KEYBOARD BASICS
The unit sounds a tone when you
press any key. This tells you the
unit has accepted a command.
PWR/CLEAR
Use this key to turn the unit on and
off. It also clears menu selections
and the menus from the screen.
Note! To turn the unit off, press and
HOLD the PWR/CLEAR down. A
countdown from 3 seconds ap-
pears on the screen when you hold the PWR key down for more than a
couple of seconds. When the countdown reaches zero, the unit shuts off.
This prevents you from accidentally turning the unit off.
MENU FWD/MENU REV
This sonar has many features that are accessed with these keys. To scroll
forward through the menus, press the MENU FWD key repeatedly. To go
backwards through the menus, press the MENU REV key repeatedly.
UP and DOWN ARROWS
Use these keys to adjust virtually every feature and function on the unit.
The up arrow key also stops the chart when no menus are displayed.
DISPLAY - General
The lights flash for about ten seconds when the unit is turned on. Two
menus appear, one after the other. The menus are the lights (BACK
LIGHT) and feet-meter selection (FEET/METER). To turn the lights on,
press the up arrow key while the backlight menu is showing. To switch from
feet to meters, press the down arrow key
when the proper menu appears. The menus
disappear after a few seconds. If you don’t
want to wait, press the PWR/CLEAR key to
clear the menus from the screen.
When the unit is first turned on, the display
appears similar to the one at right. The unit is
in the automatic mode. The depth range
displays on the upper left side of the screen.
In the example at right, the range is from 0 to
60 feet and the bottom depth is 48.6 feet.
