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 the module. Manufacturers of the cellular terminal
should notify users and operating personnel of the following safety information by incorporating these
guidelines into all manuals of the product. Otherwise, Quectel assumes no liability for customers’ failure to
comply with these precautions.
Full attention must be paid 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 there is an Airplane Mode, it should be enabled prior to
boarding an aircraft. Please consult the airline staff for more restrictions on the use
of wireless devices on an 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 signal and cellular network
cannot be guaranteed to connect in certain conditions, such as when the mobile bill
is unpaid or the (U)SIM card is invalid. When emergency help is needed in such
conditions, use emergency call if the device supports it. 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. In an emergency, the device with emergency call
function cannot be used as the only contact method considering network
connection cannot be guaranteed under all circumstances.
The cellular terminal or mobile contains a transceiver. When it is ON, it receives
and transmits radio frequency signals. RF interference can occur if it is used close
to TV sets, radios, computers or other electric equipment.
In locations with explosive or potentially explosive atmospheres, obey all posted
signs and turn off wireless devices such as mobile phone or other cellular
terminals. Areas with explosive or potentially explosive atmospheres include
fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities,
and areas where the air contains chemicals or particles such as grain, dust or
metal powders.

conditions that must be observed to ensure compliance with current FCC RF exposure guidelines.
For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is
required to satisfy the SAR requirements of FCC Part 2.1093
If the device is used for other equipment that separate approval is required for all other operating
configurations, including portable configurations with respect to 2.1093 and different antenna
configurations.
For this device, OEM integrators must be provided with labeling instructions of finished products.
Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:
A certified modular has the option to use a permanently affixed label, or an electronic label. For a
permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2

LTE Standard Module Series
EM05-G Hardware Design
EM05-G_Hardware_Design 11 / 69
Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining
to the OEM the labeling requirements, options and OEM user manual instructions that are required (see
next paragraph).
For a host using a certified modular with a standard fixed label, if (1) the module’s FCC ID is not visible
when installed in the host, or (2) if the host is marketed so that end users do not have straightforward
commonly used methods for access to remove the module so that the FCC ID of the module is visible;
then an additional permanent label referring to the enclosed module: “Contains Transmitter Module FCC
ID: XMR2021EM05G” or “Contains FCC ID: 10224A-2021EM05G” must be used. The host OEM user
manual must also contain clear instructions on how end users can find and/or access the module and the
FCC ID.
The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for
unintentional radiators in order to be properly authorized for operation as a Part 15 digital device.
The user’s manual or instruction manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment. In cases where the manual is provided only in a form other
than paper, such as on a computer disk or over the Internet, the information required by this section may
be included in the manual in that alternative form, provided the user can reasonably be expected to have
the capability to access information in that form.
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.
Changes or modifications not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.
To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring
compliance with the module(s) installed and fully operational. For example, if a host was previously
authorized as an unintentional radiator under the Supplier’s Declaration of Conformity procedure without
a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring
that the after the module is installed and operational the host continues to be compliant with the Part 15B
unintentional radiator requirements.
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

1. 1) Within operating temperature range, the module is 3GPP compliant.
2. 2) Within extended temperature range, the module remains the ability to establish and maintain SMS,
data transmission, etc. There is no unrecoverable malfunction. There are also no effects on radio
spectrum and no harm to radio network. Only one or more parameters like Pout might reduce in their
value and exceed the specified tolerances. When the temperature returns to normal operating
temperature levels, the module will meet 3GPP specifications again.
