Shifting the depth range
The normal image consists of two types, the fixed shift and auto shift. If you select the fixed shift, the
image is displayed on the screen within the extent between the predetermined depth (
Shift position
)
and the also predetermined range. In the auto shift, on the other hand, sea bottom is constantly on the
lower part of the screen and if water depth changes, the image is automatically shifted to the direction
of depth change.

Shifting the depth range
Pressing the

employed, pressing the key once increases or decreases the value by 1 meter). When you move into
the fixed shift from the auto shift, however, shifting starts from the value being set in the auto shift
mode.
