The horn function is useful while underway to alert another vessel
of your intention. A short blast is a press of the PTT for 1 second
and a prolonged blast is a press of the PTT for 2 seconds:
- one short blast to mean "I am altering my course to starboard";
- two short blasts to mean "I am altering my course to port";
- three short blasts to mean "I am operating astern propulsion."
3. Rotate the PA knob to adjust the AF output level. The AF output level

4. When the Fog signal or Siren and Horn signals are not transmitted to
the PA horn, turn the LISTEN/PWR knob to increase or decrease the
listen back volume from the PA horn.
5. Press the PA button to disable the Automatic Signaling feature.
