Safety Warnings

Ethernet Ports

Caution: The Ethernet ports and command ports are not designed to be connected to a public
telecommunication network.

RF Safety

Follow any special regulations regarding the use of radio equipment due to the possibility of radio frequency (RF)
interference. Follow the safety advice given below.
Caution: Maintain a separation distance of at least 20 cm (8 inches) between the transmitter's antenna and the
body of the user or nearby persons. The modem is not designed for or intended to be used in portable
applications within 20 cm (8 inches) of the user's body.
Check your local standards regarding safe distances, etc.
●
Operating your wireless device close to other electronic equipment may cause interference if the equipment
is inadequately protected. Observe any warning signs and manufacturers' recommendations.
●
Different industries and businesses have their own restrictions governing the use of cellular devices. Please
observe the local restrictions of the environment where you intend to operate the cell modem.
●
Do not place the antenna outdoors.

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).
