Selecting a Display Mode

The CSH-23F/24F provides three display modes: normal sonar picture, echo sounder (E/S) combination, and history display combination. Those modes may be selected with the NORM, E/ S and HIST keys.

Table 2-1 Display mode description

Mode

NORMAL

E/S

Description

The sonar picture appears over the entire screen. This mode is useful for detecting and tracking fish schools.

The default display area is 1.3 times the range, but it can be changed to

1.6times the range on "EXT KP/TM DSP" in the SYSTEM menu. Navigation information can be displayed in the text window at

the screen bottom by turning on

"DATA DISPLAY" in the USER menu.

Normal scanning picture appears on the upper 5/8 of the screen and the signal fed from the echo sounder on the lower 3/8. This mode is suitable for judging fish school concentration.

When two echo sounders are connected, each pressing of the E/S key alternately selects echo sounder 1 or echo sounder 2.

Note that a net recorder can be connected as echo sounder 2; select it on the "ES" sub menu in the INIT SET/TEST menu.

Normal scanning sonar picture appears on the upper 5/8 of the screen and the history display on the lower 3/8. Three types of history displays are available: Audio, Port/Starboard and Horizontal Slice. You can select which one to display on the USER menu.
