3. Operational Description
This Module able to transmit and receive messages using the SIGFOX network.
This module addresses the RCZ4 zone (Australia, New Zealand).
- Features
> Sigfox up-link and down-link functionality controlled by AT commands
> Temperature sensor
> Ultra-low power consumption
> High performance narrow-band Sigfox
- Time base of the RF frequency
For Sigfox RF frequency, a TCXO(48MHz) is a clock reference.
- Transmission
The Tx path produces a DBPSK-modulated signal. modulate RF signal generated by the synthesizer. The
modulated RF signal is fed to the integrated RX/TX switch and antenna interface and then out of the AX-
SFEU-1-01.
- Receiver
The Rx path is able to receive 922.3MHz signal and the noise amplifier is built in the inside of the chip, it
amplifies the received signal by the low noise amplifier according to the receiving intensity, and the
amplified signal is converted into the digital signal through the ADC, Packets will be interpreted.

5. Notice
<Warning Statements>
FCC Part 15.19 Statements:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
RF Exposure Statement
The antenna(s) must be installed such that a minimum separation distance of at least 20 cm
is maintained between the radiator (antenna) and all persons at all times. This device must
not be co-located or operating in conjunction with any other antenna or transmitter.
End Product Labeling
The module is labeled with its own FCC ID. If the FCC ID is not visible when the module is
installed inside another device, then the outside of the device into which the module is
installed must also display a label referring to the enclosed module. In that case, the final
end product must be labeled in a visible area with the following:
“Contains FCC ID: 2ABA2SFM10R4
" Contains IC: 11534A-SFM10R4
OEM Responsibilities to comply with FCC Regulations
The module has been certified for integration into products only by OEM integrators under
the following condition:
- The antenna(s) must be installed such that a minimum separation distance of at least 20
cm is maintained between the radiator (antenna) and all persons at all times.
- The transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
As long as the two condition above is met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed (for example, digital
device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can ’ t be met (for certain
configurations or co-location with another transmitter), then the FCC authorization is no
longer considered valid and the FCC ID can’t be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module or change RF related parameters in the user
manual of the end product.
l'exposition aux RF L’antenne (ou les antennes) doit être installée de façon à maintenir à tout instant
une distance minimum de au moins 20 cm entre la source de radiation (l’antenne) et toute personne
physique.
Étiquetage du produit final Le module BT111 est étiqueté avec sa propre identification FCC et son
propre numéro de certification IC. Si l’identification FCC et le numéro de certification IC ne sont pas
visibles lorsque le module est installé à l’intérieur d’un autre dispositif, la partie externe du dispositif
dans lequel le module est installé devra également présenter une étiquette faisant référence au
module inclus. Dans ce cas, le produit final devra être étiqueté sur une zone visible avec les
informations suivantes :
« Contient module émetteur identification FCC ID : 2ABA2SFM10R4
« Contient module émetteur IC : 11534A-SFM10R4
RSS-GEN, Sec. 8.3
This radio transmitter (identify the device by certification number, or model number if Category II) has
been approved by Industry Canada to operate with the antenna types listed below with the maximum
permissible gain and required antenna impedance for each antenna type indicated. Antenna types not
included in this list, having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device. Le présent émetteur radio (identifier le dispositif par son numéro de
certification ou son numéro de modèle s’il fait partie du matériel de catégorie I) a été approuvé par
Industrie Canada pour fonctionner avec les types d’antenne énumérés ci-dessous et ayant un gain
admissible maximal et l’impédance requise pour chaque type d’antenne. Les types d’antenne non inclus
dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour
l’exploitation de l’émetteur.
