7. Statement
FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247
Integral antenna with gain 1.5dBi
FCC Regulatory Compliance:
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.
Note: 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.
Warning: changes or modifications not expressly approved by the party responsible for compliance
could void the user’
If power exceeds the limit and the distance(Over 20cm distance in actual use between the device and user)
is compliance with the requirement
RF Exposure Compliance:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20cm between the radiator and
any part of your body.
Notice to OEM integrator
If the FCC ID 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.
The end product shall haves the words “Contains Transmitter Module FCC ID: 2AOKI-WFM603USB1”.
The device must be professionally installed.
The intended use is generally not for the general public. It is generally for industry/commercial use.
The connector is within the transmitter enclosure and can only be accessed by disassembly of the
tansmitter that is not normally required. The user has no access to the connector.
Installation must be controlled. Installation requires special training.
Any company of the host device which installs this modular with unlimited modular approval should perform
the test of radiated & conducted emission and spurious emission, etc. according to FCC part 15C: 15.247
and15.209 & 15.207, 15B Class B requirement, only if the tests result comply with FCC part 15C: 15.247
and 15.209 & 15.207, 15B Class B requirement, then the host can be sole legally.
