+# These are the helper functions for the kma20 audio panel
+# Maintainer: Thorsten Brehm (brehmt at gmail dot com)
+#
+# Usage:
+# just create one instance of kma20 class for each kma20 panel
+# you have in your aircraft:
+# kma20.new(0);
+#
+# KMA20 audio panel properties:
+# root: /instrumentation/kma20
+#    knob: microphone/radio selector (com1/2)
+#    auto: selects COM1/2 based on microphone selector
+#    com1: enable/disable COM1 audio (e.g. for ATIS)
+#    com2: enable/disable COM2 audio (e.g. for ATIS)
+#    nav1: enable/disable NAV1 station identifier
+#    nav2: enable/disable NAV2 station identifier
+#    adf:  enable/disable ADF station identifier
+#    dme:  enable/disable DME station identifier
+#    mkr:  enable/disable marker beacon audio
+#    sens: beacon receiver sensitivity
