After placing a pre-order back in May, and after several shipping delay extensions, my CT-S400 finally arrived last week. I bought it as my "portable" keyboard, since my 81-note PX-S3000 is a little too bulky for my tastes to take on the road.
After playing around with it for a week, I finally got around to trying it out with batteries -- one of the important features I bought it for. But unfortunately I can't seem to get the AA's to fit. I've tried putting them in top-first, bottom-first, and sliding in side-ways, tried several different brands, and they just won't fit past the plastic fittings surrounding the metal contacts.
Before I pull out a file and void my warranty by filing down the offending plastic, I wanted to see if anyone else has had problems with the battery case with any model CT-S series.
Maybe I just got lucky with a batch having a manufacturing defect...
