To use theseinputs with an electret microphone, bias has to be generated outside theWMOI3 modem according to the characteristic of this electret microphone.These inputs are the standard ones used for an external headset or a handsfreekit. The connection can be either differential or single-ended but using adifferential connection in order to reject common mode noise and TDMA noiseis recommended. When using a single-ended connection, be sure to have avery good ground plane, a very good filtering as well as shielding in order toavoid any disturbance on the audio path.The gain of MIC1 inputs is internally adjusted. The gain can be tuned from30dB to 51dB.

Please follow the safety advice given below carefully.5.15.15.15.1 Safety in explosive substance environments Safety in explosive substance environments Safety in explosive substance environments 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 areignited , users are reminded to comply with restrictions regarding theuse of radio devices.5.25.25.25.2 Aircraft safety Aircraft safety Aircraft safety Aircraft safetyThe use of WMOI3 on board aircraft is forbidden by law. Consequently, SwitchOFF OFF OFF 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 cellulartelephone services to the offender, or legal action or both.5.35.35.35.3 Safety in medical equipment environmentsSafety in medical equipment environmentsSafety in medical equipment environmentsSafety in medical equipment environments Switch OFFOFFOFFOFF your WMOI3 when in hospital. There may be a hazard associatedwith the operation of your modem close to inadequately protected personalmedical devices such as hearing aids and pacemakers. Please address allquestions to the medical devices manufacturer to determine if it is adequatelyprotected.5.45.45.45.4 Vehicle safety Vehicle safety Vehicle safety Vehicle safety• Do not use your WMOI3 modem while driving, unless equipped with acorrectly installed vehicle hands-free kit.• Comply with national regulations on the use of cellular telephones invehicles.• If incorrectly installed in a vehicle, the WMOI3 modem could interferewith the correct functioning of vehicle electronics. To avoid suchproblems, ensure that the installation has been performed by a skilledpersonnel.• Safety on the road requires that it is not permitted to signal incomingcalls by sounding the vehicle’s horn or flashing the lights.
