First thing I encountered powering up if to perform calibration cancel/ok and I was stumped.
- how do you respond
Hours later I found I place in manual stating Assign 1-4 is cancel or no, and assign 5-8 is ok or yes.
There is plenty room to have little guides like this for user, not needing manual for simple things.
After calibration it says OK - then what to proceed.
Sometimes they overdo it, like when naming and selecting category, Far left a symbol I read as return which was meant as Back. Just writing Back instead and you know the drill.
There are more examples, just a few mentioned here.
Where possible, guide user with simple things....
