Bottom Presentation
As the boat moves, the unit 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.
NOTE: A sloping bottom will be represented as a thicker line across the display. Also, harder bottoms will be typically displayed with red and softer bottoms will be typically displayed with blue.

Key Functions

Your Humminbird user interface consists of a set of easy-to-use keys that work with various on-screen views and menus to give you flexibility and control over your fishing experience.

POWER/LIGHT Key

The POWER/LIGHT key is used to turn the FishFinder on and off, and also to adjust the backlight and background color of the display. Press the POWER/LIGHT key to turn the unit on. The Title screen is then displayed until the FishFinder begins sonar operation. To adjust the backlight, or to adjust the display background color, press the POWER/LIGHT key to access the Light and Background menu. Use the 4-WAY Cursor key to select Light or Background and then use the LEFT or RIGHT Cursor key to change the settings. Press EXIT to exit the Light and Background menu. Press and hold the POWER/LIGHT key for 3 seconds to turn the unit off. A message will appear telling you how many seconds there are until shutdown occurs. Your FishFinder should always be turned off using the POWER/LIGHT key. This will ensure that shutdown occurs properly and any menu settings will be saved.

The sonar returns from the bottom, structure and fish can be represented as either Structure ID, or WhiteLine. See Sonar X-Press Menu: Bottom View for details on how to set the bottom view. Structure ID represents weak returns in blue and strong returns in red.

VIEW Key

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 VIEW key is used to cycle through all available views. Press the VIEW key to advance to the next view. Repeatedly pressing VIEW cycles through all views available. Views can be hidden to optimize the system to your fishing requirements (see Setup Menu Tab: Select Views, Advanced).

MENU Key
The MENU key is used to access the menu system. Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-Press Menu - Press the MENU key once for the Sonar X-Press Menu. The X-Press menu allows you to access frequently-used settings without having to navigate through the whole menu system. When the X-Press menu is displayed, you can use the UP or DOWN Cursor keys to move to a particular menu choice. As soon as you alter a parameter (using the RIGHT or LEFT Cursor keys) the X-Press menu will collapse temporarily, and the screen will update if it is affected by your menu setting change, allowing you to see the effects of your action immediately. Reactivate the X-Press Menu by using the UP or DOWN Cursor keys. Main Menu - Press the MENU key twice for the tabbed Main Menu System. The Main Menu System is organized under tabbed headings to help you find a specific menu item quickly: Alarms, Sonar and Views tabs are part of your tabbed Main Menu System. Use the LEFT or RIGHT 4-Way Cursor Control key to select a tab; then use the DOWN or UP key to select the menu item, and the LEFT or RIGHT key to alter a menu setting.

Powering Up the Unit

Turn on your FishFinder by pressing the POWER/LIGHT key. The Title screen is displayed until the FishFinder begins operation. Your FishFinder will begin Normal or Simulator operation, depending on the presence or absence of a transducer.
FishFinder 585c Title Screen

The Menu System

The menu system is divided into easy-to-use menu modules. The main components of the menu system are: Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-Press Menu - The X-Press menu allows you to access the settings that are changed frequently without having to navigate through the whole menu system. Press the MENU key once to display the X-Press Menu. When you select a menu item from the X-Press menu, the menu will collapse, leaving only the menu choice on the screen. Use the Up or Down Cursor keys to reactivate the X-Press menu.

Sonar Tab, Normal Mode

User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the highest level of control over the FishFinder, and Normal Mode for users who desire greater simplicity and fewer menu choices. Additional Advanced menu choices will be displayed throughout the menu system when you navigate to specific menus while in Advanced Mode. Any changes made while in Advanced Mode will remain in effect after you switch back to Normal Mode. See Setup Menu Tab: User Mode for specific instructions on changing to Advanced User Mode. Total Screen Update - when you change any menu settings that affect the Sonar View, the view will update immediately (i.e. you dont have to exit the menu to apply the change to the screen).

Normal Operation

Use Normal operation for on the water operation with a transducer connected. In addition, your FishFinder uses advanced transducer detection methods to determine if a transducer is connected. If a functioning transducer is connected, Normal operation will be selected automatically at power up and your FishFinder can be used on the water. Exit Normal operation by powering your FishFinder off.

Sonar Tab, Advanced Mode

Simulator

Use the Simulator to learn how to use your FishFinder before taking your boat on the water. The Simulator is a very powerful tool that simulates on the water operation, providing a randomly-updated display. We recommend going through this manual while using the Simulator, since all of the menus function and affect the display the way they actually do when in Normal operating state.
NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually from the Start-Up Options menu as opposed to letting the FishFinder enter Simulator automatically (as it will if a transducer is not connected and you do nothing during power up). Manually selecting Simulator from the Start-Up Options menu allows you to pre-configure your FishFinder for on the water operation. Any menu changes you make will be saved for later use.

