This document can help you quickly understand module interface specifications, electrical and
mechanical details as well as other related information of SC20 module. Associated with application notes
and user guide, you can use SC20 module to design and set up mobile applications easily.
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 SC20 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel and to incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the
customer’s failure to comply with these precautions.

7.6. Elect
The module is not protected against electrostatic discharge (ESD) in general. Consequently, it should be
subject to ESD handling precautions that are typically applied to ESD sensitive components. Proper ESD
handling and packaging procedures must be applied throughout the processing, handling and operation
of any application that incorporates the module.

2. After this bag is opened, devices that will be subjected to reflow soldering or other high temperature
process must be:
Mounted within 72 hours at factory conditions of ≤ 30ºC/60%RH.
Stored at < 10% RH.
3. Devices require baking before mounting, if:
Humidity indicator card is > 10% when ambient temperature is 23ºC±5ºC.
Mounting cannot be finished within 72 hours at factory conditions of ≤ 30ºC/60% RH.
4. If baking is required, devices may be baked for 48 hours at 125ºC±5ºC.

It is suggested that the peak reflow temperature is from 235 to 245ºC (for SnAg3.0Cu0.5 alloy). The
absolute maximum reflow temperature is 260ºC. To avoid damage to the module caused by repeated
heating, it is suggested that the module should be mounted after reflow soldering for the other side of
PCB has been completed. Recommended reflow soldering thermal profile is shown below:

classes are product dependent, and determine the maximum achievable data rates in both the uplink and
downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots,
while the second number indicates the amount of uplink timeslots. The active slots determine the total
number of slots the GPRS device can use simultaneously for both uplink and downlink communications.

interference received, including interference that may cause undesired operation.
This device 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 radiated
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 or more 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.
Caution: Changes or modifications not expressly approved by the party responsible for compliance
could void the user‘s authority to operate the equipment.

14.5. IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC
compliance requirement of the end product, which integrates this module. 20cm minimum distance
has to be able to be maintained between the antenna and the users for the host this module is
integrated into. Under such configuration, the FCC radiation exposure limits set forth for an
population/uncontrolled environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's
authority to operate this equipment.
14.6. US
In
the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to be
informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment can be
satisfied. The end user has to also be informed that any changes or modifications not expressly
approved by the manufacturer could void the user's authority to operate this equipment. If the size of
the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be
available in the users manual: This device complies with Part 15 of 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.
