"Protected Health Information"?

       Last paragraph of a "form" at a hearing-aid business, which is apparently requesting my signature of "consent":


      "You have a right to request that we restrict how we use and disclose your protected health information for the purpose of marketing, treatment, payment or health care operations.  Depending on the nature of your request, we are not required by law to grant your request.  However, if we do decide to grant your request, we are bound by our agreement.  You have the right to revoke this consent in writing, except to the extent we already have used or disclosed your protected health information in reliance on your consent.
       _____________________________      
                                   Signature
                         _______________
                                       Date"
                                     

       This speaks of "your protected health information" twice, but doesn't it sound suspiciously like I'm being asked to sign my consent to leaving such information "unprotected"?  In any case, I couldn't sign it for the reason I gave them:  I didn't understand it.
