4) Training Session Options:

    A.) The interactive VISITview training session. (To be used with a VISIT instructor leading the session ). Click here to signup for teletraining. The session will last about 75 minutes. This teletraining session uses the VISITview software, where Windows PC with an Internet connection is needed.

    B.) Web-based training session - a "stand alone" version viewed via a Web browser, with embedded talking points included. This lesson version may be viewed at any time. These slides are ideal for printing from the web-browser, just print preview first to choose portrait or landscape mode. Best viewed with Internet Explorer or Netscape (prior to version 6).

    C.) local Visitview session - This is the same version of the lesson used in a "live" VISITview teletraining session, but no connection is made to an external VISITview server. You may download the file off this page and go through the lesson on your own in "local mode" by starting the "visitlocal.bat" file. Talking points are not included in this lesson version, but can be viewed in a separate Web browser ( or printed out beforehand).
