400-30;10;(.25+.25) means:
400 Hz, -30 dBm minimum level, plays 10 seconds, cadence is 0.25 seconds on, 0.25 seconds off.
The only parameters that need to be customized are frequency, on time and off time.
Opening the recording in an audio editor (Audacity is a good free one), you can easily measure on and off time. Most editors can meaure frequency and/or show a spectral plot. If yours can't, or if the signal is noisy, just zoom in and count the number of cycles in a short interval, e.g. 20 or 50 milliseconds.
