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 of the user’s body.
Check your local standards regarding safe distances, etc.
ATTENTION: Maintenir une distance d'au moins 20 cm (8 po) entre l'antenne du récepteur et le corps de
l'utilisateur ou à proximité de personnes. Le modem n'est pas conçu pour, ou destinés à être
utilisés dans les applications portables, moins de 20 cm du corps de l'utilisateur.
Vérifiez vos normes locales touchant les distances de sécurité, etc..

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.
●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.
Sécurité RF
En raison de la possibilité d'interférences de radiofréquence (RF), il est important que vous suiviez une
quelconque réglementation concernant l'utilisation du matériel radio. Suivez les conseils de sécurité ci-dessous.
●Fonctionnement de votre appareil à proximité d'autres appareils électroniques peuvent causer des
interférences si l'équipement est insuffisamment protégé. Respectez les panneaux d'avertissement et les
recommandations du fabricant.
●Différentes industries et les entreprises limitent l'utilisation des appareils cellulaires. Respectez les
règlements sur l'utilisation des équipements radio dans les dépôts de carburant, les usines chimiques, ou
lorsque des 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.
●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
utilisé.

Multi-Tech's accessory specifications may invalidate the warranty.
●If the device is not working properly, contact Multi-Tech Technical Support.
Handling Precautions
To avoid damage due to the accumulation of static charge, use proper precautions when handling any cellular
device. Although input protection circuitry has been incorporated into the devices to minimize the effect of
static build-up, use proper precautions to avoid exposure to electronic discharge during handling and mounting
the device.
Front Panel Overview
The front panel includes an LED that indicates the status of the link. Another LED indicates whether the modem

Using AT Commands to Verify Signal Strength and Roaming
Status
You can use AT commands to operate, configure, and query your modem. Reference guides document the AT commands.
You can download these guides from the Multi-Tech website.
To verify signal strength and roaming status, you must use a terminal application such as HyperTerminal. To open this
program in Windows XP, go to Start > All Programs > Accessories > Communications > HyperTerminal. Other Windows
operating systems have similar paths to HyperTerminal. See your system’s online Help if you cannot find HyperTerminal.
Verifying Signal Strength
To verify signal strength:
1. Open a terminal program of your choosing.
2. Type AT+CSQ
The modem responds with the received signal strength (rssi) and the channel bit error rate (ber).
RSSI ranges from 0 to 31.
