4.2.3 Modifications
The FCC requires the user to be notified that any changes or modifications made to this device that
are not expressly approved by u-blox could void the user's authority to operate the equipment.
⚠ Manufacturers of mobile or fixed devices incorporating the SARA-R4 series modules are
authorized to use the FCC Grants of the SARA-R4 series modules for their own final products
according to the conditions referenced in the certificates.
⚠ The FCC Label shall in the above case be visible from the outside, or the host device shall bear a
second label stating:
o For SARA-R410M modules: "Contains FCC ID: XPY2AGQN4NNN"
o For SARA-R412M modules: "Contains FCC ID: XPYUBX18ZO01"
o For SARA-R422, SARA-R422S, SARA-R422M8S: "Contains FCC ID: XPYUBX20VA01"
⚠ IMPORTANT: Manufacturers of portable applications incorporating the SARA-R4 series modules
are required to have their final product certified and apply for their own FCC Grant related to the
specific portable device. This is mandatory to meet the SAR requirements for portable devices.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
⚠ Additional Note: as per 47CFR15.105 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:
o Reorient or relocate the receiving antenna
o Increase the separation between the equipment and receiver
o Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected
o Consultant the dealer or an experienced radio/TV technician for help
