Wireless Interoperability
The end product integrating this module is designed to be interoperable with any
wireless LAN product that is based on direct sequence spread spectrum (DSSS)
and orthogonal frequency division multiplexing (OFDM) radio technology and to
comply with the following standards.
･IEEE Std 802.11b Standard on 2.4GHz Wireless LAN

Safety
The end product integrating this module, like other radio devices, emits radio
frequency electromagnetic energy. The level of energy emitted by this device,
however, is less than the electromagnetic energy emitted by other wireless devices
such as mobile phones. The end product integrating this module operates within
the guidelines found in radio frequency safety standards and recommendations.
These standards and recommendations reflect the consensus of the scientific
community and result from deliberations of panels and committees of scientists
who continually review and interpret the extensive research literature. In some
situations or environments, the use of the end product integrating this module may
be restricted by the proprietor of the building or responsible representatives of the
applicable organization. Examples of such situations include the following:
･Using the end product integrating this module onboard airplanes, or
･Using the end product integrating this module in any other environment
where the risk of interference with other devices or services is perceived or
identified as being harmful.
If uncertain of the policy that applies to the use of wireless devices in a specific
organization or environment (an airplane, for example), ask for authorization to use
the end product integrated into this module before turning it on.

USA-Federal Communications Commission (FCC)
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy. If not installed and used in accordance with the instructions, it may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by tuning the equipment off and on, the user is
encouraged to try and correct the interference by one or more of the following
measures:
-Reorient or relocate the receiving antenna.
-Increase the distance between the equipment and the receiver.
-Connect the equipment to outlet on a circuit different from that to which the
receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Labeling
MITSUMI WiFi module DWM-W046 labelled as below.
FCC ID: EW4DWMW046
The proposed with FCC ID label format is to be placed on the module. If FCC ID is
not visible when the module is installed into the system, “Contains FCC ID:
EW4DWMW046” shall be placed on the outside of final host system.
Caution: Exposure to Radio Frequency Radiation.
To comply with FCC RF exposure compliance requirements, a separation distance
of at least 20 cm must be maintained between the antenna of this device and all
persons. This device must not be co-located or operating in conjunction with any

other antenna or transmitter.
Canada-Industry Canada (IC)
This device complies with RSS 210 of Industry Canada.
Operation is subject to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may cause
undesired operation of this device.
L ‘ utilization de ce dispositif est autorisée seulement aux conditions suivantes :
(1) il ne doit pas produire de brouillage et
(2) l’ utilisateur du dispositif doit étre prêt à accepter tout brouillage radioélectrique
reçu, même si ce brouillage est susceptible de compromettre le fomctionnement du
dispositif.
The term “IC” before the equipment certification number only signifies that the
Industry Canada technical specifications were met.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not
more than that required for successful communication.
To prevent radio interference to the licensed service, this device is intended to be
operated indoors and away from windows to provide maximum shielding.
Equipment (or its transmit antenna) that is installed outdoors is subject to licensing.
Pour empecher que cet appareil cause du brouillage au service faisant l’objet d’une
licence, il doit etre utilize a l’interieur et devrait etre place loin des fenetres afinde
Fournier un ecram de blindage maximal. Si le matriel (ou son antenne d’emission)
est installe a l’exterieur, il doit faire l’objet d’une licence.
Caution: Exposure to Radio Frequency Radiation.
To comply with IC RF exposure compliance requirements, a separation distance of
at least 20 cm must be maintained between the antenna of this device and all
persons. This device must not be co-located or operating in conjunction with any
other antenna or transmitter.
