RANGE - Automatic
When turned on for the first time, the LMS-350A automatically places the
bottom signal in the lower half of the screen. This is called Auto Ranging
and is part of the automatic function. The range cannot be changed
manually while the unit is in automatic.
RANGE - Manual
The LMS-350A gives you control over the range when it’s in the manual
mode. There are two different methods used to change the range. The first
way changes only the lower limit by pressing the arrow keys. On the
screen shown below, the lower limit is 60 feet. The upper limit is zero. The
second method lets you change
both the upper and lower lim-
its. This let's you create a
"zoom" window down to five
feet in virtually any combina-
tion of upper and lower limits.
For example, a range with a 15
foot upper limit and a 45 foot
lower limit creates a 30 foot
zoom window. If the original
range was zero to sixty feet,
then this created a 2X zoom.
To change the range, first make certain the LMS-350A is in the manual
mode. Next, press the RANGE key. The range adjustment menu appears
on the  right side of the display. To change only the lower limit, simply press
the up or down 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,
1000, 1500, 2000, 3000, and 5000 feet. After the desired range is
displayed, press the CLEAR key to erase the range menu.
NOTE: The maximum depth
capability of the LMS-350A de-
pends on the transducer instal-
lation, water and bottom condi-
tions, and other factors. The
performance of the LMS-350A
will vary from day-to-day be-
cause of changing conditions.
