[Appendix2] FCC Certification Requirements
1. Caution
Any changed or modifications not expressly approved by the party responsible for compliance could
void the user`s authority to operate this equipment.
2. OEM installation guide
I. OEM integrators must be instructed to ensure that the end-user has no manual instructions to
remove or install the module.
II. This module is to be installed only in mobile of fixed devices. ▪ Mobile device: The devices is
to be generally used in such a way that a separation distance of at least 20cm is normally
maintained between the transmitter`s radiating structures and the body of the user or nearby
persons. ▪ Fixed devices: The device is physically secured at one location and is not able to
be easily moved to another location.
III. To ensure compliance with all non-transmitter functions the host manufacturer is responsible
for ensuring compliance with the module(s) installed and fully operational.
IV. To satisfy FCC exterior labeling requirements, the following text must be placed on exterior of
the end product.
V. An additional permanent label referring to the enclosed module: “Contains Transmitter
Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1” must be used. The host
OEM user manual must also contain clear instructions on how end users can find and/or
access the module and the FCC ID.
3. FCC RF exposure requirements
The antenna used with this module must be installed to provide a separation distance of at least
20cm from all persons, and must not transmit simultaneously with any other antenna or transmitter
except in accordance with FCC multi-transmitter product procedures.
4. FCC authorization for this module
If this module is installed in portable devices or the different antenna configurations are used, the
FCC authorizations are no longer considered valid and FCCID for module cannot be used on the final
product. And the OEM installer will be responsible for re-evaluating the final product including this
module and obtaining separate FCC authorization.
5. Information for importation of radio frequency devices in to the United States
To ensure compliance with all non-transmitter functions the host manufacturer is responsible 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. Please see CFR47 Part 2 Subpart J Equipment
Authorization Procedures, KDB784748 D01 v07, and KDB 997198.
6. User Information
This device complies with Part 15 of the FCC`s Rule. Operation is subject to the following to
conditions;
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause
undesirable operation.
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.
