To adjust the Sensitivity:
1. Highlight Sensitivity on the Sonar X-Press
TM
Menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Sensitivity setting. (Low = 1, High = 20, Default = 10)
Upper Range
(Advanced: Sonar, Split Sonar and Big Digits Views Only)
Upper Range sets the shallowest depth range that will be displayed on the Sonar,
Split Sonar and Big Digits Views. The Upper Range menu choice is available when
User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be
accessed from the Sonar, Split Sonar and Big Digits Views. Upper Range is often used
with Lower Range.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower
Range regardless of the manual settings entered.
To adjust the Upper Range:
1. Make sure you are in Advanced Mode, then highlight Upper Range on the
Sonar X-Press
TM
Menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the
Upper Range setting. (0 to 790/990/1490 feet or 0 to 257/327/497 meters
[International Models Only], Default = 0)
NOTE: Settings are dependent on the depth capability of your particular Fishing System model.
For example, if you are only interested in the area between 20 and 50 feet deep,
you should set the Upper Depth Range to 20 and the Lower Depth Range to 50.
The Sonar View will then show the 30 foot area between 20 and 50, and will not
show the surface or the bottom (assuming the bottom is deeper than 50 feet), and
will show greater detail for that area between 20 and 50 feet.

Sonar X-Press
TM
Menu
The Sonar X-Press
TM
Menu provides access to the
settings most frequently-used. Press the MENU key
once while in any of the Sonar Views to access the
Sonar X-Press
TM
Menu.
NOTE: Upper Range only appears in Advanced User
Mode when in Sonar, Split Sonar or Big Digits View.
NOTE: Zoom Level only appears in Sonar Zoom View.
Sensitivity
Sensitivity controls how much detail is shown on the
display. Increasing the sensitivity shows more sonar returns from small baitfish and
suspended debris in the water; however, the display may become too cluttered.
When operating in very clear water or greater depths, increased sensitivity shows
weaker returns that may be of interest. Decreasing the sensitivity eliminates the
clutter from the display that is sometimes present in murky or muddy water. If
Sensitivity is adjusted too low, the display may not show many sonar returns that
could be fish.
