Factory-Fixed-Frequency Beeps
Forty-eight (48) beeps have been defined in frequency but have variable
duration. These beeps are programmed with the character codes 00–47 and
cover almost four octaves from 262Hz to 3951Hz. It is best to avoid beeps
below 300Hz and above 3000Hz, since most radio systems are designed for
300–3000Hz response.
The following table shows the Factory-Fixed Frequency Beeps:
This table includes associated note values for each frequency. However, these
note values are simply intended as a guide to the pitch of each beep and
should not be construed as musical in nature.
