HP41CV Keys Beep Message #1 Posted by Jon Bakker on 12 Aug 2002, 2:47 p.m. My HP41CV beeps with every key stroke. Does anyone know what I can do to stop this annoying beep?

Re: HP41CV Keys Beep Message #2 Posted by Philip Reagan on 12 Aug 2002, 3:11 p.m., in response to message #1 by Jon Bakker Yes. Either press the BEEP key (which is a shifted function on the keyboard) or do XEQ [ALPHA]TONE[ALPHA]9. This problem can occur due to a bug in most systems. If you have the TIME module it probably beeps every second as well.

Re: HP41CV Keys Beep Message #3 Posted by Jon Bakker on 12 Aug 2002, 4:42 p.m., in response to message #2 by Philip Reagan Thanks. It worked exactly as you said. Now why didn't the manual tell me this??

Re: HP41CV Keys Beep Message #4 Posted by Philip Reagan on 12 Aug 2002, 6:17 p.m., in response to message #3 by Jon Bakker Well, because HP didn't intend for that to happen. It's a bug. The bug is documented in a book called "Extending your HP41" and probably other places.

Re: HP41CV Keys Beep Message #5 Posted by Raymond Hellstern on 13 Aug 2002, 2:51 a.m., in response to message #4 by Philip Reagan I think it happens when there's some 'dirt' left in the tone register. Raymond

Many times, this happens when changing batteries Message #6 Posted by Gene on 13 Aug 2002, 7:51 a.m., in response to message #5 by Raymond Hellstern If you take the battery pack out or let it slowly slip out and then put it back, this can sometimes happen too.

Turning on HP41CV Keys to Beep Message #7 Posted by Matt Kernal (US) on 13 Aug 2002, 11:16 a.m., in response to message #4 by Philip Reagan I don't have my copy handy, but what was/is the three-button key-press that turns on the keys to beep? Thanks, Matt

Re: Turning on HP41CV Keys to Beep Message #8 Posted by Philip Reagan on 13 Aug 2002, 12:29 p.m., in response to message #7 by Matt Kernal (US) I've gotten it to occur on my CX which implements the Reset option (ENTER+ON). If you execute BEEP and then press ENTER+ON trying to time that reset during a BEEP, the "problem" will occur. It may take several times to get it to happen. Be sure to press the ENTER key first and then ON or the unit will turn off. Try to time the pressing of the ON key with the occurance of a BEEP.

Re: Turning on HP41CV Keys to Beep Message #9 Posted by Matt Kernal (US) on 15 Aug 2002, 11:22 a.m., in response to message #8 by Philip Reagan Thanks for your detailed description... I remembered the timing of pressing the keys was important. In 1987, we used to play this beeping trick on unsuspecting co-workers before they arrived at work. There was also the small program to turn the 41 off as soon as it was turned on. Fun memories. Thanks again, Matt
