TRACK
2.1 Stopping Track Recording
When your ship is at anchor or returning to port you probably will
not need to record the track. You can stop recording the track, to
conserve the track memory, by activating the “hold” function. The
track is displayed but not recorded, thereby conserving the track
memory.
Press the [PLOT INTVL] key to display HOLD. The indications
“HOLD” and “H” appear on the display. The track is traced on the
display but is not stored. To resume plotting press the key again.
“HOLD” and “H” disappear.
