The device's USB connector is adjustable to three positions. Do not force the
hinge past the last position—this may break the connector. For more
information, see the picture on page 18.
Do not use the device with a handheld computer; it is designed only for
®
notebook or desktop computers running Windows Vista, Windows XP,
Windows 2000, or Mac OS X.
Do not handle or operate the device while driving or operating a vehicle. Doing
so may distract you from properly operating the vehicle. In some states and
provinces, operating communication devices while in control of a vehicle is a
criminal offense.
