I see an M2 indicator in the upper left corner of the screen, yet I cannot find a way to turn it off. I'd appreciate any ideas.
Step 2 take a sharping stone and make the end really sharp like a needle.
Step 3 take out you calculator.
Step 4 move your hand away from the screen.
Step 5 violantely stap the sharp object into the M2 corner.
This will elimanate the display of this object in the left-corner.
(I will delete this totally useless post after you read it).
