580 EX beeping sound

Is it normal to have a very slight (almost inaudible) beeping sound every 6 seconds with a 580EX? .. this is the same sound that is made while the unit is recycling although at a very much lower volume.
Thanks,
Mike

Sorry .. my first search did not show anything but the next one did .. seems it's normal.

yes, mine does that all the time.

Yes, it is just topping up the capacitors to stay "at the ready".

With the new 580 mk. II this question won't be asked on a weekly basis.

yes! inaudible it says!

we'll wait and see but I just fail to believe I won't be able to hear the flash recycle. I kinda like the whine cause I can tell without looking that the flash is ready. Sure there are other lights and stuff to tell me in the viewfinder, but it's easier to just listen.
