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
is open. Sierra Wireless modems may be used at this time.
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.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.

This value has to be guaranteed during the burst.
Note:
Load capacitance for VBAT is around 32µF ± 20% embedded inside the accessory board.
2.2.
Power Off Sequence
To power the HL7588 Accessory Board off:
1. Put the accessory board in low power mode (LPM) by sending either AT+KSLEEP=1 or
AT+CPWROFF=1.
2. Wait for at least 10 seconds.
3. Remove the power supply to VBAT.
2.3.
Sleep Mode Management
Use AT+KSLEEP=1 to allow the accessory board to automatically enter sleep mode while the USB
interface is in use.
When AT+KSLEEP=2, the accessory board will never enter sleep mode.

4. ESD Guidelines
4.1.
SIM Card
Decoupling capacitors must be added according to the drawings below as close as possible to the
SIM card connectors on UIM1_CLK, UIM1_RST, UIM1_VCC and UIM1_DATA signals to avoid EMC
issues and to comply with the requirements of ETSI and 3GPP standards covering the SIM electrical
interface.
A typical schematic including SIM detection is provided below.

ESD Guidelines
USB
When the USB interface is externally accessible, it is required to have ESD protection on the USB_D+
and USB_D- signals.
Figure 3.
ESD Protection for USB
Sierra Wireless recommends using a 90Ω DLP0NSN900HL2L EMC filter and an RCLAMP0503N or
ESD5V3U2U-03LRH ESD diode.

5. FCC Regulations
The HL7588 Accessory Board has been granted modular approval for mobile applications. Integrators
may use the HL7588 Accessory Board 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:





7.5 dBi in Band 2
5.0 dBi in Band 4
9.0 dBi in Band 5
9.0 dBi in Band 13
9.0 dBi in Band 17
3. The AR7552 modem may transmit simultaneously with other collocated radio
transmitters within a host device, provided the following conditions are met:
 Each collocated radio transmitter has been certfied by FCC / IC for mobile application.
 At least 20 cm separation distance between the antennas of the collocated transmitters
and the user’s body must be maintained at all times.
 The output power and antenna gain must not exceed the limits and configurations
stipulated in the following table.

4. The HL7588 Accessory Board must not transmit simultaneously with other collocated radio
transmitters within a host device.
5. 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
4119383
Rev 1.1
June 06, 2016
14
Hardware Integration Guide
FCC Regulations
http://www.agilent.com).
If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital,
analog or supply).
6. A label must be affixed to the outside of the end product into which the HL7588 Accessory
Board is incorporated, with a statement similar to the following:
This device contains FCC ID: N7NHL7588
7. 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 HL7588 Accessory Board may also need to pass the FCC Part 15
unintentional emission testing requirements and be properly authorized per FCC Part 15.
Note:
4119383
If this accessory board is intended for use in a portable device, you are responsible for separate
approval to satisfy the SAR requirements of FCC Part 2.1093.
