Federal Communication Commission Interference Statement
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 gu ara ntee that interference will n ot occur in a parti cular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment of f
and on, the user is encouraged to try to correct the interference by one 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 Caution: Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this 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.
This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or
transmitter.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance requirement of the
end product, which integrates this module.
20cm minimum distance has to be able to be maintained between the antenna and the users for the host this module is
integrated into. Under such configuration, the FCC radiation exposure limits set forth for a/an populatio n/uncontrolled
environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this
equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the antenna
while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency exposure
guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any changes or
modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment. If the size
of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be available in the users
manual: This device complies with Part 15 of 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.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains TX FCC ID: B94RSVLD0707 " and
“Contains TX IC: 466F-RSVLD707”. If the size of the end product is larger than 8x10cm, then the following FCC
part
15.19 statement has to also be available on the label: This device complies with Part 15 of 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.
