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. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers an
Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals, clinics or other health care
facilities. These requests are designed to prevent possible interference with
sensitive medical equipment.
Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid (U)SIM card. While you are in this condition and need
emergent help, please remember using emergency call. In order to make or
receive a call, the cellular terminal or mobile must be switched on and in a service
area with adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON,
it receives and transmits radio frequency energy. 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
chemicals or particles such as grain, dust or metal powders, etc.

2.2. Directives and Standards
The BG96 module is designed to comply with the FCC statements. FCC ID: XMR201707BG96
The Host system using BG96 should have label “contains FCC ID: XMR201707BG96
2.2.1. FCC Statement
According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a
mobile device.
And the following conditions must be met:
1. This Modular Approval is limited to OEM installation for mobile and fixed applications only.
The antenna installation and operating configurations of this transmitter, including any applicable
source-based time- averaging duty factor, antenna gain and cable loss must satisfy MPE categorical
Exclusion Requirements of 2.1091.
2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the user’s
body and must not transmit simultaneously with any other antenna or transmitter.
3. A label with the following statements must be attached to the host end product: This device contains
FCC ID: XMR201707BG96.
4. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF
radiation, maximum antenna gain (including cable loss) must not exceed:
❒LTE B1/B2/B3/B4/B5/B8/B12/B13/B20/B26/B28 <4dBi
❒GSM 850/900/1800/1900 <4dBi
5. This module must not transmit simultaneously with any other antenna or transmitter
6. The host end product must include a user manual that clearly defines operating requirements and
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 label led with an FCC ID - Section 2.926 (see 2.2
Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining
BG96_Hardware_Design Confidential / Released 12 / 71
LTE Module Series
Features
Details
BG96 Hardware Design
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 straight forward
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:XMR201707BG96” or “Contains FCC ID: XMR201707BG96” 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 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.

2.
1)
Within operation temperature range, the module is 3GPP compliant.
3.
2)
Within extended temperature range, the module remains the ability to establish and maintain a
voice, SMS, data transmission, emergency call, 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
P
out
might reduce in their value and exceed the specified tolerances. When the temperature returns to
the normal operating temperature levels, the module will meet 3GPP specifications again.
