These connections are respectively the pin 3 and 4 for the +5V and the pins 1 and 2 for the ground (GND). The power supply is 5V +/-5% 1A. 3.2.2 Serial Link RS232 This interface is needed for communication with a remote terminal with respect to the RS232 V.28 standard levels. As the integrated modem does not include a transceiver MAX3238 or MAX3237, this one has to be added outside with a SUBD9. The connection between the WMOi3 and the transceiver must not exceed 10 cm.

They already include the convenient biasing for an electret microphone (0,5 mA and 2 Volts). This electret microphone can be directly connected on these inputs. The impedance of the microphone 2 has to be around 2kΩ. These inputs are the standard ones for an handset design while MIC1 inputs can be connected to an external headset or a handsfree kit. The gain of MIC2 inputs is internally adjusted. The gain can be tuned from 30dB to 51dB. The connexion to the microphone is direct.

To use these inputs with an electret microphone, bias has to be generated outside the WMOI3 modem according to the characteristic of this electret microphone. These inputs are the standard ones used for an external headset or a handsfree kit. The connection can be either differential or single-ended but using a differential connection in order to reject common mode noise and TDMA noise is recommended. When using a single-ended connection, be sure to have a very good ground plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path. The gain of MIC1 inputs is internally adjusted. The gain can be tuned from 30dB to 51dB.

WMOi3 integrated Modem 5 Safety Precautions It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully. 5.1 Safety in explosive substance environments • • WMOI3 is not recommended to be used in a gas station. In fuel depots, chemical plants and locations where explosives are ignited , users are reminded to comply with restrictions regarding the use of radio devices. 5.2 Aircraft safety The use of WMOI3 on board aircraft is forbidden by law. Consequently, Switch OFF your modem when in an aircraft, disrupt the cellular network is illegal. Failure to observe this instruction may lead to suspension or denial of cellular telephone services to the offender, or legal action or both. 5.3 Safety in medical equipment environments Switch OFF your WMOI3 when in hospital. There may be a hazard associated with the operation of your modem close to inadequately protected personal medical devices such as hearing aids and pacemakers. Please address all questions to the medical devices manufacturer to determine if it is adequately protected. 5.4 Vehicle safety • • • • Do not use your WMOI3 modem while driving, unless equipped with a correctly installed vehicle hands-free kit. Comply with national regulations on the use of cellular telephones in vehicles. If incorrectly installed in a vehicle, the WMOI3 modem could interfere with the correct functioning of vehicle electronics. To avoid such problems, ensure that the installation has been performed by a skilled personnel. Safety on the road requires that it is not permitted to signal incoming calls by sounding the vehicle’s horn or flashing the lights. 13 confidential © This document is the sole and exclusive property of WAVECOM.

RF exposure instructions Pursuant to 47 CFR 5 24.52 of the FCC Rules and Regulations, personal communications services (PCS) equipment is subject to the radiofrequency radiation exposure requirements specified in § 1.1307(b), $j 2.1091 and 5 2.1093, as appropriate. The Wavecom WM02-G1900 Modem is a GSM (PCS-1900) terminal which operates in the US licensed PCS frequency spectrum. The device transmits over the 1850-1910 MHz band and receives over the 1930-1990 MHz band. Wavecom, Inc. certifies that it has determined that the Modem complies with the RF hazard requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart E of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of the equipment in accordance with all instructions provided. The Modem is designed for and intended to be used in mobile, not fixed applications. “Fixed” means that the 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 such a way that a separation distance of at least 20 cm (8 inches) is normally maintained between the transmitters antenna and the body of the user or nearby persons. The Modem is not designed for or intended to be used 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 power and human exposure to radiofrequency radiation, a separation distance of at least 20 cm must be maintained between the units antenna and the body of the user and any nearby persons at all times and in all applications and uses. Additionally, in mobile applications, maximum antenna gain must not exceed 3 dBi (to comply with Section 24.232(b)) and is limited to 7dBi 73dB for fixed applications. Finally, the tune-up procedure for the O9EWMOI3A ensures that the maximum RF output power of the device does not exceed 30.0dBm within the variations that can be expected due to quantity production and testing on a statistical basis.

Instructions to OEM Wavecom User’s manual includes specific warnings and cautions in order to ensure that OEMs are aware of their responsibilities, with regard 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 (refer to chapter 6. RF exposure instructions). 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. 16 This document is strictly confidential and shall not be copied without written authorisation of Wavecom
