SARA-R4 series - System integration manual
UBX-16029218 - R20 Approvals Page 112 of 129
C1-Public
The SARA-R4 series modules include the capability to configure the device by selecting the operating
mobile network operator profile, radio access technology, and bands. In the SARA-R4 series AT
commands manual [2], see the +UMNOPROF, +URAT, and +UBANDMASK AT commands.
As these configuration decisions are made, u-blox reminds manufacturers of the end-device
integrating the SARA-R4 series modules to take care of compliance with all the certification approvals
requirements applicable to the specific integrating device to be deployed in the market.
☞ It is strongly recommended to configure the module to the applicable MNO profile, RAT, and LTE
bands intended for the application device and within regulatory compliance. The SARA-R4 series
modules are not intended be used in the factory-programmed setting.
☞ The certification of the application device that integrates a SARA-R4 series module and the
compliance of the application device with all the applicable certification schemes, directives and
standards are the sole responsibility of the application device manufacturer.
SARA-R4 series modules are certified according to all capabilities and options stated in the Protocol
Implementation Conformance Statement document (PICS) of the module. The PICS, according to the
3GPP TS 51.010-2 [13], 3GPP TS 36.521-2 [15] and 3GPP TS 36.523-2 [16], is a statement of the
implemented and supported capabilities and options of a device.
☞ The PICS document of the application device integrating SARA-R4 series modules must be
updated from the module PICS statement if any feature stated as supported by the module in its
PICS document is not implemented or disabled in the application device. For more details
regarding the AT commands settings that affect the PICS, see the SARA-R4 series AT commands
manual [2].
☞ Check the specific settings required for mobile network operators approvals as they may differ
from the AT commands settings defined in the module as integrated in the application device.

4.2.1 Safety warnings review the structure
• Equipment for building-in. Requirements for fire enclosure must be evaluated in the end product
• The clearance and creepage current distances required by the end product must be withheld when
the module is installed
• The cooling of the end product shall not negatively be influenced by the installation of the module
• Excessive sound pressure from earphones and headphones can cause hearing loss
• No natural rubbers, hygroscopic materials, or materials containing asbestos are employed
