Bad Tones / Good Tones on HP41CX

Posted by Thomas (CH) on 13 Jan 2005, 12:47 p.m.

Here is a complete list of good tones as tested on my HP41CX:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 15, 17, 19, 23, 25, 29, 34, 40, 42, 46, 48, 51, 52, 55, 80, 85, 86, 89, 105, 106, 109, 117, 119.

These are the bad tones, which leave the piezo buzzer in a noisy state:

10, 11, 12, 13, 14, 16, 18, 20, 21, 22, 24, 26, 27, 28, 30, 31, 32, 33, 35, 36, 37, 38, 39, 41, 43, 44, 45, 47, 49, 50, 53, 54, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 81, 82, 83, 84, 87, 88, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 107, 108, 110, 111, 112, 113, 114, 115, 116, 118, 120, 121, 122, 123, 124, 125, 126, 127.
