Upper And Lower Limits - Lowrance GlobalMap 2000 Installation And Operation Instructions Manual

To change the range, simply press the up arrow key to decrease it or the
down arrow key to increase it. If the unit is in automatic, it may change the
range immediately to keep the bottom on the screen.
Another way to adjust the range
is through the menus. Press
the MENU key, then press the
key adjacent to the "Sonar Con-
trols ..." menu. A screen similar
to the one at right appears.
Now press the up or down ar-
row keys to decrease or in-
crease the range. When you're
finished with the adjustment,
press the CLR key to erase the
menus.
The available ranges available with the arrow keys are: 0 - 5, 10, 20, 30,
40, 60, 100, 150, 200, 300, 500, 800, 1000, 1500, 2000, 3000, and 5000
feet; 0 - 3, 5, 10, 12, 15, 20, 30, 40, 60, 100, 150, 200, 300, 400, 600, 1000,
and 1500 meters; 0 - 1.2, 2, 5, 7, 10, 15, 20, 30, 40, 60, 80, 100, 150, 200,
300, 500, and 800 fathoms.

UPPER AND LOWER LIMITS

When the manual mode is on, the range's upper and lower limits can be
changed in one foot increments provided there is at least ten feet between
them. For example, an upper limit of 31 feet and a lower limit of 41 feet has
a ten foot range. This feature gives you unparalleled control, allowing you
to see virtually any segment of the underwater world. Using the upper and
lower limits makes zooming in on structure, fish, and other targets easy.
To use the upper and lower
limits, first make certain the unit
is in the manual mode. Now
press the MENU key, then
press the key next to the "So-
nar Controls ..." label. Finally,
press the key next to the "More
..." label at the bottom of the
menu. A screen similar to the
one at right appears.
