General Description
WCRC503 Wireless Power Receiver Module is the receiver part of a wireless power transceiver
module pair. A transceiver module pair consists of a transmitter module and a receiver module,
carefully tuned to be highly resonant with each other in order to accomplish efficient wireless
power transfer. The transmitter module transmits “resonant power” from the surface area of its
antenna (coil) defined by X & Y = power area and to a Z= height which is the distance from the
antenna surface. The receiver module, when positioned within the space defined by X,Y and Z,
receives the resonant power and performs the necessary conversions to supply to a load which is
typically the battery to be charged.

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 inter fer ence
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 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: To assure continued compliance, any changes or modifications not
expressly approved by the party responsible for compliance could void the user's
authority to operate this equipment. (Example - use only shielded interface cables
when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may
be installed such that 0.5 cm may be maintained between the antenna and users.
The final end product must be labeled in visible area with the following: “Contains
FCC ID: W23-WCRC503”
”
End Product Manual Information
The user manual for end users must include the following infor mation in a prominent
location “IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 0.5 cm from all persons and must not be colocated
or operating in conjunction with any other antenna or transmitter.” 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.
IMPORTANT NOTE: In the event that these conditions can not be met (for example
certain laptop configurations or colocation with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the
final product. In these circumstances, the OEM integrator will be responsible for
reevaluating the end product (including the transmitter) and obtaini ng a separate FCC
authorization. This device is intended only for OEM integrators under the following
conditions: The antenna must be installed such that 0.5 cm is maintained between
the antenna and users. As long as a condition above is met, further transmitter test
will not be required. However, the OEM integrator is still responsible for testing
their end product for any additional compliance requirements required with
this module installed (for example, digital device emissions, PC peripheral
requirements, etc.).
