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.
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. It also allows for the display of targets near the surface that are otherwise hidden or masked by
surface noise.

Setting the Water Temperature Offset
You can set the temperature offset to compensate for the temperature reading from a temperature-capable
sensor.
1 Measure the water temperature using the temperature-capable transducer that is connected to the device.
2 Measure the water temperature using a different thermometer or temperature sensor that is known to be
accurate.
3 Subtract the water temperature measured in step 1 from the water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a positive number if the sensor connected to
the device measures the water temperature as being colder than it actually is. Enter this value in step 5 as
a negative number if the sensor connected to the device measures the water temperature as being warmer
than it actually is.
4 Select Settings > My Vessel > Temp. Offset.
5 Use the arrow keys to enter water temperature offset measured in step 3.

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.
4 Create the waypoint again.
