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 selected for meters, feet, fathoms, passi/braza or Hiro (Japanese) with UNIT on the SYSTEM SETTING 1 menu. For details see page 5-10.

Note 2: Ranges may be freely preset as desired. For details see page 5-14.
