U.S. FCC Part 15 Regulatory Information
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.
Any 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.
This modular complies with FCC RF radiation exposure limits set for an
uncontrolled environment. This transmitter must not be co-located or operating
in conjunction with any other antenna or transmitter. This modular must be
installed and operated with a minimum distance of 20 cm between the radiator
and the user’s body.
The device shall automatically discontinue transmission in cases of absence of
information to transmit, or operational failure. Then it will scan the
available radio signals. If this signal is connected before, it will be
automatically connected, otherwise manual connections will be necessary.
The devices must be installed and used in strict accordance with the
manufacturer’s instructions as described in the user documentation that comes
with the product.
The module must be installed in Host. 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 re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
This device complies with FCC part 15C: 15.247 and 15.407.
This device and its antenna(s) must not be co-located or operating in
conjunction with any other antenna or transmitter. The module should be
installed at a minimum distance of 20 cm away from a person nearby. The host
product manufacturer should state this information to the host instruction
manual.
Trace antenna designs – not applicable.
Any final host product with the modular transmitter installed should be under
test according to guidance given in KDB 996369 D04. To enter test mode for
module, secure CRT command is necessary. When something wrong happens in
configuring test modes for host product with module, host product manufacturer
should coordinate with module manufacturer for technical support. It is
recommended that some investigative measurements should be taken to confirm
that host product with module installed does not exceed the spurious emissions
limits or band edge limits.
The modular complies with FCC authorised for the specific rule parts (FCC Part
15.247 and 15.407) list on the grant, and that the host product manufacturer
is responsible for compliance to any other FCC rules that apply to the host
not covered by the modular transmitter grant of certification. The final host
product still requires Part 15 subpart B compliance testing with the modular
transmitter installed when contains digital circuity.
The device is going to be operated in 5150~5350MHz frequency range. It is
restricted indoor environment only.
The end product must carry a label stating “Contains FCC ID: SVNM8822CU1” or
shall use e- labeling.
