 		|Error detected during sensor calibration.
 		|====
 
+		Here's a summary of all of the Pad and Idle mode
+		indications. In Idle mode, you'll hear one of these
+		just once after the two short dits indicating idle
+		mode. In Pad mode, after the dit dah dah dit
+		indicating Pad mode, you'll hear these once every five
+		seconds.

+		For devices with a radio transmitter, in addition to
+		the digital and APRS telemetry signals, you can also
+		receive audio tones with a standard amateur
+		70cm FM receiver. While on the pad, you will hear
+		igniter status once every five seconds.

+
+		During ascent, the tones will be muted to allow the
+		telemetry data to consume the full radio bandwidth.
+
+		During descent and after landing, a ½ second tone will
+		be transmitted every five seconds. This can be used to
+		find the rocket using RDF techniques when the signal
+		is too weak to receive GPS information via telemetry
+		or APRS.
