Sonar View - Humminbird 917C Installation And Operation Manual

Sonar View

Sonar View presents a historical log of sonar returns. The most recent sonar
returns are charted on the right side of the window; as new information is
received, the older information is moved across the display to the left. A
scale with Upper and Lower Depth Range readouts appears along the right
edge of the Sonar View. The scale indicates the distance from the surface of
the water to a depth range sufficient to show the bottom. Depth Range is
automatically selected to keep the bottom visible on the display, although
you can adjust it manually as well (see Sonar X-Press™ Menu).
Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will
freeze the screen in the Sonar View and a cursor and cursor dialog box will
be displayed on the screen. The cursor can be positioned on the display
using the 4-WAY Cursor Control key to determine the depth of any sonar
return. The RTS® Window continues to update in Freeze Frame. In addition,
see the effects of menu setting changes with Instant Image Update.
Pressing EXIT will exit Freeze Frame and the display will start to scroll.

NOTE: If the Depth number is flashing, it means that the unit is having trouble
locating the bottom. This usually happens if the water is too deep, the transducer
is out of the water, the boat is moving too fast, or for any other reason that the
unit can't accurately receive continuous data.
