Sanyo ICC-810 - HOLD?

From: Katie

I recently got a Sanyo ICC-810, it's a wonderfully small and heavy early electronic calculator nearly identical to the Sanyo ICC-807D but with a HOLD light and a "H" key. My question is how is the "H" key suppose to work? I assume that it's some form of memory, but I'm not sure nor am I sure that it's working correctly on my 810. Thanks, Katie
