Q: What is the difference between the blue and white remotes? Can I replace the blue remote if it has been lost?
A: There are no technical differences between the blue and white remotes--the color difference simply allows you to keep track of your own remotes. The white remotes are those sold to students--we do not sell the blue remotes to students. Each instructor kit includes two blue remotes (one for the instructor's remote function and one as a possible loaner to students).
A white remote can be substituted for the blue remote without loss of functionality. However, if you need a blue remote replacement, contact firstname.lastname@example.org.
