1 From a sonar view, select > Sonar Setup > Scroll
Speed.
2 Select an option:
• To adjust the scroll speed automatically using speed-overground, select Auto.
The Auto setting selects a scroll rate to match the boat
speed, so targets in the water are drawn with the correct
aspect ratio and appear less distorted. When viewing
Garmin ClearVü or SideVü sonar views, it is recommend
to use the Auto setting.
• To use a very fast scroll speed, select Ultrascroll®
.
The Ultrascroll option quickly scrolls new sonar data, but
with a reduced image quality. For most situations, the Fast
option provides a good balance between a quickly
scrolling image and targets that are less distorted.

Sonar Noise Rejection Settings
From a sonar view, select > Sonar Setup > Noise Reject.
Interference: Adjusts the sensitivity to reduce the effects of
interference from nearby sources of noise.
When you adjust the interference setting from off through
low , medium , and high , noise is gradually removed,
but there is little effect on the strong target returns. You
should use the lowest interference setting that achieves the
desired improvement to remove interference from the screen.
Correcting installation issues that cause noise is the best way
to eliminate interference.
Surface Noise: Hides sonar returns near the surface of the
water. Hiding surface noise helps reduce screen clutter.
Sonar 5
Surface noise is caused by interference between the
transducer and water. You can hide surface noise to help
reduce clutter. Wider beam widths (lower frequencies) can
show more targets, but can generate more surface noise.
TVG: Reduces surface noise.
This control is best used for situations when you want to
control and suppress clutter or noise near the water surface.

Troubleshooting
My device does not turn on
• Push the power cable all the way into the back of the device.
Even if the cable seems to be connected, you should push
firmly so that it is fully seated.
• Make sure the power source is generating power.
You can check this several ways. For example, you can
check whether other devices powered by the source are
functioning.
• Check the fuse in the power cable.
The fuse should be located in a holder that is part of the red
wire of the power cable. Check that the proper size fuse is
installed. Refer to the label on the cable or the installation
instructions for the exact fuse size needed. Check the fuse to
make sure there is still a connection inside of the fuse. You
can test the fuse using a multimeter. If the fuse is good, the
multimeter reads 0 ohm.
• Check to make sure the device is receiving at least 10 Vdc,
but 12 Vdc is recommended.
To check the voltage, measure the female power and ground
sockets of the power cable for DC voltage. If the voltage is
less than 10 Vdc, the device will not turn on.
My sonar does not work
• Push the transducer cable all the way into the back of the
device.
Even if the cable seems to be connected, you should push
firmly so that it is fully seated.
• Check to make sure the sonar transmission is turned on.
My device is not creating waypoints in the correct
location
You can manually enter a waypoint location to transfer and
share data from one device to the next. If you have manually
entered a waypoint using coordinates, and the location of the
point does not appear where the point should be, the map
datum and position format of the device may not match the map
datum and position format originally used to mark the waypoint.
Position format is the way in which the GPS receiver’s position
appears on the screen. This is commonly displayed as latitude/
longitude in degrees and minutes, with options for degrees,
minutes and second, degrees only, or one of several grid
formats.
Map datum is a math model which depicts a part of the surface
of the earth. Latitude and longitude lines on a paper map are
referenced to a specific map datum.
1 Find out which map datum and position format was used
when the original waypoint was created.
If the original waypoint was taken from a map, there should
be a legend on the map that lists the map datum and position
format used to create that map. Most often this is found near
the map key.
2 Select Settings > Units.
3 Select the correct map datum and position format settings.
