FCC STATEMENT
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.
Note: 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.
Please notice that 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 FCC ID:2AHMR-ESP01M” or “Contains FCC
ID:2AHMR-ESP07S”or “Contains FCC ID:2AHMR-ESP12S” or “Contains FCC
ID:2AHMR-ESP12F” or “Contains FCC ID:2AHMR-ESP01E”or “Contains FCC
ID:2AHMR-ESP01F”any similar wording that expresses the same meaning may be used.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20cm
between the radiator & your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
The module is limited to OEM installation ONLY.
The OEM integrator is responsible for ensuring that the end-user has no manual instruction t
o remove or install module.
The module is limited to installation in mobile application.
A separate approval is required for all other operating configurations, including portable con
figurations with respect to Part 2.1093 and difference antenna configurations.
There is requirement that the grantee provide guidance to the host manufacturer for complia
nce with Part 15B requirements.
