2.4 Smoothing
Even when the vessel is sailing in a straight line the track shown on the display
looks irregular. This is due to signal variation of the external navaid. You can
compensate for this irregularity with smoothing.
A smoothing factor between 1 and 9 is available. OFF provides no smoothing. In
most cases a smoothing setting between 1 and 5 is satisfactory.
1. Press the [NAV MENU] and [5] keys.
2. Press the [8] key to choose smoothing factor.
3. Press the [ENTER] key.
4. Press the [NAV MENU] key to close the menu.
