How to Insert the Modem
into the Computer
NOTE: Before installing your
modem, write its serial number in the
space provided on the first page of
this manual. (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.
