Manual Mode turns off the automatic bottom
tracking leaving control of the depth range to the
user. Both the upper and lower depth ranges can be adjusted to show the
bottom in great detail or any other desired depth. When first switched to
manual mode, the 160 defaults to the current automatic depth range;
however, after the manual depth ranges have been set, the 160 uses the
new settings until it is powered off.
Manual Mode works best in areas of relatively flat bottom or if you are
trolling slowly. It is also ideal for displaying a small area of the overall depth
range in great detail if you are looking for fish at a specific depth.
To manually adjust the depth ranges follow these steps:
1. Make sure the 160 is operating in Manual Mode.
2. Push the Range Knob. An adjustment indicator appears at the location
of the lower Depth Range indicating it is ready for adjustment.
USING THE 160
Note: Pushing the R
toggles between the upper and
lower zoom preview bar adjust-
ment. If the lower zoom preview
bar is to be adjusted, push the
±
Range
Knob until it is selected.
3. Rotate the Range Knob to adjust the
zoom preview bar. Moving the zoom
preview bars closer together increases the
display resolution in the zoomed window;
moving them further apart decreases display
resolution, but allows more area around the
bottom to be viewed.
