WIRELESS LAN + BLUETOOTH MODULE
MODEL DWM-W314K
The purpose of this manual is to explain correct way how to integrate module DWM-W314K to
the end product. 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 wireless LAN + Bluetooth module, model DWM-W314K 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 and
Bluetooth product that is based on direct sequence spread spectrum (DSSS) ,orthogonal frequency
division multiplexing (OFDM) ,Frequency Hopping Spread Spectrum (FHSS) and 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
･Bluetooth V4.0 Standard
Federal Communications Commission (FCC) Statement
15.105(b) This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the 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 and, if not installed and used in accordance with the
instructions, 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 turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help.
15.21: You are cautioned that changes or modifications not expressly approved by the part
responsible for compliance could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
1.This Transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Except the following combination DWM-W314K and K1506M.
2. The available scientific evidence does not show that any health problems are associated with using low
power wireless devices. There is no proof, however, that these low power wireless devices are absolutely
safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range
while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of
low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of
low-level RF exposures have not found any biological effects. Some studies have suggested that some
biological effects might occur, but such findings have not been confirmed by additional research.
DWM-W314K has been tested and found to comply with FCC radiation exposure limits set forth for an
uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines.
FCC RF Exposure requirements:
This device and its antenna(s) must not be co-located or operation in conjunction with any other
antenna or transmitter.
Except the following combination DWM-W314K and K1506M.
15.19
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 of the device.
Labeling:
Wireless LAN + Bluetooth module DWM-W314K labeled as below.
FCC ID: EW4DWMW314K
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:
EW4DWMW314K” shall be placed on the outside of final host system
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
guideline.
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: PCB printed antenna
Antenna Gain: -4.7dBi
If an antenna with higher gain or new antenna type is used with this module, integrators must
contact to manufacture 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.
Notice.
Since this module is not sold to general end users directly, there is no user manual of module.
For the details about this module, please refer to the specification sheet of module.(Next Page)
This module should be installed in the host device according to the interface specification
(installation procedure).
This module built-in use in equipment.
If you do not include the module to the equipment,only be operated by “TX continue” and
“RX continue” stand alone mode separated.
