54 X4 ADSL Modem User’s Manual
PROBLEM : Why do I hear static or noise when I’m using
my telephone?
SOLUTION: If that phone does not have its own filter, you may
hear static or high-pitched noise if you make a phone
call while your ADSL modem is on. A filter also
prevents a phone from interfering with, or dropping,
your DSL connection.
PROBLEM: I accidentally unplugged the USB cable while
using my modem. This resulted in a general
protection fault (GPF) error message. What
should I do?
SOLUTION: You must plug the modem back in and restart your
computer to rectify this problem.
