automatic True Motion Reset OFF. When TM Reset is OFF you have on upper right hand part of the display either
indication Ship out of dsp or TM RESET OFF depending of the view.
You can enter numerical values for center of the chart display. Press DISPLAY MODE push button and select Set
Center from the menu, a Chart Center dialog box appears:
Enter desired values for center of chart display.
If you want immediately back to your own ship position, push TM/CU RESET.
ZOOM IN and ZOOM OUT are used to change scale of chart. If TM reset is active, ZOOMI IN and ZOOM OUT
keep the relative position of the own ship respect to the display. If TM Reset is OFF, ZOOM IN and ZOOM OUT
keep the relative position pointed by cursor respect to the display.
The system has a logical way to automatically select next larger or smaller scale. The system has an indication of
LARGER SCALE DATA EXISTS, if there exist a chart with larger compilation scale available at your current
