3.3 Adjusting the Display
This section describes the controls you can use to change how sounder data is
displayed on the A65 in Fishfinder mode.
Range
The DSM automatically adjusts the display to show the shallowest required range.
Alternatively, you can select to range in/out on the image (up to the maximum
depth displayed on the scrolling bottom and A-Scope images).
To range in/out on an image:
1. Press the RANGE key. The RANGE soft keys appear.
2. Press the down arrow on the RANGE key to increase displayed range (deeper)
and press the up arrow key to decrease it (shallower). The RANGE field
switches to MAN.
3. To return to the automatic range adjustment, toggle the RANGE soft key to
AUTO.
The default range setting is AUTO. This setting is reset at power-up.
Range Shift
The DSM automatically adjusts the display to keep the bottom in the lower half of
the display window. Alternatively, you can shift the image within the current
range.
To shift the image:
1. Press the RANGE key. Soft keys appear, with SHIFT grayed out.
2. Toggle the RANGE soft key to MAN. The SHIFT soft key is no longer grayed out.
3. Press SHIFT. This soft key is highlighted.
4. Use the rotary control to adjust the shift up or down. The value of the shift is
displayed on the soft key.
5. To return to the standard fishfinder image, toggle the RANGE soft key to
AUTO.
The default range shift setting is 0. This setting is reset at power-up.
