Bottom Presentation
As the boat moves, your Matrix Fishing System charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance.
Bottom Contour Profile with RTS Window. Temp/Speed Accessory is optional.
Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display.
Structure ID represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display.
Hard Bottom Soft Bottom Rocky Bottom
WhiteLine highlights the strongest sonar returns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.
The sonar returns from the bottom, structure and fish can be represented as either Inverse (default), WhiteLine, Structure ID, or Bottom Black. See Sonar X-Press Menu: Bottom View for details on how to set the bottom view. Bottom Black displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display. Any targets such as fish, structure and thermoclines will be shown using the Structure ID method.

When Beam Select is set to 455 kHz, the returns from the 455 kHz narrow beams will be displayed in all views, and the maximum depth capability of your unit will be 240 ft (75 m). When the depth is greater than 240 ft (75 m), Beam Select should be set to 83 kHz. The unit will continue to acquire sonar returns below 240 ft and will be displayed in the 2D Sonar View.

NOTE: It is important to re-set Beam Select to 455 kHz when returning to water shallower than 240 ft (75 m) for maximum performance in the 3D views.
To change Beam Select: 1. Highlight Beam Select on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 455 kHz beam or the 83kHz beam. (455 kHz, 83 kHz, Default = 455 kHz)

Page 40

Fish ID+
Fish ID+ uses advanced signal processing to interpret sonar returns, and will display a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Fish symbols come in three different sizes to indicate the intensity of the return; in addition, there is a unique symbol set associated with each of the six beams, for a total of 18 possible fish symbols which can be displayed. The following graphic illustrates the different Fish ID+ symbols and shows the beams with which they are associated. For instance, a hollow fish facing left indicates it was detected in the far left beam and a hollow fish facing right indicates it was detected in the far right beam.

Fish Sensitivity

Fish Sensitivity adjusts the threshold of the Fish ID+ detection algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish. Fish Sensitivity is used in conjunction with Fish ID+. Fish ID+ must be set to either Symbol Only or Symbol+Depth for Fish Sensitivity to affect the ability of your Matrix Fishing System to identify sonar returns as fish. To change the Fish Sensitivity setting: 1. Highlight Fish Sensitivity on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish Sensitivity setting. (Low = 1, High = 10, Default = 5)

NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this. Also, make sure that the Water Type is set accurately, especially in salt water, as this affects the accuracy of deep water depth readings.

Noise Filter

Noise Filter adjusts the sonar noise filter to limit interference on the display from sources such as your boat engine, turbulence, or other sonar devices. The Noise Filter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: The Off setting removes all filtering; Low, Medium and High settings add progressive filtering of the sonar returns. In some deep water situations, the High setting may actually hinder your units ability to find the bottom.

Troubleshooting

Before contacting the Humminbird Customer Resource Center, please read the following section. Taking the time to review these troubleshooting guidelines may allow you to solve a performance problem yourself, and therefore avoid sending your unit back for repair.

Matrix Doesnt Power Up

If your Matrix Fishing System doesnt power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that:
NOTE: Accessories Menu (no accessories attached)
the power cable is properly connected to the Matrix control head, the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground
Accessories Menu (with accessories attached)
the fuse is operational the battery voltage of the power connector is at least 10 Volts. Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.
Accessories to enable WeatherSense, GPS Functionality and the SmartCast Wireless Sonar Link require separate purchases. You can visit our website at www.humminbird.com or contact our Customer Resource Center at 1-800-633-1468 for additional details.
Matrix Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started Matrix Fishing System to go into Normal operating mode automatically. If, when you power up your unit, it goes into Simulator mode automatically, even though a transducer is already connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks: Using the Installation Guide that also comes with your Matrix Fishing System, check to make sure that the transducer cable is securely connected to your unit. Reconnect if necessary, and power up the unit again to see if this fixes the problem. Replace the non-functioning transducer with a known good transducer if available and power up the control head again. Check the transducer cable. Replace the transducer if the cable is damaged or corroded.

Page 60

Display Problems
There are several main conditions or sources of possible interference that may cause problems with the quality of the information displayed on the control head. Look in the following table for some symptoms of display problems and possible solutions: Problem
The control head loses power at high speeds.
Finding the Cause of Noise
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference: Possible Source of Noise

Other electronic devices

Isolation
Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. To determine whether the boats engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15 (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.

Possible Cause

If the power output of your boats engine is unregulated, the control head may be protecting itself using its over-voltage protection feature. Make sure the input voltage does not exceed 20 Volts. The transducer position may need to be adjusted. A mix of air and water flowing around the transducer (cavitation) may be interfering with the interpretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.

The boats engine

When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.
There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty.
Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty. Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean. Low battery voltage may be affecting the power of signal transmission. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
