Compliance with FCC requirement 15.407(c)
Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog
baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband
portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only
while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinue transmission in
case of either absence of information to transmit or operational failure.

Manual and Product Labeling information To The End User
The end user manual shall include all required regulatory information/warning as show in this manual.And when this module is
installed in the host product, you must include a “Contain FCC ID : N6C-PMACS”and a “Contain IC: 4908A-PMACS” in the label of
the host product.
This module is designed for embedded purpose into the general electric devices, and is not designed for high reliability demands
like aircraft instruments, nuclear control instruments, high reliability medical instruments, high reliability security instruments or
any other devices required extremely high reliability and quality.
• As this module communicates by radio wave, it is strongly recommended to use some security system to prevent unexpected
information leakage to others.
• This module is a radio module for embedded purpose. Please understand functions and features of this module, and evaluate as
the final product which has this module embedded. Also, as evaluation of EMC conformity of this module has not been performed,
EMC conformity evaluation and application must be performed with the final product which this module is embedded.
• This module will effect to some other device or be affected by the some other device using the same frequency band.Please
investigate the environment to use this module beforehand.
• Disassembling or modifying the radio module leads to punishment based on radio law.
• This module is the embedded module that has the exposed connectors or some devices.Please be careful for electro static,
condensing, and other dusts.
• “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.”
IMPORTANT NOTE: In the event that these conditions cannot be met (for example co-location with another transmitter), then the
FCC / IC authorization is no longer considered valid and the FCC / IC ID cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for reevaluating the end product (including the transmitter) and obtaining a
separate FCC / IC authorization. As long as a condition above is 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 (for example, digital device emissions, PC peripheral requirements, etc.
