Normally the range is set so that the bottom is traced at the lower part of the screen (like an
echo sounder). Each time the RANGE control is operated the newly selected range briefly
appears in large characters at the screen top. Range is always displayed at the right-hand
corner of the screen.
Note 1: Unit of range measurement may be chosen from among meters, feet, fathoms,
passi/braza or Hiro (Japanese) with UNIT on the SYSTEM SETTING 1 menu. For details
see page 5-11.
Note 2: Ranges may be freely preset as desired. For details see page 5-14.
