EU Regulatory Conformance
Hereby, Pycom Ltd declares that this device is in compliance
with the essential requirements and other relevant provisions of
Directive 1999/5/EC.
Federal Communication Commission Interference
Statement
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.
(2) This device must accept any interference received, including
interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to
operate the equipment.
NOTE: 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.
for ensuring compliance with the module(s) installed and fully
operational. For example, if a host was previously authorized as
an unintentional radiator under the Declaration of Conformity
procedure without a transmitter certified module and a module is
added, the host manufacturer is responsible for ensuring that the
after the module is installed and operational the host continues to
be compliant with the Part 15B unintentional radiator requirements
The module is limited to OEM installation ONLY. The module is
limited to installation in mobile or fixed application. We hereby
acknowledge our responsibility to provide guidance to the host
manufacturer in the event that they require assistance for ensuring
compliance with the Part 15 Subpart B requirements.
IMPORTANT NOTE:
In the event that 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 will
be responsible for reevaluating the end product(including the
transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the
antenna may be installed such that 20 cm 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: 2AJMTLOPY4R”.
The grantee's FCC ID can be used only when all FCC compliance
requirements are met.
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.
RF Warning Statement
To comply with FCC RF exposure compliance requirements, the
antennas 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.
This device is intended only for OEM integrators under the
following conditions:
1) The antenna must be installed such that 20 cm is maintained
between the antenna and users, and
2) The transmitter module may not be co-located with any other
transmitter or antenna.
As long as two conditions above are 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. To ensure compliance with all
non-transmitter functions the host manufacturer is responsible
Manual Information to the End User
The OEM integrator has to be aware not to provide information to
the end user regarding how to install or remove this RF module in
the user’s manual of the end product which integrates this module.
In the user manual of the end product, the end user has to be
informed that the equipment complies with FCC radio-frequency
exposure guidelines set forth for an uncontrolled environment.
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.
The end user manual shall include all required regulatory
information/warning as show in this manual.
The maximum operating ambient temperature of the equipment
declared by the manufacturer is
-20~+85C
