If you are a print reader, before you watch the Lesson 2 video, we recommend you emboss the Lesson 2 Activities.brf file* or print the Lesson 2 Activities.pdf file. If you are using Duxbury, before opening any BRF files in Duxbury, go into the Global menu. Select “Formatted Braille Importer” and then check the box for “Read formatted braille without interpretation” at the top of the window. This will ensure that nothing is changed when opening the BRF files.  We suggest you wait to access the Lesson 2 PPT.pdf file until after you watch the video.

* If you have difficulty downloading a BRF file, see these tips.
