Programming Via Escape Sequences

Tones 1 through 12 form a rough chromatic scale.
Good Read Beep Tone Example
To set the tone to a frequency of 687 Hz, send the following escape
sequence:
Esc – y 6 B
This function controls the volume of the speaker and toggles the speaker and
LEDs on/off.
Note: If an external speaker is connected, the internal speaker will be
disconnected.

Speaker/LED Control Example
To set the volume to low, send the following escape sequence:
Esc – y 34 C
This function causes the decoder to sound a tone at the selected pitch for
approximately 100 milliseconds. This tone can be used as an alert signal to a
remote decoder.
While a tone is being generated, another tone command can be accepted and
executed as soon as the first tone finishes. Only one tone command can be
buffered in this way. If two or more tone commands are sent before the initial
tone finishes, only the last is buffered.
