6.4 Automatic Signaling
Automatic Signaling is typically transmitted through the PA horn, but the
VLH-3000 can also send these signals to the intercom speaker(s).
1. Select the PA horn to be used by pressing the FWD , BOTH , or AFT
button.
2. Press the one of the AUTOMATIC SIGNALING button to send the de-
sired signal to the selected PA horn:
Fog Horn Signaling
UNWY (Underway): Sends one 5-second blasts ever 2 minutes.
STOP : Sends two 5-second blasts (separated by 2 sec-
onds) ever 2 minutes.
SAIL : Sends one 5-second blasts followed by two 1-sec-
ond blasts (separated by 2 seconds) ever 2 min-
utes.
TOW : Sends one 5-second blasts followed by three 1-sec-
ond blasts (separated by 2 seconds) ever 2 min-
utes.
ANCH (Anchor): Sends one 5-second rings every 1 minute.
AGND (Aground): Sends one 11-second rings every 1 minute.
Passing signals
SIREN : Sends a varying pitch (yelping) tone while pressing
the microphone
PTT button.
HORN : Sends a passing signal while pressing the micro-
phone
PTT button.
NOTE
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 can
be set from 0 to 30 watts.
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.
