Selecting the Power Setting
The
POWER
soft key provides adjustment of the transducer signal. When
AUTO
is selected (default), the sounder automatically determines the power setting
based on the current depth, speed, and (bottom) signal strength. When
AUTO
is selected the current automatic power setting is indicated in the top status
line by an
L
(low) or
H
(high)
.
If, however, you wish to manually adjust the power to suit current conditions,
you can select either
LO
or
HI
power.
LO
power (100 W) is normally used in
depth ranges less than 8 ft (2.4 m) and
HI
power (600 or 1000 W, depending on
your transducer) is typically selected for depths greater than 12 ft (3.7 m).
The power setting is retained when the unit is powered off.

selected.
Alternatively, the
RANGE
key lets you select the maximum depth displayed
on the scrolling bottom and A-Scope displays. You can also set the shift value
to move the image window up or down within the current range.
