SPEED CALIB.: If the speed sensor-generated speed indication is wrong, you can correct it here, when “Own” is selected as speed source. For example, if the speed indication is 10% lower than actual speed, enter +10. The setting range is –50% to +50%.

BASIC RANGE 1 - BASIC RANGE 8: Set range of each of the eight basic ranges. (Selectable range: 7 to 1500 ft)

Note 1: All default basic ranges are restored whenever the depth unit is changed. Therefore, change the depth unit before changing the basic ranges.

Note 2: A range may not be lower than the range preceding it. For example, if basic range 3 is 60 feet, basic range 4 must be greater than 60 feet.

ZOOM RANGE: Choose the range to zoom in the marker-zoom and bottom-zoom modes. You may choose a range between 7 and 150 feet (2 and 50 meters).

B/L RANGE: The expansion width for the bottom-lock display can be chosen from 10 to 30 feet (3 and 10 meters).

ZOOM MARKER: The zoom marker appears in the normal, bottom marker and bottom zoom displays and marks the area which is expanded in the bottom marker and bottom zoom pictures. You can turn the marker on or off as desired.
