II. The trace Impedance of the antenna port (Pin 18) is 50 Ω. In order to minimize the return
loss, it is recommended to use short traces.
III. Keep enough clearance between the antenna port (Pin 18) and surrounding GND to
minimize the power loss.

Federal Communications Commission Statement
This device complies with FCC Rules Part 15. Operation is subject to the following two conditions:
•This device may not cause harmful interference.
•This device must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to
Part 15 of the Federal Communications Commission (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 causes 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 doing 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.
FCC Caution
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user‘s authority to operate the equipment.
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End
users must follow the specific operating instructions for satisfying RF exposure compliance. To maintain
compliance with FCC exposure compliance requirement, please follow operation instruction as documented
in this manual.
This equipment must be installed and operated in accordance with provided instructions and the
antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm
from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.
FCC Label Instructions:
The outside of final products that contains this module device must display a label
referring to the enclosed module. This exterior label can use wording such as: “Contains
Transmitter Module FCC ID:YAICM05”,or “Contains FCC ID: YAICM05”, Any similar wording that expresses
the same meaning may be used.
