OEM/Integrators Installation Manual
Important Notice to OEM integrators
1. This module is limited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and different antenna configurations
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify
compliance as a composite system. When testing the host device for compliance with Part
15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the
transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation
should confirm that the module's intentional emissions are compliant (i.e. fundamental and out of band
emissions). The host manufacturer must verify that there are no additional unintentional emissions other
than what is permitted in Part 15 Subpart B or emissions are complaint with the transmitter(s) rule(s).
The Grantee will provide guidance to the host manufacturer for Part 15 B requirements if needed.
End Product Labeling
When the module is installed in the host device, the FCC/IC ID label must be visible through a window on
the final device or it must be visible when an access panel, door or cover is easily re-moved. If not, a
second label must be placed on the outside of the final device that contains the following text: “Contains
FCC ID: XMR2019SC600NA ”
“Contains IC: 10224A-2019SC600NA “
The FCC ID/IC ID can be used only when all FCC/IC compliance requirements are met.

Smart LTE Module Series
SC600Y&SC600T Hardware Design
SC600Y&SC600T_Hardware_Design 11 / 128
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC/IC authorization is no longer considered valid and the FCC ID/IC
ID cannot 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/IC 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 in the user’s manual of the end product which integrates this module. The end
user manual shall include all required regulatory information/warning as show in this manual.
Federal Communication Commission Interference Statement
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.
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 of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for compliance could void

the user's authority to operate this equipment. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
Industry Canada Statement
This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired
operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement."
The device could automatically discontinue transmission in case of absence of information to transmit, or
operational failure. Note that this is not intended to prohibit transmission of control or signaling information
or the use of repetitive codes where required by the technology.
The device for operation in the band 5150–5250 MHz is only for indoor use to reduce the potential for
harmful interference to co-channel mobile satellite systems;
The maximum antenna gain permitted for devices in the bands 5250–5350 MHz and 5470–5725 MHz
shall comply with the e.i.r.p. limit; and
The maximum antenna gain permitted for devices in the band 5725–5825 MHz shall comply with the
e.i.r.p. limits specified for point-to-point and non point-to-point operation as appropriate.
L'appareil peut interrompre automatiquement la transmission en cas d'absence d'informations à
transmettre ou de panne opérationnelle. Notez que ceci n'est pas destiné à interdire la transmission
d'informations de contrôle ou de signalisation ou l'utilisation de codes répétitifs lorsque cela est requis par
la technologie.
Le dispositif utilisédans la bande 5150-5250 MHz est réservéàune utilisation en intérieur afin de réduire
le risque de brouillage préjudiciable aux systèmes mobiles par satellite dans le même canal;
Le gain d'antenne maximal autorisé pour les dispositifs dans les bandes 5250-5350 MHz et 5470-5725
MHz doit être conforme àla norme e.r.p. limite; et
Le gain d'antenne maximal autorisépour les appareils de la bande 5725-5825 MHz doit être conforme à
la norme e.i.r.p. les limites spécifiées pour un fonctionnement point àpoint et non point àpoint, selon le
cas.

1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating SC600Y&SC600T modules. Manufacturers of the
cellular terminal should send the following safety information to users and operating personnel, and
incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no
liability for customers’ failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an
accident. Using a mobile while driving (even with a handsfree kit) causes
distraction and can lead to an accident. Please comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. The operation
of wireless appliances in an aircraft is forbidden to prevent interference with
communication systems. If the device offers an Airplane Mode, then it should be
enabled prior to boarding an aircraft. Please consult the airline staff for more
restrictions on the use of wireless devices on boarding the aircraft.
Wireless devices may cause interference on sensitive medical equipment, so
please be aware of the restrictions on the use of wireless devices when in
hospitals, clinics or other healthcare facilities.
Cellular terminals or mobiles operating over radio signals and cellular network
cannot be guaranteed to connect in all possible conditions (for example, with
unpaid bills or with an invalid (U)SIM card). When emergent help is needed in such
conditions, please remember using emergency call. In order to make or receive a
call, the cellular terminal or mobile must be switched on in a service area with
adequate cellular signal strength.
The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it
receives and transmits radio frequency signals. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potentially explosive atmospheres include fuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
