Interference with Pacemakers and Other Medical Devices
Potential interference
Radiofrequency energy (RF) from cellular devices can interact with some electronic devices. This is electromagnetic
interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted cardiac
pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
■ Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
■ Cause the pacemaker to deliver the pulses irregularly.
■ Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause
a problem.
■ Keep the device on the opposite the side of the body from the pacemaker to add extra distance
between the pacemaker and the device.
■ Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt
or jacket pocket directly over the pacemaker).
Device Maintenance
When maintaining your device:
■ Do not attempt to disassemble the device. There are no user serviceable parts inside.
■ Do not expose your device to any extreme environment where the temperature or humidity is high.
■ Do not expose the device to water, rain, or spilled beverages. It is not waterproof.
■ Do not place the device alongside computer discs, credit or travel cards, or other magnetic media. The
information contained on discs or cards may be affected by the device.
■ Using accessories, such as antennas, that Multi-Tech has not authorized or that are not compliant with
Multi-Tech's accessory specifications may invalidate the warranty.
If the device is not working properly, contact Multi-Tech Technical Support.

Shell Commands
Testing Serial Ports
To test the serial ports created by the driver, type in a shell:
Note: Sending ATE0 is required, to avoid issues in the terminal output. It prevents the sending/receiving
spurious characters to/from the modem when used with the Linux commands “echo” and “cat”
You can perform the same test using the other interface (ttyACM1 ttyACM3).
Create a PPP Connection
Most recent Linux distributions have GUI tools for creating PPP connections; the following instructions are for
creating a PPP connection through command line interface.
PPP support must be compiled into the kernel; pppd and chat programs are also required.
pppd needs two scripts: the first script performs the environment setting and calls the second script, which is used
by the chat program. For creating a PPP connection type:
# pppd file /etc/pppd_script &
Example
# Debug info from pppd
debug
#kdebug 4
# Most phones don't reply to LCP echos
lcp-echo-failure 3
lcp-echo-interval 3
# Keep pppd attached to the terminal
# Comment this to get daemon mode pppd

BASIC OPERATIONS
Basic Operations
Interacting with Your Device Overview
This section describes how to use AT commands to interact with your device. Using terminal software such as
Kermit, you can issue AT commands to communicate with and configure your modem. The AT commands let you
establish, read and modify device parameters and help you control how the device operates. This section
documents basic interactions with your device, such as verifying signal strength and network registrations, sending
and reading SMS text messages, and sending and receiving data.
Generally, USB modems are used as unintelligent bit pipes. In Windows, this means you create a dial-up network
connection that uses the Windows IP stack to use the modem to create a PPP connection to the cellular network.
The modem is assigned an IP address from the cellular carrier. This connection provides Internet access and is the
basis for TCP/IP communication for sending and receiving email, creating TCP/UDP Sockets, or putting and getting
files from an FTP server.
In Linux, PPPD is used to dial the modem and create the connection to the cellular TCP/IP network. This provides
Internet access for sending and receiving email, creating TCP/UDP Sockets, or putting and getting files from an FTP
server.
Related Documentation
Related documentation for using HSPA+ H5 devices:
■ HSPA-H5 AT Commands Reference Guide (S000528) provides for additional information on AT commands
available for your device. The Introduction chapter describes command formatting, syntax, and other basic
information.
■ Configuring Devices: Using AT RUN, Setting up Digital Voice Interface, and Configuring Ports Reference
Guide (S000552).
Before You Begin
Before you begin:
■ If you have not done so, install any drivers. Refer to the separate driver installation guide for your device.
■ Power up your device and ensure it is connected to the computer that you use to issue AT commands.
■ Install terminal software that can communicate with the device, such as HyperTerminal, TerraTerm, Kermit,
or Putty.
Preparing the Modem for a Data Connection
Set the APN by issuing the following command where <APN Name> is the APN assigned by the carrier.
■ AT+CGDCONT=1,"IP","<APN Name>
Check for registration by issuing AT+CREG?<cr> and wait for the response. If the second value of the response (for
example, +CREG:x,y) is 1, then the modem is registered on the home network. If y=5, then the modem is registered
but roaming. See the AT Command reference guide for other possible responses. If the second value is not 1 or 5,
then do not attempt to dial. Wait ~5 seconds for the modem to finish registration and check +CREG again.

BASIC OPERATIONS
Using the Radio IP Stack to Make a Data Connection
Connect by issuing the command: AT#SGACT=1,1 (using PDP context #1).
Using the Host System IP Stack to Make a Data Connection
This device only supports packet data connections, such as dial-up networking. To make a data connection, you
must use a PPP dialer. If your carrier requires a username and password for the Internet connection, be sure to
enter that information into the PPP dialer. Dial up using ATD*99***1# (using PDP context #1).
Disconnect a Data Connection Using an Internal IP Stack
Issue the following command to disconnect: AT#SGACT=1,0
How to Disconnect a Data Connection Using Host IP Stack
Issue the following command to disconnect: AT#SGACT-1,0.
Using Command Mode and Online Data Mode
Modems have two operation modes, command and online data. When you power up the modem it is in command
mode and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. They allow you to establish, read, and modify
device parameters and control how the modem works. The device can also generate responses to AT commands
that help determine the modem’s current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem’s
default data format, which is:
■ Speed: 115,200 bps
■ Data bits: 8
■ Parity: none
■ Stop bit: 1
■ Flow control: hardware
To confirm you are communicating with the device:
■ Type AT and press Enter.
If the device responds with OK, you are communicating with the device.

WEEE Directive
The WEEE Directive places an obligation on EU-based manufacturers, distributors, retailers, and importers to takeback electronics products at the end of their useful life. A sister directive, ROHS (Restriction of Hazardous
Substances) complements the WEEE Directive by banning the presence of specific hazardous substances in the
products at the design phase. The WEEE Directive covers all Multi-Tech products imported into the EU as of August
13, 2005. EU-based manufacturers, distributors, retailers and importers are obliged to finance the costs of recovery
from municipal collection points, reuse, and recycling of specified percentages per the WEEE requirements.
Instructions for Disposal of WEEE by Users in the European Union
The symbol shown below is on the product or on its packaging, which indicates that this product must not be
disposed of with other waste. Instead, it is the user's responsibility to dispose of their waste equipment by handing

REACH Statement
Registration of Substances
After careful review of the legislation and specifically the definition of an “article” as defined in EC Regulation
1907/2006, Title II, Chapter 1, Article 7.1(a)(b), it is our current view Multi-Tech Systems, Inc. products would be
considered as “articles”. In light of the definition in § 7.1(b) which requires registration of an article only if it
contains a regulated substance that “is intended to be released under normal or reasonably foreseeable conditions
of use,” Our analysis is that Multi-Tech Systems, Inc. products constitute nonregisterable articles for their intended
and anticipated use.
Substances of Very High Concern (SVHC)
Per the candidate list of Substances of Very High Concern (SVHC) published October 28, 2008 we have reviewed
these substances and certify the Multi-Tech Systems, Inc. products are compliant per the EU “REACH”
requirements of less than 0.1% (w/w) for each substance. If new SVHC candidates are published by the European
Chemicals Agency, and relevant substances have been confirmed, that exceeds greater than 0.1% (w/w), MultiTech Systems, Inc. will provide updated compliance status.
Multi-Tech Systems, Inc. also declares it has been duly diligent in ensuring that the products supplied are compliant
through a formalized process which includes collection and validation of materials declarations and selective
materials analysis where appropriate. This data is controlled as part of a formal quality system and will be made
