FCC Statement:
The final end product must be labeled in a visible area with the following "Contains TX FCC
ID:2AATL-FNCC2541". If the size of the end product is smaller than 8x10cm, then additional
FCC part 15.19 stayement is required to be availale in the users manual:
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 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.
Caution: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
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 OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed.
This device is intended only for OEM integrators under the following conditions:
1)This module is granted as a Single Modular Approval.
2)This device has been designed to operate with a FPC antenna having a maximum gain of 0dBi.Only
this type of antenna may be used.
