Usually I stick to the Russian forum but I recently had the urge to get my hands on one of those Casios with the remote control function. Got a CMD-40 on ebay and it works, kind of. I can set it, cycle through the functions and turn the beeper on and off but the calculator buttons don't work. Does anyone have any idea what might be causing this? It works fine as a watch but it'd be nice to get it all working.
