Beeping frequency in Hz. Default value assigned is 0.
The frequency range supported and the behavior when values outside of the range was provided are depended on the actual hardware used for the notification device.

If a frequency outside this range is specified, the RS6000 will change the frequency to the closest supported frequency.
