  • Page 11 Part 1 Introduction Notes: 1. Values and functions given relate to the display; the heading sensor installed will determine the actual values and functions. 2. All headings and bearings may be referenced to either True or Magnetic North. If True North is selected, and True data is not directly available then the local magnetic variation may be entered (or received from a suitable Radio Navigator via NMEA).

  • Page 14 Operation Part 2 2.1.3 The Buttons The word below the button indicates the main function for that button. The HEADING button changes the current display mode to heading. The LOCK button acts in heading and locked course modes to re-lock the locked course and enable it to be changed.
  • Page 15 Part 2 Operation Notes: 1. The heading may be referenced to either Magnetic or True North. If only one type of data is available, and the other data is required then the local magnetic variation may be entered, or it may be read in from a Radio Navigator if one is fitted, and the correct NMEA message is transmitted by it.
  • Page 16 Operation Part 2 To Set Display Backlighting 1. Press the LOCK button and hold. The display backlighting will change from 0 to level 7, then level 6, then level 5, and so on to level 0. If the button is still held, the level will then increase back to 7 again.
  • Page 17 Part 2 Operation Demonstration Mode The Demonstration Mode allows the user to familiarize himself/herself with all the functions of the instrument with the device removed from the system. Demonstration software within the instrument produces realistic values for the display. A +12V power supply will be required to be connected as follows: 0V to the BLACK (far right) terminal.

  • Page 20 Installation Part 3 Depth sounders, etc. TWO metres from: Engines / electric motors Large masses of soft iron, e.g., keels THREE metres from: Radar magnetrons. It is possible to use a small hand-held magnetic compass to check the mounting location. Move the compass in a horizontal circle of approximately 30 cm (1 ft) radius around the desired mounting location.
  • Page 21 Part 3 Installation Installation of the COMPASS Display 1. Carefully position the self-adhesive template provided on the surface where the instrument is to be mounted. 2. Drill a small pilot hole first, and then check the location on the other side of the panel or bulkhead to confirm suitability.
  • Page 22 Installation Part 3 If the cable routing cannot be made with the Dataplug connector attached, then simply disconnect it from the cable. The cable may then be run through holes of down to 6 mm (0.25 ins.) diameter before reconnecting the Dataplug connector, making sure that the colours are correctly wired to the terminals.
  • Page 23 Part 3 Installation Figure 3.3 - Electrical Connections to the Display 6. Check that the instrument functions correctly. 7. Temporarily disconnect the Dataplug connectors and coat the terminals and wires with silicone grease or petroleum jelly. These products will not harm the instrument. 8.
  • Page 24 Installation Part 3 4. Release the transit screw on the sensor. This is found at the base of the sensor towards the rear. Unscrew the screw 10 full turns to allow full movement of the sensor assembly. If the sensor is being mounted externally then the screw should be removed and shortened by 10mm before refitting tightly.
