This module is intended for OEM integrator. The OEM integrator is responsible for the compliance 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.

FCC Caution:

Any Changes or modifications not expressly approved by the party responsible for compliance could

void the user's authority to operate the 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.

Host product manufacturers that they need to provide a physical or e-label stating, “Contains FCC

ID:2ALPH-E22900M22S” 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.

The final host manual shall include the following regulatory statement:This equipment has been tested and

found to comply with the limits for a 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 RF Radiation Exposure Statement:

1. This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
2. This equipment complies with RF radiation exposure limits set forth for an uncontrolled
environment.

3.This equipment should be installed and operated with minimum distance 20cm between the radiator&

your body.
