Selecting the Power Setting

The DSM250 defaults to manual scroll adjustment at full speed
(100%). Use the trackpad to decrease the scroll speed in 10%
increments down to 0% (pause). Unlike automatic adjustment,
manual scroll speed is not related to boat speed over the bottom.
Alternatively you can have the sounder automatically adjust the
scroll speed, based on boat speed. If you select automatic adjust-
ment, the scroll speed is related to boat speed as follows:
• Less than, or equal to 0.5 kts, scroll speed is constant at 10%
• Between 0.5–15 kts, scroll speed varies linearly with boat speed
• Greater than 15 kts, scroll speed is constant at 100%
You can also pause the display in either manual or automatic
mode. The depth indication continues to be updated.
To change the scroll speed:
1. Press MENU, then press the SCROLL SPEED soft key.
2. If necessary, press the SCROLL AUTO MAN soft key to toggle the
setting between AUTO and MAN.
3. For manual adjustment, use the trackpad to change the scroll
speed in 10% increments from 0 to 100%. You can press and hold
the trackpad to change the value more rapidly.
4. Press ENTER to return to the Menu soft keys, then ENTER again to
return to the default display.
To pause the scrolling display:
1. Press MENU, then press the SCROLL SPEED soft key.
2. Press the PAUSE soft key. The display stops scrolling and the key is
relabeled RESUME.
3. To resume scrolling, press the RESUME soft key. The key is rela-
beled PAUSE.
4. Press ENTER to return to the Menu soft keys, then ENTER again to
return to the default display.
The POWER soft key provides adjustment of the transducer signal.
When AUTO is selected (default), the sounder automatically deter-
mines the optimal 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).
