It includes procedures that shall assist you to avoid unforeseen problems. This manual presents information that shows how module and OEM product, where module integrated, complies with regulations in certain regions. Any modifications, not expressly approved by the manufacturer could void the authority to operate in these regions. The MITSUMI WiFi Module, model DWM-W078 has to be installed and used in accordance with the technical description/installation instructions provided by the manufacturer. For detail information concerning type approval of this module(e.g. where this module is already pre-approved) please contact the authorized local distributor or the manufacturer. The system may only be implemented in the configuration that was authorized. Note that any changes or modifications to this equipment not expressly approved by the manufacturer could void the user’s authority to operate this equipment.
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 IEEE Std 802.11n Standard on 2.4GHz Wireless LAN Safety The end product integration 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 integration 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 15of 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 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. CAUTION: 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-W078 labeled as below. FCC ID: EW4DWMW078 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: EW4DWMW078” 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.
Instructions to OEM integrators A User manual provided to the end user must indicate the operating requirements and conditions that must be observed to ensure compliance with the above-mentioned FCC RF Exposure guidline. If this module is intended for use in a portable device, integrators are responsible for separate evaluation and/or approval to satisfy FCC RF Exposure requirements. The antenna used this module is as follows; Antenna type: Chip antenna Antenna gain: -9.2dBi If an antenna with higher gain or new antenna type is used with this module, Integrators must contact Mitsumi for additional testing and submission to the FCC. If other radio devices are to be integrated with this module, an additional evaluation and FCC submission may be required. Integrators are responsible for such additional evaluation and FCC submission.
