Weird noise from Speedlite 580EX
I recently bought a Speedlite 580EX and was just playing with it and noticed
that it emits a weird noise which sounds a bit like a beep every 4 seconds. Is this normal? I'm using a newly charged set of new 2500mAh NiMH batteries. Thanks, Mark |

Kibo informs me that "Mark Sztainbok" stated that:

If it's a typical electronic beep, it may be trying to tell you that you that the head is tilted off one of the stops. If it's very faint, it's probably the high voltage charging circuit. Try hitting the test button & see if it makes a difference. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

This is normal. Both of my 550EX flash units do this as well. As others have mentioned...be grateful that you can still hear this. I can too, and do not look forward to the day when I can't. -Not that this flash noise is particularly beautiful...but there are other sweet sounds many folks miss... |

The 420 does this too, and along the lines of the other part of this topic... I've always had sensitive hearing so I'd wear those foam earplugs to concerts, dance clubs, mowing the lawn, etc. My friends would tease me sometimes but after a while they just ignored it. Now we're all right around 40 and it's really telling the things I can still hear that they totally miss. Now if only I had taken that kind of care of my knees sigh.

If I can't hear it, it doesn't exist. Of course I may be a tree falling in the forest. I spent too many hours with unprotected hearing at the edge of a B-47 runway. Didn't really know the difference until early in the Personal Computer wave when I had a little program that swept the spectrum from 0 to 20,000 Hz, with a concurrent digital display of the frequency. It went "Rumble, oooo ooooo oooooo --- ". Cut off at 3800 Hz, like falling off a cliff. Just nothing there, even with great increases in volume. New use for the word, "Duh": "Rumble, oooo ooooo oooooo --- ". Guard your senses. -- Frank ess |

At least those B-47s were a worthy reason for hearing loss... ....It's better than blowing your life's hearing ability listening to the...um...music(???) young folks are into these days. -I must be getting old... Here's a question for ya, Frank... Did it ever occur to you that your computer SPEAKERS might not have been able to reproduce those high sounds? Most computer speakers are garbage... -Just a thought. (I don't know how high 3800 Hz is, so excuse my ignorance if 3800 is tiddly-winks on the pitch scale...) |
