Displays; Vertical - Interphase iScan V90 Operation Manual

Displays

The iScan V90 has three basic display modes which can be
accessed directly by pressing one of the four buttons with the
display's name. The following paragraphs give a brief
description of each of these display modes. More detailed
information on how to interpret and make adjustments in these
displays can be found in pages 29 to 30 Interpreting your
iScan V90's Display.
Vertical Scan
Press the button labeled "VERT" to view a full screen forward
looking vertical scan display. In this mode, the Iscan V90 scans
a 90 degree sector from the surface ahead to the bottom directly
below. The resulting display shows the bottom and objects
directly in front of the vessel.
The display should look similar to the unit shown at right. The
boat icon at the top left of the display represents the position of
the vessel. The horizontal line with the scale across the top of
the display represents the surface of the water and the vertical
scale represents the depth below the vessel.
The current depth directly below the boat is shown at the top
left of the display - just in front of the boat icon.
The current forward range is shown by the digital number at the
far top right of the display. This number will change as
different ranges are selected. Adjust RANGE/GAIN (see page
25) to optimize the picture.
The Depth Bar on the left side provides a visual indication of
the depth directly beneath the boat. Adjust in DOWN Mode.
