FCC WARNING STATEMENT
Class B:
FEDERAL COMMUNICATIONS 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
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 grantee of this device
could void the user's authority to operate the equipment.
Labeling requirements
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.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may
be installed such that 20cm may be maintained between the antenna and users. The
final end product must be labeled in a visible area with the following: "Contains FCC
ID: MDZLTRT5370-WL ”

AmTRAN
WN4608R Specification Page 12/12 2011/12/12
RF exposure warning
This equipment must be installed and operated in accordance with provided
instructions and the antenna(s) used for this transmitter must be installed to
provide a separation distance of at least 20 cm from all persons and must not
be co-located or operating in conjunction with any other antenna or transmitter.
End-users and installers must be provide with antenna installation instructions
and transmitter operating conditions for satisfying RF exposure compliance.
FCC NOTICE: To comply with FCC part 15 rules in the United States, the system
must be professionally installed to ensure compliance with the Part 15 certification. It
is the responsibility of the operator and professional installer to ensure that only
certified systems are deployed in the United States. The use of the system in any
other combination (such as co-located antennas transmitting the same information) is
expressly forbidden.
Only the antennas listed below are allowed to be used with the EUT output power.
