Important Notice

Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.

Safety and Hazards

Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is

on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When

operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.

Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door

The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.

4. Legal Information

4.1. FCC Regulations

The HL7548 module has been granted modular approval for mobile applications. Integrators may use
the HL7548 module in their final products without additional FCC certification if they meet the
following conditions. Otherwise, additional FCC approvals must be obtained.

1. At least 20 cm separation distance between the antenna and the user’s body must be
maintained at all times.

2. To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only
exposure condition must not exceed:

 9.01 dBi in LTE Band 2
 6.00 dBi in LTE Band 4
 10.42 dBi in LTE Band 5
 9.73 dBi in LTE Band 17

3. This device and its antenna(s) must not transmit be co-located or operating in conjunction
with any other antenna or transmitter, except in accordance with FCC multi-transmitter RF
exposure product procedures.

4. The RF signal must be routed on the application board using tracks with a 50Ω characteristic
impedance. Basically, the characteristic impedance depends on the dielectric, the track width
and the ground plane spacing. In order to respect this constraint, Sierra Wireless
recommends using MicroStrip or StripLine structure and computing the Tracks width with a
simulation tool (like AppCad shown in the figure below and that is available free of charge at

http://www.agilent.com).

TBC Rev 1.0 January 28, 2015 19

User Guide Legal Information

If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital,
analog or supply).

If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure. An
example of proper routing is shown in the figure below.

Stripline and Coplanar design requires having a correct ground plane at both sides.
Consequently, it is necessary to add some vias along the RF path. It is recommended to use
Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not
shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring
electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (micro­controllers, etc.) may degrade the reception performances. The antenna connector is
intended to be directly connected to a 50Ω antenna and no matching is needed.

5. A label must be affixed to the outside of the end product into which the HL7548 module is
incorporated, with a statement similar to the following:

This device contains FCC ID: N7NHL7548

6. A user manual with the end product must clearly indicate the operating requirements and
conditions that must be observed to ensure compliance with current FCC RF exposure
guidelines.

The end product with an embedded HL7548 module may also need to pass the FCC Part 15
unintentional emission testing requirements and be properly authorized per FCC Part 15.

Note: If this module is intended for use in a portable device, you are responsible for separate approval to

satisfy the SAR requirements of FCC Part 2.1093.

4.2. IC Regulations

IC Radiation Exposure Statement:

This equipment complies with IC RSS-102 radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with minimum
distance 20cm between the radiator and your body.

This device and its antenna(s) must not transmit be co-located or operating in conjunction
with any other antenna or transmitter, except in accordance with IC multi-transmitter RF
exposure product procedures.

This Class B digital apparatus complies with Canadian ICES-003.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To
reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p) is not more than necessary for
successful communication.

Labeling Requirements for the Host Device (from Section 7.2 of RSP-100, Issue 10,
November 2014): The host device shall be properly labeled to identify the module within the
host device. The Industry Canada certification label of a module shall be clearly visible at all
times when installed in the host device, otherwise the host device must be labeled to display
the Industry Canada certification number of the module, preceded by the words – Contains

TBC Rev 1.0 January 28, 2015 20

User Guide Legal Information

transmitter moduleǁ, or the word – Containsǁ, or similar wording expressing the same
meaning, as follows: Contains transmitter module IC: 2417C-HL7548.

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
operating with the maximum permissible gain and required antenna impedance for each
antenna type indicated:

 9.01 dBi in LTE Band 2
 6.00 dBi in LTE Band 4
 10.42 dBi in LTE Band 5
 9.73 dBi in LTE Band 17

Antenna types having a gain greater than the maximum gain indicated for that type are strictly
prohibited for use with this device.
