BTA-QC3031-3M

Preliminary Datasheet

(Version 01)

Issued date: October 27, 2020

This device is intended only for OEM integrators under the following conditions:

The use of the printed antenna with gain=-0.46dBi(2.4GHz)

IMPORTANT NOTE:

In the event that these conditions can’t be met (for example certain laptop configurations or

co-location with another transmitter), then the FCC authorization is no longer considered

valid and FCC ID can’t 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

obtain a separate FCC authorization.

End Product Labeling

The final end product must be labeled in a visible area with the following:

“Contains FCC ID: 2AABGQ3031-3M”.The grantee’s FCC ID can be used only when all FCC

compliance requirements are met.
