1.8 How to Shift the Display Range
When used together, the basic range and range shifting functions allow you to select
the depth you can see on the screen. The basic range can be thought of as providing
a "window" into the water column and range shifting as moving the "window" to the
desired depth.
Note 1: This function is not available when auto range or auto shift is active.
Note 2: The seabed echo may be lost if the shift is at a greater value than the seabed
depth.
To shift the display range, do as follows:
1. Display the header if it is not "pinned". If the header is displayed, go to step 2.
2. Click the [SHIFT] indication on the header. The indication is now highlighted in a
green color.
3. Scroll to change the amount of shift used. The current shift setting appears in on
the header.
Window can be
shifted up and
down to select
starting depth.
