Is there a way to calibrate to viewfinder? I just got my unit new from Harvey. But when I try to view through the viewfinder, i cant make up the text nor image displayed, too blurry to see. There seems to be no info about it from the manual. I should have checked this part thoroughly before i purchased it. 
it was just on the left side hidden when you pull out the viewfinder. And coz it was all black so I didn't immediately noticed. silly me
