Hello; Sorry for the unreadable message. I try and remember not to post to the list with my notetaker but after reading messages I sometimes forget. The handiham remote base is correctly HF. I was curious about the usability of other remote bases. As for system access I have no idea. I am wondering if jfw or window eyes can be put on a thumb drive and be used on what ever computer is handy? I suspect not but as you can see I have been wrong before. That would be a nice feature. Richard
