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.

Changing the Range

By default, the digital sounder automatically adjusts the display range,
selecting the shallowest range that keeps the bottom in the lower half of the
display window. Shift is disabled (the value is ignored) when auto-range is
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.
