4. matters need attention
A．About the use of WIFI environment, wireless signal easily influenced by the surrounding environment is very big, such as
trees, such as metal barrier will have certain absorption of the wireless signal, which in practice, data transmission is
affected by a certain distance. B. Because the metal shell is shielded from the radio frequency signal, it is recommended
not to be installed in the metal enclosure. C. PCB cloth plate: because the metal will weaken the function of the antenna,
when giving the module cloth board, it is forbidden to spread the ground and the line under the module antenna, if it can
be hollowed out better.

FCC Statements
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15
B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to show compliance
with 15 while the module is installed and operating.
Furthermore the module should be transmitting and the evaluation should confirm that the module's
intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply
the appropriate equipment authorization (e.g. Verification) for the new host device per definition in §15.101.
Integrator is reminded to assure that these installation instructions will not be made available to the
end-user of the final host device.
The final host device, into which this RF Module is integrated" has to be labeled with an auxiliary label
stating the FCC ID of the RF Module, such as "Contains FCC ID: 2AG94-C-8068
This device is acting as slave and operating in the 2.4 GHz (2412 ~2462 MHz) band.
"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."
"Changes or modifications to this unit not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment."
the Integrator will be responsible to satisfy SAR/ RF Exposure requirements, when the module integrated
into the host device.
Module statement
The single-modular transmitter is a self-contained, physically delineated, component for which compliance
can be demonstrated independent of the host operating conditions, and which complies with all eight
requirements of § 15.212(a)(1) as summarized below.
1) The radio elements have the radio frequency circuitry shielded.
2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15
requirements with any type of input signal.
3) The module contains power supply regulation on the module.
4) The module contains a permanently attached antenna.
5) The module demonstrates compliance in a stand-alone configuration.
6) The module is labeled with its permanently affixed FCC ID label.
7) The module complies with all specific rules applicable to the transmitter, including all the conditions
provided in the integration instructions by the grantee.
8) The module complies with RF exposure requirements.
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
RF Exposure Warning Statements:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment shall be installed and operated with minimum distance 20cm between the radiator & body.
This equipment could not be co-located or operating in conjunction with any other antenna or transmitter
except in accordance with the FCC multi-transmitter product procedures.
