[. . . ] Select the required LCD contrast level, either 1 or 2, by pressing both buttons together. Return to the main display by pressing the HEADING button three times to select the Calibration Mode End Screen, and then pressing both buttons together. Page 25 Setting-Up 4. 6 True / Magnetic Headings and Bearings Selection Part 4 The displayed heading and bearings may be set to reference either Magnetic or True North. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. 2. Press the LOCK push-button three times until the LCD indicates the current selection as (a distorted) 'MAG' (or 'truE'). Select the required heading reference, either Magnetic or True, by pressing both buttons together. Return to the main display by pressing the HEADING push-button four times to select the Calibration Mode End Screen, and then pressing both buttons together. 4. 7 Magnetic Variation Entry As a default the Magnetic Variation compensation on the COMPASS is turned Off, and it will only read messages that contain the correct data, either Magnetic or True. This is the `safest' setting because an incorrect Variation setting will not give false or erratic data. However in some instances some of the displays may not be available because the data is not in the correct format. For instance, True Headings may be required, while the heading sensor is a fluxgate compass giving Magnetic data, or the Waypoint Display may not be available because the heading is Magnetic, but the only Waypoint Bearings available are True. Therefore the COMPASS can have the local magnetic variation entered so that it can change incoming headings or bearings from Magnetic to True, or vice versa. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. Press the LOCK button four times until the LCD indicates ' VAr?' Press both buttons together to start to set the variation value, the current value will be shown flashing. The variation is turned off by setting it to between -1° and +1° Increase the variation value (or turn it on at +1° if it is off) using the LOCK button. 4. 5. Decrease the variation value (or turn it on at -1° if it is off) using the HEADING button. Page 26 Part 4 6. Press both buttons together to save the variation value. 7. Setting-Up Return to the main display by pressing the HEADING push-button five times to select the Calibration Mode End Screen, and then pressing both buttons together. 4. 8 Compass Auto-Deviation Compensation The Calibration process must be performed after installation of the system, after any movement, additions, or removals of metal objects from the vicinity of the sensor, and also if the vessel is moved to a latitude of more than 20° from where the last calibration was carried out. Calibration of the Dataline Heading sensor is controlled by the COMPASS display, whereas calibration of the Robertson RFC250 Heading sensor is done automatically by the sensor. 4. 8. 1 Compass Auto-Deviation Compensation - With the Dataline Heading Sensor In order to compensate the Dataline Heading sensor first select the auto deviation compensation screen in the Calibration mode, and then command the heading sensor to perform its Automatic Deviation Correction Calculation. When the sensor has started the process the vessel should be slowly steered in a number of circles until the sensor signals that the process has been finished. This will normally take up to four rotations, and is best performed in good conditions, with a calm sea. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. [. . . ] Check that the location of the sensor is suitable, if not then resite it. The location of the sensor is unsuitable. For Standalone Displays Condition The LCD display is blank and the pointer does not move. Check the power supply wiring. Other Faults Condition The external alarm does not sound. Probable Cause The alarm is not turned on, or the values are not as desired. Action Check that the desired alarm is turned on and has the correct value. [. . . ]
