Regulatory Compliance
FCC Compliance
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.
Any Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in
any portable device, for example, USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The
maximum allowable antenna gain is 10dBi. This modular must be installed and operated with a minimum
distance of 20 cm between the radiator and user body. The allowed antenna type is external antenna.
If the FCC identification number is not visible when the module is installed inside another device, then the
outside of the device into which the module is installed must also display a label referring to the enclosed
module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID:
2AG32EM2148M .
When the module is installed inside another device, the user manual of this device must contain below
warning statements;
1. 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.
12
(2) This device must accept any interference received, including interference that may cause
undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as
described in the user documentation that comes with the product.
3. List of applicable FCC rules
This module has been tested and found to comply with part 25 requirements for Modular Approval.
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules)
listed on the grant, and that 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. If the
grantee markets their product as being Part 15 Subpart B compliant (when it also contains
unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host
product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
