Erasing Tracks

There are two methods to erase tracks: by color and by line type. Be absolutely
sure you want to erase track; erased track cannot be restored.
Note 1: Files set to "YES" on the DISPLAY DATA FROM MEMORY CARD menu
cannot be erased. (See paragraph 10.2.3.)
Also, files set to "YES" on the DISPLAY DATA FROM INTERNAL
MEMORY menu cannot be erased. (See paragraph 10.4.2.)
Note 2: If own track is being automatically colored according to depth or water
temperature, and the color in use just before selecting "TRACKS BY
TEMP" or "TRACKS BY DEPTH" is chosen for erasure, all depth- (or
water temperature-) colored track from that point to the time of erasure
will also be erased. (See paragraph 3.3.1.)
