include a transceiver MAX3238 or MAX3237, this one has to be added outside
with a SUBD9. The co nnection between t he WMOi3 and the tr ansceiver must
not exceed 10 cm. The table below lists the needed signals for this interface :

3.2.4.2 Microphone 1
The MIC1 inputs are differential and do not include internal bias. 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 co nnection in order to reje ct common mod e noise and TDM A 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.

6. 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 §
as appropriate.
1.1307(b), $j
2.1091 and 5 2.1093,
The Wavecom
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
fixed applications. Finally, the tune-up procedure for the
that the maximum RF output power of the device does not exceed
within the variations that can be expected due to quantity production and testing on
a statistical basis.

Instructions to
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
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.
