Manufacturing Process
This section describes board-level characterization process parameters. During board’s
reflow process, the temperature seen by the package must be controlled. The
recommended peak temperature during production assembly is 245°C. This is comfortably
above the solder melting point (217°C).
SMT process verification
Recommends verification of the SMT process prior to high-volume board assembly,
including:
- Electrical continuity
- Visual and x-ray inspection after soldering to confirm adequate alignment, solder voids,
solder-ball shape, and solder bridging.
- Cross-section inspection of solder joints to confirm registration, fillet shape, and print
volume.

Federal Communication Commission Interference Statement
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 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 this 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.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna
or transmitter.

Professional installation instruction
Please be advised that due to the unique function supplied by this product, the device is
intended for use with our interactive entertainment software and licensed third-party only.
The product will be distributed through controlled distribution channel and installed by
trained professional and will not be sold directly to the general public through retail store.
1. Installation personal
This product is designed for specific application and needs to be installed by a
qualified personal who has RF and related rule knowledge. The general user shall
not attempt to install or change the setting.
2. Installation location
The product shall be installed at a location where the radiating antenna can be kept
20cm from nearby person in normal operation condition to meet regulatory RF
exposure requirement.
3. External antenna
Use only the antennas which have been approved by the applicant. The
non-approved antenna(s) may produce unwanted spurious or excessive RF
transmitting power which may lead to the violation of FCC/IC limit and is prohibited.
4. Installation procedure
Please refer to user’s manual for the detail.
5. Warning
Please carefully select the installation position and make sure that the final output
power does not exceed the limit set force in relevant rules. The violation of the rule
could lead to serious federal penalty.

Integration instructions for host product manufacturers
Applicable FCC rules to module
FCC Part 27
Summarize the specific operational use conditions
The module is professional installed equipment and must be installed in mobile device.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna
and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna
As long as 2 conditions above are met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed.
IMPORTANT NOTE: In the event that these conditions can not be met (for example
certain laptop configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating
the end product (including the transmitter) and obtaining a separate FCC authorization.
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module in the user’s manual of the end product which
integrates this module.
The end user manual shall include all required regulatory information/warning as show in
this manual.
Limited module procedures
The modular is professional installed equipment and must follow procedure of user manual
to install and setup the module. Permissive change is required for SAR evaluation if the
module is installed in portable device.
Trace antenna designs
Refer to trace antenna design document.
RF exposure considerations
20 cm separation distance and co-located issue shall be met as mentioned in “Summarize
the specific operational use conditions”.
Product manufacturer shall provide below text in end-product manual
“This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body.

Antennas
Dipole antenna with 1.23 dBi gain, SMA connector
Label and Compliance Information
Product manufacturers need to provide a physical or e-label stating
“Contains FCC ID: MXFGCM7243IDS-APB” with finished product.
Information on Test Modes and Additional Testing Requirements
Simulator is required to link up and set the module to transmit at specific frequency, output
power level under operation mode.
Additional Testing, Part 15 Subpart B Disclaimer
The module is only FCC authorized for the specific rule parts listed on the grant, and that
the host product manufacturer is responsible for compliance to any other FCC rules that
apply to the host not covered by the modular transmitter grant of certification. The final
host product still requires Part 15 Subpart B compliance testing with the modular
transmitter installed.
