Installing the RelayFax SMTP Client on a workstation will also install RFViewer - a simple utility for viewing and printing a fax image file. This software utility will be associated with the proper extensions for opening and printing TIF documents. If an existing software package is found associated with the TIF extension, that registry entry will be saved under the 'edit' shell command. Use the blue arrow keys to move from page to page in a multi-page fax.
