Working with the Wireless WAN
Depending upon the configuration of your unit, it may have the
additional wireless wide area network (WWAN) feature. After
purchasing a data connection plan from your local GSM cellular
provider, you can communicate from field to office, send e-mail
messages and send text messages.
NOTE: When browsing the internet using the cellular connection,
you must turn off the Wi-Fi (802.11) or the Nomad will default to
the Wi-Fi to browse.
CAUTION:
 DO NOT use your Nomad while driving a moving vehicle.
 DO NOT remove the WWAN antenna unless directed by
support personnel.
 When you are on a plane, in a medical facility or at a gas
station where wireless communication devices are not allowed,
go to Wireless Manager to TURN OFF all wireless
communications. Simply turning the Power key off does not
turn off these communications.
