compliance could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
- This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
- This equipment complies with RF 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.
Host product manufacturers that they need to provide a physical or e-label
stating, “Contains FCC ID:2A7MD-FM812 with their finished product.
Only those antennas with same type and lesser gain filed under this FCC ID can
be used with this device.
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.
The final host integrator must ensure there is no instruction provided in the
user manual or customer documentation indicating how to install or remove the
transmitter module except such device has implemented two-ways authentication
between module and the host system. 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.
This module has been tested and found to comply with part 15.247 requirements
for Modul ar Approval. This module is intended for OEM integrator. The OEM
integrator is responsible for the compli ance to all the rules that apply to
the product into which this certified RF module is integrated. Additional
testing and certification may be necessary when multiple modules are used.
