Before YOU Begin

You should now contact your local cable company and verify the following:

∙You have cable service to your home that supports two-way cable modem access. If your cable company does not provide two-way service, the

U.S. Robotics Cable Modem CMX will not be able to communicate with your cable company’s Internet access service. You should immediately consult your cable company and place of purchase to determine the proper U.S. Robotics cable modem that will work with your cable company. You can also visit the following URL for additional information:

∙Your cable company has set up your cable Internet access account. Your cable company will establish an Internet

access account that will allow you to send and receive e-mail, access the World Wide Web, and receive other Internet services. This account must be established before you can use your cable modem.

∙You have a cable line near your PC and it has been prepared for cable modem service. If you do not have a cable line in your home that supports two-way cable modem access or if your current cable connection is not conveniently located near your computer, your cable company can install one. If you use your cable line for cable television access, your cable company can also install an additional line for use with your cable modem.
