OPERATION
MENUS
This unit uses menus to guide you through the
unit’s functions and features. The menu key
accesses these features, allowing you to cus-
tomize the unit to your particular needs and
water conditions. All you have to do to leave one
menu and enter another is press the menu key
repeatedly. If you ever get lost in the menus,
simply press the PWR key. This clears the
menus from the screen.
Menus change depending on the mode the unit
is in. For example, if the automatic mode is
turned off, the sensitivity menu changes from “AUTO SENS” to “MAN
SENS.” Other messages may appear in menu boxes or new menus can
appear, again depending on previous selections.
AUTOMATIC
When the unit is first turned on, the automatic
feature is enabled. This feature automatically
adjusts the unit’s range and sensitivity ac-
cording to water conditions. It always keeps
the bottom depth displayed in the lower por-
tion of the screen.
To turn the automatic feature off, press the
menu key until the AUTO/MAN menu ap-
pears. Now press the down arrow key. This
highlights the letters “MAN.” The unit is now
in the manual mode. Wait a few seconds and
the menu will scroll off the screen’s left side.
Pressing the PWR key also clears it. To turn the automatic feature on
again, repeat the above steps, except this time press the up arrow key.
RANGE
You can’t adjust the range when the unit is in the automatic mode. It is
adjustable when the unit is in the manual mode, however. To do so, first
put the unit in the manual mode. Now press the PWR key to clear the
screen. Then press the menu key until the “RANGE SEL” menu appears
as shown at the top of the next page. The current range shows at the
bottom of the menu. In this case, the range is 60 feet. Now press the up
arrow key to decrease the range, the down arrow key increases the range.
