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.
Frequency Tolerance: ± 20ppm

5. Antenna
Please refer to KDB 996369
•
•
Please perform the antenna design that followed the specifications of the
antenna.
•
About the signal line between an antenna and a module
It is a 50-ohm line design.
•
Fine tuning of return loss etc. can be performed using a matching network.
•
However, it is required to check "Class1 change" and "Class2 change" which the
authorities define then.
•
The concrete contents of a check are the following three points.
It is the same type as the antenna type of antenna specifications.
1.
An antenna gain is lower than a gain given in antenna specifications.
2.
The emission level is not getting worse.

6. Notice
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.
3)The use of an antenna with gain less than 1.2 dBi (2.4GHz).
As long as the 3 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.
End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such
that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area
with the following:
“Contains FCC ID:QGH-LB1GC”.
“Contains IC: 2473A-LB1GC”.
The grantee's FCC ID can be used only when all FCC compliance requirements are met.
Manual Information To the End User 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.
