Always 2 tones are assigned to each key on the dialpad.The length of the tone and the pause between the tones can be set from 35ms to 1500ms. A total of 36 marco’s also can be used to play phone numbers, ham radio auto patch numbers, amateur radio echolink id’s any many more.The 36 macro’s can be saved to the phones/tablets memory. This way a unlimited amount of macros can be used. The tone length and the pause between the tones can be adjusted.
