Love the feature set and the functionality but one undocumented function is bugging me. If you Long Press the AUTO button, text pops up saying "Awaiting Auto-Correction" and then nothing happens. All the buttons are locked and you must press the Reset hole to fix. Very odd.
K
Excellent but it took a long time
L
all ok good working

Looks great. Sometimes, it can't do automatic settings, and it freezes for a long time until discharge or reset. In general, for education purposes and sound measures, it is great. Excellent packaging.

Arrived in good condition. Just what I needed for the moment.
