The M3090 radio modem should behandled like any other mobile radio station.
Therefore, you – the integrator – should read this information before integrating
the modem with your application.

• The radio modem mustnot be used with or close to any medical life support
equipment.
• Used in proximity to personal medical electronic devices, such as
pacemakers or hearing aids, the modem may present a hazard. Make sure
that use of the modem is permitted; as a rule, radio transmitters must be
switched off at hospitals, on aeroplanes etc.
• The modem has no built-in fuse. To protect the power supply cables and
fulfil fire safety requirements, a fuse should be mounted as close to the
terminals of the power supply as possible.
• Never use the modem at a gas station, refuelling point, blasting area or other
explosive environment.
• If the antenna is to be mounted outdoors, consider protection from lightning.

• Do not expose the radiomodem to environmental or electrical loads beyond
the limits specified in FKDSWHU³7HFKQLFDO'DWD´. Any such exposure may
damage the modem.
• Make sure to connect the antenna EHIRUH the system connector. Operating
the modem without an antenna may cause severe damage.
• Do not connect more than one modem to a single antenna. Radio frequency
energy from the transmitter of one modem may damage another unit.
• Do not connect to the modem any component or product that is not
compatible with the M3090 interface as specified in this manual. Ericsson
does not warrant any defects, non-conformities and/or deviations caused by
such a connection.
Mismatched external components, such as improperly made connections or
incorrectly designed or installed antennas, may cause radiation limits to be
exceeded, which could lead to malfunction in the modem or the host
equipment.
• Operating the modem close to other electronic devices, such as antennas,
television sets or radios, may cause electromagnetic interference.
• Do not place the modem close to magnetic storage media, such as credit
cards, computer diskettes etc.
• Do not try to dismantle the modem, or you may lose your warranty. The
modem does not have any user-serviceable components.

This manual describes the M3090 radio modem and defines what is required
from the host equipment and the environment in which the modem is to be
integrated.
The manual also provides technical data and background information about
antennas and the Mobitex system.
:KR6KRXOG5HDGWKLV0DQXDO"
This manual is intended for engineers in OEM companies who plan and
implement the integration of the M3090 radio modem with various host
equipment for operation in a Mobitex network.
It is assumed that the reader is familiar with the basics of radio and
telecommunications technology.
In addition to this manual, most integration engineers will require the following
to start up and test an integrated radio modem successfully:
• the MASC (Mobitex Asynchronous Communication Protocol) chapter in
the Mobitex Interface Specification (MIS).
• an M3090 Integrator’s Kit (from Ericsson).

To get an understanding of the basics of a Mobitex network and the function of
the M3090 radio modem, read FKDSWHU³,QWURGXFWLRQ´.
Readers who are not familiar with the basics of antenna selection and design
should also read FKDSWHU³$ERXW$QWHQQDV´.
The following two, FKDSWHU³7HFKQLFDO'DWD´ and FKDSWHU³+RVW

of the modem.
Information about type approval and type approval authorities, mainly inNorth
America, is presented in FKDSWHU³7\SH$SSURYDO´.
Finally, the ,QGH[ lists items in alphabetical order, with references to page
