Upper Range
(Advanced:Sonar,SplitSonar,BigDigitsandCircularFlasherViewsonly)
Upper Range sets the shallowest depth range that will be displayed on the Sonar,
Split Sonar, Big Digits and Circular Flasher 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, Big Digits and Circular Flasher
views. Upper Range is often used with Lower Range.
NOTE: A minimum distance of 10feet will be maintained between the Upper and Lower
Range regardless ofthe manual settingsentered.
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 orRIGHT 4-WAYCursor Control keysto increaseor decreasethe
Upper Range setting.(0 to 990feet or0 to327 meters[International Models
Only], Default = 0)
For example, if youare only interested inthe area between 20 and50
feet deep, you should set the Upper Depth Rangeto 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.
