At the top left of the display you will find the Adjustment Bar and
a variety of user-selectable information including Depth, Battery Voltage,
Water Temperature, and Speed Over Water. To provide data on Speed Over
Water, the Fishfinder 100 Blue requires an additional speed sensor.
The Depth Scale and the Flasher are displayed from top to bottom
along the right side of the display. Messages and Alarm Icons are displayed
along the bottom.
The Fishfinder 100 Blue has three levels of display backlighting: Off,
Low and High. The backlight is activated by momentarily pressing the
Power key. To change the backlight level, press the Power key repeatedly.
If the unit is unable to track the bottom for any reason,
the digits in the depth window will fl ash on and off to
alert the user that the unit is not tracking the bottom.
