How to Insert the Modem
into the Computer
NOTE: Before installing your
modem, write its serial number
somewhere where it will be handy
during software installation. (You’ll
find the serial number underneath the
bar code on the white sticker on the
modem and on the outside of the box
the modem came in.) If you ever need
to call our customer support
department, a customer support
representative will ask you for the
serial number. This will help him or
her identify your modem.
