RANGE - Automatic
When turned on for the first time, the
unit automatically places the bottom
signal in the lower half of the screen.
This is called Auto Ranging and is part
of the automatic function. Typically,
the range cannot be changed manu-
ally while the unit is in automatic, as
shown at right. However, depending
upon the bottom depth and the current
range, you can change the range to a
different depth. In the example screen
shown below, the bottom depth has
descended to a point where you can
change the range to 150 feet. To do this, simply press the right arrow key
while the Auto Range menu is displayed. When you're finished with this
menu, press the EXIT key to erase it.
RANGE - Manual
You have complete control over the
range when the sonar is in the manual
mode.
To change the range, first make cer-
tain the unit is in the manual mode.
Next, press the MENU key and the up
or down arrow keys until the range
menu appears as shown at right. Press
the left or right arrow keys to decrease
or increase the range. The available
ranges are 0-5, 10, 20, 30, 40, 60, 100,
150, 200, 300, 500, 800, and 1000 feet. After the desired range is
displayed, press the EXIT key to erase the range menu.
NOTE: The depth capability depends on the frequency selection, trans-
ducer installation, water and bottom conditions, and other factors.
