4.3.2 Modifications
ISED Canada 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 ISED Canada Certificates of the SARA-R4 series modules for their own final
products according to the conditions referenced in the certificates.
⚠ The ISED Canada 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 cellular modules: "Contains IC: 8595A-2AGQN4NNN"
o For SARA-R412M cellular modules: "Contains IC: 8595A-UBX18ZO01"
o For SARA-R422, SARA-R422S, SARA-R422M8S: "Contains IC: 8595A-UBX20VA01"
⚠ Innovation, Science and Economic Development Canada (ISED) Notices
This Class B digital apparatus complies with Canadian CAN ICES-3(B) / NMB-3(B).
Operation is subject to the following two conditions:
o this device may not cause interference
o this device must accept any interference, including interference that may cause undesired
operation of the device
Radio Frequency (RF) Exposure Information
The radiated output power of the u-blox Cellular Module is below the Innovation, Science and
Economic Development Canada (ISED) radio frequency exposure limits. The u-blox Cellular Module
should be used in a manner such that the potential for human contact during normal operation is
minimized.
This device has been evaluated and shown compliant with the IC RF Exposure limits under mobile
exposure conditions (antennas are greater than 20 cm from a person's body).
This device has been certified for use in Canada. Status of the listing in the Industry Canada’s REL
(Radio Equipment List) can be found at the following web address:
http://www.ic.gc.ca/app/sitt/reltel/srch/nwRdSrch.do?lang=eng
Additional Canadian information on RF exposure also can be found at the following web address:

⚠ IMPORTANT: Manufacturers of portable applications incorporating the SARA-R4 series modules
are required to have their final product certified and apply for their own Industry Canada
Certificate 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.
