Hitachi Rice Cooker Button ID Help

I just bought a Hitachi rice cooker at a thrift store. The problem I'm
having is that all the labels are in Japanese so I have no idea what
buttons do which
function.  There is a row of three buttons: gray, white, and white
with a light.  There are two triangles to adjust the warming times?
and an orange button that seems to function as a stop/clear button. 
That just leaves the red display and the red and green
lights(on/off?)next to the display.  Can you identify the buttons and
give me a general idea of how this cooker operates?  Thanks for your
time!  Steve
