselves or others (bypoking themselves or others in the eye with the antenna, for example). Children could damage themodem or make calls that increase your modem bills.Blasting AreasTo avoid interfering with blasting operations, turn your unit OFF when in a “blasting area” or in areasposted “turn off two-way radio”. Construction crews often use remote control RF devices to set offexplosives.Potentially Explosive AtmospheresTurn your modem OFF when in any area with a potentially explosive atmosphere. It is rare, but yourmodem or its accessories could generate sparks. Sparks in such areas could cause an explosion or fireresulting in bodily injuries or even death. Areas with a potentially explosive atmosphere are often, but notalways, clearly marked. They include fueling areas such as gas stations; below deck on boats; fuel orchemical transfer or storage facilities; and areas where the air contains chemicals or particles, such asgrain, dust, or metal powders. Do not transport or store flammable gas, liquid, or explosives, in thecompartment of your vehicle, which contains your modem or accessories. Before using your modem in avehicle powered by liquefied petroleum gas (such as propane or butane) ensure that the vehicle complieswith the relevant fire and safety regulations of the country in which the vehicle is to be used.
Appendix A – Safety Precautions and Regulatory Standards ComplianceMulti-Tech Systems, Inc. SocketModem CDMA Developer’s Guide 17General Safety StandardsTHIS WIRELESS SOCKETMODEM COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS.This cellular modem meets the standards and recommendations for the protection of public exposure toRF electromagnetic energy that have been established by governmental bodies and other qualifiedorganizations, such as the following:· Directives of the European Community,· Directorate General V in Matters of Radio Frequency Electromagnetic EnergyRF ExposuresPursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS)equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), §2.1091 and § 2.1093 as appropriate.The Multi-Tech SocketModem is a CDMA (PCS 1900) terminal which operates in the US licensed PCSfrequency spectrum. The device transmits over the 1850-1910 MHz band and receives over the 1930-1990 MHz Band. Multi-Tech Systems, Inc. certifies that it has determined that the Modem complies withthe RF hazard requirements applicable to broadband PCS equipment operating under the authority of 47CFR Part 24, Subpart E of the FCC Rules and Regulations. This determination is dependent uponinstallation, operation, and use of the equipment in accordance with all instructions provided.The modem is designed for and intended to be used in fixed and mobile applications. "Fixed" means thatthe device is physically secured at one location and is not able to be easily moved to another location."Mobile" means that the device is designed to be used in other than fixed locations and generally in sucha way that a separation distance of at least 20 cm is normally maintained between the transmitter'santenna and the body of the user or nearby persons. The Modem is not designed for or intended to beused in portable applications (within 20 cm of the body of the user) and such uses are strictly prohibited.To ensure that the unit complies with current FCC regulations limiting both maximum RF output powerand human exposure to radio frequency radiation, a separation distance of at least 20 cm must bemaintained between the unit's antenna and the body of the user and any nearby persons at all times andin all applications and uses. Finally, the tune-upprocedure for the O9EM2113 ensures that the maximum RF output power of the device does not exceed30.0 dBm within the variations that can be expected due to quantity production and testing on a statisticalbasis.Instructions to OEMsThe Multi-Tech product manual includes specific warnings and cautions in order to ensure that OEMs areaware of their responsibilities, with regards to RF exposure compliance, for products into which themodem is integrated. With this guidance, the OEM will be able to incorporate into their documentation thenecessary operating conditions and warnings.OEMs need to provide a manual with the ‘’final’’ product that clearly states the operating requirementsand conditions and that these must be observed to ensure compliance with current FCC RF exposurerequirements / MPE limits (see the “RF Exposures” section above). This will enable the OEM to generate(and provide the end-user with) the appropriate operating instructions, warnings and cautions, and/ormarkings for their product.
