Installation Guide - Sierra Wireless compass series Quick Start Manual

Caution:
The Compass USB modem must be 1.0 cm (~ 0.4 inches) or more from the
user and bystanders during operation to satisfy FCC (regulatory) RF exposure
requirements.
It is approved for use with normal-size notebook computers only (typically with 12
inches or larger display screens). For notebook computers with a display screen
smaller than 12 inches or if the orientation of the USB slot does not allow for at
least 1.0 cm between the modem and the user or bystanders, use the provided
extension cable and clip to ensure a safe distance between the modem antenna
and users or bystanders.
To meet FCC requirements, use only the supplied USB extension cable and laptop
clip; other cables and laptop clips should not be used.
