Figure 5-6: Effect of the Scroll Speed
The fishfinder 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 adjustment, 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

2. If necessary, press the

between AUTO and MAN .
3. For manual adjustment, use the trackpad to increase the scroll speed. You
can press and hold the trackpad to change the value more rapidly.
4. Press
ENTER

again to return to
the default display.
