EnPointe EP-W01 User manual

The EP-W01 holds full modular approval. The OEM must
follow the regulatory guidelines and warnings listed below to
inherit the modular approval.
The EP-W01 modules are fencingspecific radio modules,
designed to interface with the EnPointe Fencingwireless
fencingscoringsystems. These modules are designed for
integration into scoringmachines, repeater lights and other
sport fencingproducts, and can be used to allow other sport
fencingmanufacturers to access the EnPointe Fencing
proprietary data communications via the custom radio
network.
These modules are not user programmable, as they are
issued from EnPointe Fencingfully programmed for the
user’s needs. The radio communication core uses the Nordic
nRF52833 SoC, with an ARM Cortex-M4F MCU, 512KB flash,
128KB RAM, embedded 2.4GHz multi-protocol transceiver,
and a u.FL connector for an external antenna.

EP-W01 User Manual
The EP-W01 holds full modular approval. The OEM must
follow the regulatory guidelines and warnings listed below to
inherit the modular approval.
ANTENNA INFORMATION
The module has been designed to operate with the antennas
listed below.
Note: the OEM is free to choose another vendor’s antenna of
like type and equal or lesser gain as an antenna appearingin
the table and still maintain compliance. Reference FCC Part
15.204(c)(4) for further information on this topic.
FEDERAL COMMUNICATIONS COMMISSION (FCC)
STATEMENT
You are cautioned that changes or modifications not
expressly approved by the part responsible for compliance
could void the user’s authority to operate the equipment.
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 turningthe
equipment oand on, the user is encouraged to try to
correct the interference by one or more of the following
measures:
— Reorient or relocate the receivingantenna
— Increase the separation between the equipment and
receiver.
— Connect the equipment into an outlet on a circuit dierent
from that to which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician
for help.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the followingtwo conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received,
includinginterference that may cause undesired operation
of the device.
FCC RF RADIATION EXPOSURE STATEMENT
This equipment complies with FCC radiation exposure limits
set forth for an uncontrolled environment. End users must
follow the specific operating instructions for satisfying RF
exposure compliance. This transmitter must not be co-
located or operating in conjunction with any other antenna or
transmitter. This device is intended only for OEM integrators
under the following conditions:
1. The module may not be co-located with any other
transmitter or antenna.
2. The module must be used with the firmware provided by
EnPointe FencingPty Ltd.

EP-W01 User Manual
If the conditions above are met, further transmitter testingis
not required. However, the OEM integrator is still
responsible for testingtheir end-product for any additional
compliance requirements required with this installed module.
The end product with this module may be subject to FCC
part 15 unintentional emissions test requirements.
Important note: If these conditions cannot be met (for
example, certain laptop configurations or co-location with
another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID cannot be used on the final
product. In these circumstances, the OEM integrator is
responsible for re-evaluatingthe end product (includingthe
transmitter) and obtaininga separate FCC authorization.
END PRODUCT LABELLING
Any device incorporatingthis module must include an
external, visible, permanent markingor label which states:
“Contains FCC ID: 2A3F8W01”.
MANUAL INFORMATION TO END USER
The OEM integrator must be aware not to provide
information to the end user regardinghow to install or
remove this RF module in the user’s manual of the end
product which integrates this module. The end user manual
shall include all required regulatory information/warningas
shown in this manual.
