General Safety
The modem is designed for and intended to be used in fixed and mobile applications. “Fixed” means that the device is physically
secured at one location and is not able to be easily moved to another location. “Mobile” means that the device is designed to be
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 body of the user.
