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
