Safety
General Safety
The modem is designed for and intended to be used in fixed and mobile applications. Fixed means the device is
physically secured at one location and cannot be easily moved to another location. Mobile means the device is
used in other than fixed locations.
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.
RF Interference Issues
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.
● Switch OFF your wireless device when in an aircraft. Using cellular telephones in an aircraft may endanger
aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction may lead to
suspension or denial of cellular telephone services to the offender, legal action, or both.
● Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle
with fuel.
● Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.
● Respect restrictions on the use of radio equipment in fuel depots, chemical plants, or where blasting
operations are in progress.
● 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.

Chapter 1 – Product Description and Specifications
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).
Vehicle Safety
● Do not use this device while driving.
● Respect national regulations on the use of cellular telephones in vehicles.
● If incorrectly installed in a vehicle, operating the wireless device could interfere with the vehicle’s electronics.
To avoid such problems, use qualified personnel to install the device. The installer should verify that vehicle
electronics are protected from interference.
● Using an alert device to operate a vehicle’s lights or horn is not permitted on public roads.
Maintenance of the Wireless MultiModem
Your wireless MultiModem is the product of advanced engineering, design, and craftsmanship and should be treated with
care. The suggestions below will help you to enjoy this product for many years.
● Do not expose the MultiModem to any extreme environment where the temperature or humidity is high.
● Do not attempt to disassemble the MultiModem. There are no user serviceable parts inside.
● Do not expose the MultiModem to water, rain, or spilled beverages. It is not waterproof.
● Do not abuse your MultiModem by dropping, knocking, or violently shaking it. Rough handling can damage it.
● Do not place the MultiModem alongside computer discs, credit or travel cards, or other magnetic media. The
information contained on discs or cards may be affected by the phone.
● Using accessories that Multi-Tech has not authorized or that are no compliant with Multi-Tech’s accessory
specifications may invalidate the MultiModem warranty.

If the MultiModem is not working properly, contact Multi-Tech Technical Support.
Handling Precautions
Handle all electronic devices with certain precautions to avoid damage due to the static charge accumulation.
Although input protection circuitry has been incorporated into the devices to minimize the effect of this static
build up, proper precautions should be taken to avoid exposure to electrostatic discharge during handling and
mounting.
