Safety Warning
Neither the nor EM 100 MODULE / Data Card products may be used in an environment where radio
frequency equipment is prohibited or restricted in its use. This includes aircraft/airports, hospitals, and
other sensitive electronic areas.
Do not operate RF devices in an environment that may be susceptible to radio inter ference
resulting in danger, specifically:
• Areas where prohibited by the law
• Where explosive atmospheres may be present
• Users are advised not to operate the modem while at a refueling point or service station.
• Areas with a potentially explosive atmosphere are often but not always clearly marked.
• Near Medical and life support equipment
• On an aircraft, either on the ground or airborne
• While operating a vehicle
Follow any special rules and regulations and obey all signs and notices. Always
turn off the host device when instructed to do so, or when you suspect that it may cause
interference or danger.
Do not operate your modem in any area where a potentially explosive
atmosphere may exist. Sparks in such areas could cause an explosion or fire resulting
in bodily injury or even death. Be aware and comply with all signs and instructions.
Users are reminded to observe restrictions on the use of radio equipment in fuel depots
(fuel storage and distribution areas), chemical plants or where blasting
operations are in progress.
Potential locations can include gas stations, below deck on boats, chemical
transfer or storage facilities, vehicles using liquefied petroleum gas (such as propane or
butane), areas where the air contains chemicals or particles, such as grain, dust or metal
powders, and any other area where you would normally be advised to turn off your
vehicle engine.

Federal Communications Commission Notice (FCC—United States)
FCC applies to and EM 100 MODULE. Refer to sections on Regulatory Compliance for more
details.
Electronic devices, including computers and Corporationmodems, generate RF energy incidental to their
intended function and are therefore subject to FCC rules and regulations. This equipment
will be tested, and found to be within the acceptable limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a residential environment. This
equipment generates radio frequency energy and is designed for use in accordance with the
manufacturer’s user manual. However, there is no guarantee that interference will not occur in any
particular installation. If this equipment causes harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, you are encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected
• Consult the dealer or an experienced radio/television technician for help
This device complies with Part 15 of the Federal Communications Commission (FCC) Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause
undesired operation.
Radio Frequency Exposure Evaluation Requirements
This Corporationmodule is a radio transmitter and receiver. It is designed and manufactured not to
exceed the exposure limits for radio frequency (RF) energy set by the Federal Communications
Commission (FCC) of the U.S. Government. These limits are part of comprehensive guidelines and

establish permitted levels of RF energy for the general population. The guidelines are based
on standards that were developed by independent scientific organizations through periodic and thorough
evaluation of scientific studies. The standards include a substantial safety margin designed to assure
the safety of all persons, regardless of age and health.
The exposure standard for Corporationdevices including mobile phones and Corporationmodems uses
a unit of measurement known as the Specific Absorption Rate, or SAR. Tests for SAR are conducted
using standard operating positions reviewed by the FCC with the device under test.
This device is to be used only for mobile and fixed applications. 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. The antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter.
transmitting at its highest certified power level in all frequency bands. Although the SAR is
determined at the highest certified power level, the actual SAR level of the phone or modem while
operating can be well below the maximum value. This is because the phone or modem is
designed to operate at multiple power levels so as to use only the power required to reach the network.
In general, the closer you are to a Corporationbase station antenna, the lower the power
output.
Before this device is made available for sale to the public, it must be tested and certified to the
FCC that it does not exceed the limit established by the government-adopted requirement for safe
exposure. The tests are performed in positions and locations (for example, at the ear or worn on
the body) as required by the FCC for each model.
In general, for the United States market, the embedded modules are treated as “mobile devices”
as per FCC CFR47 paragraph 2.1091. A mobile device is defined as “a transmitting device designed to
be used in other than fixed locations and to generally be used in such a way that a separation distance
of at least 20 cm is normally maintained between the transmitter’s radiating structure(s) and the body of
the user or nearby persons.” Manufactures of mobile devices may
be able to submit a Maximum Exposure Rate (MPE) calculation in order to demonstrate SAR
compliance.
