                1. Megahertz will gladly exchange the product for the XJ124FM
                   modem model.  This is the XJACK version of the modem and
                   has been verified to be compatible with the Ascentia 900N.
                   Contact the Megahertz Support Center at (801) 320-7000.
                2. Megahertz will gladly upgrade the modem through their
                   upgrade program.  Contact Megahertz Sales Support at
                   (800) 527-8677, ext. 6772.  The price is dependent upon the
                   new modem chosen.
                3. Return the modem to the place of purchase for a full refund.
                   Contact the Megahertz Support Center  at (801) 320-7000 if
                   there are any difficulties in returning the item.
                4. If the modem in question is an OEM (Original Equipment
                   Manufacturer) modem that appears to be a Megahertz modem,
                   return the item to the company whose name appears on the
                   modem.  Megahertz can not provide support for any
                   non-branded Megahertz product.
