How to set the track plotting interval
In drawing the track, the position of your ship is stored into the memory of this equip-
ment at an interval of time or distance. A shorter interval provides better reconstruction
of the track, but the storage time of the track is reduced. When the track memory be-
comes full, the oldest track is erased to make room for the latest.
