(TI-73 Explorer™ Calculator Users) A Communication Failure 
occurs at times even though the calculator is plugged in. 
If you get a failure to communicate on the calculator, it probably 
means that two things were trying to happen at once. For example, 
if you take a screen capture while someone is logging in, you may 
have to refresh screenshots. Simply retry on the calculator or 
computer.
(TI-73 Explorer™ Calculator Users) Some students miss a "Force to 
Students" transmission.
If a teacher forces a transfer and the calculator does not 
automatically receive the file, the file is still there waiting for the 
student. From the TI-Navigator™ Home screen on the NavNet App, 
the calculator user simply selectes 3. TRANSFERS & 1. AUTO 
SEND/RECV to request any files waiting for them.
