Regulatory Information
Operational Information
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
･IEEE Std 802.11g 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.
Labelling
MITSUMI WiFi module DWM-W004 labelled as below.
The proposed 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:EW4DMW004” 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.
The installer of this radio equipment must ensure that the antenna is located or pointed
such that it does not emit RF field in excess of Health Canada limits for the general
population; consult Safety Code 6, obtainable from Health Canada’s website at
www.hc-sc.gc.ca/rpb.
