Connecting the Telephone and Modem Cables
Your supplied accessories may include a ferrite core. The ferrite core is designed
to reduce or eliminate electrical interference when a telephone is connected to
your computer.
1 Unplug your telephone’s cable from the wall jack.
2 Open the supplied ferrite core and place the ferrite core approximately 3-4
inches from the end of the telephone cable.
3 Wrap the telephone cable twice around the ferrite core, lengthwise, with the
cable running directly through the center groove of the core.
4 Close the ferrite core tightly around the telephone cable until it locks.
