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.
