5.4 FCC Warning
Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
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.
To satisfy FCC RF Exposure requirements for this transmission devices, a separation distance of 20cm or
more should be maintained between the antenna of this device and persons during operation. To ensure
compliance, operation at closer than this distance is not recommended. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The
modular transmitter must be equipped with either a permanently affixed label or must be capable of
electronically displaying its FCC identification number：
(A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC
identification number, and, if the FCC identification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also display
a label referring to the enclosed module. This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID:N8NLSD4WF0459.” Any similar wording that expresses the same
meaning may be used. The Grantee may either provide such a label, an example of which must be
included in the application for equipment authorization, or, must provide adequate instructions along with
the module which explain this requirement. In the latter case, a copy of these instructions must be
included in the application for equipment authorization.