System Status

Use System Status to view system connections and to conduct a unit self-test. The following screens are displayed in turn when you press the VIEW button when using System Status: Self Test Accessory Test. Self Test displays results from the internal diagnostic self test, including unit serial number, Printed Circuit Board (PCB) serial number, software revision, total hours of operation and the input voltage.
NOTE: Your new unit may show many hours of operation due to product testing performed at the manufacturing facility.
A message will appear on the display periodically to remind you that you are using the Simulator. Exit the Simulator by powering your FishFinder off.

Sonar X-Press Menu

The Sonar X-Press menu provides access to the settings most frequently-used. Press the MENU key once while in any of the Sonar Views to access the Sonar X-Press menu.
NOTE: Upper Range only appears in Advanced User Mode when in Sonar or Big Digits View. NOTE: Zoom Level only appears in Sonar Zoom View.

Sensitivity

Sensitivity controls how much detail is shown on the display. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish.

Sensitivity at Low

Sensitivity at Medium

Sensitivity at High

To adjust the Sensitivity: 1. Highlight Sensitivity on the Sonar X-Press menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10)

Page 24

Upper Range
(Advanced: Sonar and Big Digits Views Only)

Chart Speed

Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown. A faster speed shows more information in the Sonar View and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret. Regardless of the Chart Speed setting, the RTS Window will update at the maximum rate possible for the depth conditions. Adjust Chart Speed to your personal preference. To adjust the Chart Speed: 1. Highlight Chart Speed on the Sonar X-Press menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the Chart Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 4)
Upper Range sets the shallowest depth range that will be displayed on the Sonar and Big Digits Views. The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). Upper Range is often used with Lower Range.

For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet.
To adjust the Upper Range: 1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-Press menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the Upper Range setting. (0 to 990 feet or 0 to 327 meters [International Models Only], Default = 0)

Bottom View

Bottom View selects the method used to represent bottom and structure on the display. Structure ID represents weak returns in blue and strong returns in red. 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. (See Bottom Presentation for more information.) To adjust the Bottom View: 1. Highlight Bottom View on the Sonar X-Press menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID)
Lower Range sets the deepest depth range that will be displayed. Automatic is the default setting. When in automatic mode, the lower range will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth range into Manual mode. Use both Upper and Lower Range together to view a specific depth range manually when looking for fish or bottom structure. M will be displayed in the lower right corner of the screen when you start manually adjusting the Lower Range to indicate that you are in Manual mode.
For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, allowing you to see a more detailed view than you would see if the display went all the way to the bottom.

Water Type configures your unit for operation in fresh or salt water. The Water Type menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).
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.
To change the Noise Filter setting: 1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Noise Filter setting. (Off, Low, Medium, High, Default = Low)
To change the Water Type setting: 1. Make sure you are in Advanced User Mode, then highlight Water Type on the Sonar main menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Water Type setting. (Fresh, Salt, Default = Fresh)

Max Depth

Max Depth adjusts the maximum depth of operation. The performance of your FishFinder can be tuned to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is set, your FishFinder will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the FishFinder will acquire bottom readings as needed (within the capacity of the unit). If the bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating that the FishFinder cannot locate the bottom. The Max Depth menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). To change the Max Depth setting: 1. Make sure you are in Advanced User Mode, then highlight Max Depth on the Sonar main menu. 2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Max Depth setting. (AUTO, 10 to 1000 feet or 3 to 330 meters [International Models Only], Default = AUTO)

Setup Menu Tab

From any view, press the MENU key twice to access the tabbed Main Menu System, then press the RIGHT cursor key until the Setup tab is selected. NOTE:

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.

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.

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.
FishFinder Doesnt Power Up If your FishFinder doesnt power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that:

the power cable is properly connected to the FishFinder control head, the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground 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.
When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.
FishFinder Defaults to Simulator with a Transducer Attached A connected and functioning transducer will cause the newly-started FishFinder to go into Normal operating mode automatically. If, when you power up the FishFinder, 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 FishFinder, check to make sure that the transducer cable is securely connected to the FishFinder. Reconnect if necessary, and power up the FishFinder again to see if this fixes the problem. Replace the transducer with a known good transducer if available and power up the control head again. Check the transducer cable and connector. Replace the transducer if the cable is damaged or corroded.
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.

Page 46

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

Specifications
Depth Capability... 1000 ft (330 m) Power Output.... 300 Watts (RMS) 2400 Watts (Peak to Peak) Operating Frequency.. 200 kHz Single Beam Area of Coverage... 20 @ -10 dB in 200 kHz Target Separation... 2 Inches (63.5 mm) Power Requirement... 10-20 VDC LCD Matrix... 320 V x 240 H TFT Color Transducer.... XHS-9-20-T Transducer Cable Length... 20 ft (6 m)

How to Isolate It

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.
