Multi-Tech Systems, Inc. MultiModem rCell User Guide 6
Chapter 1 –Introduction and Description
Introduction
This guide describes the MultiModem® rCell intelligent wireless routers with an Ethernet II interface. The
MultiModem rCell Router is configured for one of three connectivity modes: always-on, wake-up on ring, or dial-
on demand. The always-on network connection automatically establishes a wireless data connection and allows
for around the clock surveillance, monitoring or real time data acquisition of any remote Ethernet device such as a
Web camera. If the data link is dropped in the event of poor reception or a complete loss of service, it
automatically re-establishes the data link. The wake-up on ring configuration allows the router to “wake up” and
initiate a connection when it detects an incoming ring. For security reasons, you can setup the router to wake up
based on a particular caller ID number. This configuration is ideal for reducing the costs associated with the
modem being online and available 24/7. When configured for dial-on demand, the router only accesses the
Internet when data is present. This configuration is ideal for sharing Internet access among networked PCs.

RF Safety
Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
regarding the use of radio equipment. 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 of the user’s body.
Check your local standards regarding safe distances, etc.
●Operating your 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 restrict the use of cellular devices. Respect restrictions on the use of radio
equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow restrictions for
any environment where you operate the device.
●Do not place the antenna outdoors.
●Switch OFF your wireless device when in an aircraft. Using portable electronic devices 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 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.

opérations de dynamitage sont en cours. Suivez restrictions pour n'importe quel environnement où vous
utilisez l'appareil.
●Ne pas placer l'antenne à l'extérieur.

Chapter 1 –Introduction and Description
Multi-Tech Systems, Inc. MultiModem rCell User Guide 8
●Éteignez votre appareil sans fil dans un avion. Utilisant des dispositifs électroniques portables dans un avion
peut mettre en danger le fonctionnement de l'avion, peut perturber le réseau cellulaire, et est illégal. Le non-
respect de cette restriction peut entraîner la suspension ou le refus des services cellulaires au contrevenant,
une action en justice, ou les deux.
●Éteignez votre appareil sans fil lorsque autour de l'essence ou pompes diesel-carburant et avant de remplir
votre véhicule avec du carburant.
●Éteignez votre appareil sans fil dans les hôpitaux et tout autre endroit où l'équipement médical peut être

ATTENTION: Risque d'explosion si cette batterie est remplacée par un type incorrect. Jetez les batteries
conformément aux instructions.
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.

Chapter 1 –Introduction and Description
9 Multi-Tech Systems, Inc. MultiModem rCell User Guide
●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).

Access Point Names
Your wireless service provider assigns an APN (Access Point Name), but you may have to ask for it. An access point
is an IP network to which a MultiModem rCell Router connects. The Web Management software asks for the APN
on the Wizard Setup screen and the PPP screen.
Provider Fees
Your provider charges you for data usage. Check with your provider for rates and limitations. If you plan to use the
router for large amounts of data transfers, Multi-Tech recommends an unlimited data plan with your account.
Multi-Tech is not responsible for any charges relating to your cellular bill.
