Chapter 6 – Application ConsiderationsWireless ModemModule MTMMC-C Developer's Guide 18Chapter 6 – Application ConsiderationsGeneral Guidelines for the Use of the ModemModuleHardware and RF· Ground plane: Multi-Tech recommends having a common ground plane for analog, digital and RF grounds.· Bias of the Microphone inputs must be properly adjusted when using audio connectors (mic + speaker) 1.· EMC protection on audio input/output (filters against 900 MHz)· 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 the choice of theantenna 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 interface signals.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 antenna couldaffect the application.Firmware UpgradeThe ModemModule firmware is stored in flash memory, and it can easily be upgraded. Contact the factory fordetails.Initial Configuration Using Mobile PhoneToolsFor Initial configuration of your wireless device, Multi-Tech offers a Windows-based mobile PhoneToolsapplication.To load Mobile PhoneTools, click on the Mobile PhoneTools icon on the system CD and follow the on-screenprompts.

Appendix A – Safety Precautions & Regulatory Standards complianceWireless ModemModule MTMMC-C Developer's Guide 20Appendix A – Safety Precautions & RegulatoryStandards ComplianceSafety PrecautionsIMPORTANT!FOR THE EFFICIENT AND SAFE OPERATIONOF YOUR CDMA INTEGRATED MODEM READTHIS INFORMATION BEFORE USE.RF SafetyGeneralYour ModemModule 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 use yourModemModule integrated modem, the cellular system that handles your calls controls both the radio frequencyand the power level of your cellular modem.Exposure to RF EnergyThere has been some public concern about possible health effects of using CDMA modems. Although researchon health effects from RF energy has focused on the current RF technology for many years, scientists havebegun research regarding newer radio technologies, such as CDMA. After existing research had been reviewed,and after compliance to all applicable safety standards had been tested, it has been concluded that the productwas fitted for use. If you are concerned about exposure to RF energy there are things you can do to minimizeexposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In addition, youcan reduce RF exposure by operating your cellular modem 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 call withthe 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 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 minorburn may result. Replace a damaged antenna immediately. Consult your manual to see if you may change theantenna yourself. If so, use only a manufacturer-approved antenna. Otherwise, have your antenna repaired by aqualified technician. Use only the supplied or approved antenna. Unauthorized antennas, modifications orattachments could damage the modem and may contravene local RF emission regulations or invalidate typeapproval.
Appendix A – Safety Precautions & Regulatory Standards complianceWireless ModemModule MTMMC-C Developer's Guide 21General SafetyDrivingCheck the laws and the regulations regarding the use of cellular devices in the area where you have to drive asyou always have to comply with them. When using your modem while driving, please: give full attention todriving, pull off the road and park before making or answering a call if driving conditions so require.Electronic DevicesMost electronic equipment, for example in hospitals and motor vehicles is shielded from RF energy. However RFenergy may affect some improperly shielded electronic equipment.Vehicle Electronic EquipmentCheck your vehicle manufacturer representative to determine if any on-board electronic equipment is adequatelyshielded 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 facilities may beusing 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) regulations requireyou to have permission from a crewmember to use your modem while the aircraft is on the ground. To preventinterference with cellular systems, local RF regulations prohibit using your modem while 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 the modem, ormake calls that increase your modem bills.Blasting AreasTo avoid interfering with blasting operations, turn your unit OFF when in a « blasting area » or in areas posted: «turn off two-way radio ». Construction crews often use remote control RF devices to set off explosives.Potentially Explosive AtmospheresTurn your modem OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem orits accessories could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodilyinjuries or even death. Areas with a potentially explosive atmosphere are often, but not always, clearly marked.They include fueling areas such as petrol stations; below decks on boats; fuel or chemical transfer or storagefacilities; and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. Do nottransport or store flammable gas, liquid, or explosives, in the compartment of your vehicle that contains yourmodem or accessories. Before using your modem in a vehicle powered by liquefied petroleum gas (such aspropane or butane) ensure that the vehicle complies with the relevant fire and safety regulations of the country inwhich the vehicle is to be used.
Appendix A – Safety Precautions & Regulatory Standards complianceWireless ModemModule MTMMC-C Developer's Guide 22Safety StandardsTHIS WIRELESS MODEMMODULE COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS. Thiscellular modem meets the standards and recommendations for the protection of public exposure to RFelectromagnetic energy established by governmental bodies and other qualified organizations, such as thefollowing: · 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), § 2.1091and § 2.1093 as appropriate.The Multi-Tech ModemModule 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 MHzBand. Mult-Tech Systems, Inc. certifies that it has determined that the Modem complies with the RF hazardrequirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, SubpartE of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of theequipment in accordance with all instructions provided.The Modem is designed for and intends to be used in fixed and mobile applications. "Fixed" means that thedevice 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 such a way that aseparation distance of at least 20cm is normally maintained between the transmitter's antenna and the body ofthe user or nearby persons. The Modem is not designed for or intends to be used in portable applications (within20 cm of the body of the user) and such uses are strictly prohibited. To ensure that the unit complies with currentFCC regulations limiting both maximum RF output power and human exposure to radio frequency radiation, aseparation distance of at least 20cm must be maintained between the unit's antenna and the body of the userand any nearby persons at all times and in all applications and uses. Finally, the tune-up procedure for the O9EM2113 ensures that the maximum RF output power ofthe device does not exceed 30.0 dBm within the variations that can be expected due to quantity production andtesting on a statistical basis.Instructions to OEMsThe Multi-Tech product manual includes specific warnings and cautions in order to ensure that OEMs are awareof their responsibilities, with regards to RF exposure compliance, for products into which the modem isintegrated. With this guidance, the OEM will be able to incorporate into their documentation the necessaryoperating conditions and warnings. OEMs need to provide a manual with the ‘’final’’ product that clearly states the operating requirements andconditions and that these must be observed to ensure compliance with current FCC RF exposure requirements /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/or markings for their product.Regulatory Standards ComplianceCDMA complianceThe ModemModule is in compliance with reference regulations: TBR 19, TBR 20, TBR 31, TBR 32.CE LabelThe Wireless ModemModule is CE compliant, which implies that the modem is in conformity with the EuropeanCommunity directives and it bears the CE label.
