4.3 Innovation, Science, Economic Development Canada notice
ISED Canada (formerly known as IC - Industry Canada) Certification Number: 8595A-UBX19KM01
4.3.1 Declaration of Conformity
This device complies with the ISED Canada license-exempt RSS standard(s). Operation is subject to
the following two conditions:
this device may not cause harmful interference
this device must accept any interference received, including interference that may cause
undesired operation
⚠ Radiofrequency radiation exposure information: this equipment complies with the radiation
exposure limits prescribed for an uncontrolled environment for fixed and mobile use conditions.
This equipment should be installed and operated with a minimum distance of 20 cm between the
radiator and the body of the user or nearby persons. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter except as authorized in the
certification of the product.
⚠ The gain of the system antenna(s) used for the SARA-R5 series modules (i.e. the combined
transmission line, connector, cable losses and radiating element gain) must not exceed the value
stated in the ISED Canada Grant for mobile and fixed or mobile operating configurations:
o 5.6 dBi in 700 MHz, i.e. LTE FDD-12 band
o 5.9 dBi in 750 MHz, i.e. LTE FDD-13 band
o 6.1 dBi in 850 MHz, i.e. LTE FDD-5 band
o 6.1 dBi in 850 MHz, i.e. LTE FDD-26 band
o 6.8 dBi in 1700 MHz, i.e. LTE FDD-4 band
o 8.5 dBi in 1900 MHz, i.e. LTE FDD-2 band
o 8.5 dBi in 1900 MHz, i.e. LTE FDD-25 band
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 SARA-R5 series modules are authorized to
use the ISED Canada Certificates of the SARA-R5 series modules for their own final host products
according to the conditions referenced in the certificates.
⚠ Manufacturers of mobile or fixed devices incorporating SARA-R5 series modules are authorized to
use the ISED Certificates of SARA-R5 series modules for their own final host products if, as per
FCC KDB 996369, the antenna trace design implemented on the host PCB is electrically equivalent
to the antenna trace design implemented on the u-blox host PCB used for the regulatory type
approvals of the SARA-R5 series modules, described in details in section 2.4.2.3.
⚠ In case of antenna trace design change, a Class IV Permissive Change application is required to be
filed by the grantee, or the host manufacturer can take responsibility through the ISED Multiple
Listing (new application) procedure followed by an ISED Class IV Permissive Change application.
⚠ If the ISED Certificates of the SARA-R5 series modules can be used for the final host product, as
the conditions above are met, the ISED Label of the module shall be visible from the outside, or the
host device shall bear a second label stating:
"Contains IC: 8595A-UBX19KM01"
