Reading the XTE (cross-track error) monitor
The XTE monitor, located below the compass rose, shows the distance you are off course and the direction to steer to return to course. The own ship marker moves according to direction and distance off course. It is shown in black when the amount of cross-track error is within the XTE monitor range and yellow when it is over. An arrow appears at the right or left side of the XTE monitor and it shows the direction to steer to return to intended course. It is shown in red when you should steer left, and green when you should steer right. In the example on the previous page you would steer right to return to course. To maintain course, steer the vessel so the own ship marker stays at the center of the XTE monitor.

3. PLOTTER OPERATION
The highway display, shown in combination displays, provides a graphic presentation of ship’s track along intended course. It is useful for monitoring ship’s progress toward a waypoint. The own ship marker shows the relation between ship and intended course. The XTE monitor shows the direction and amount your vessel is off course – the arrow shows the direction to steer to return to your course and the numeric the distance you are off course. Using the figure below as an example, you would steer right 0.009 nm to return to course.
To maintain course, steer the vessel so the own ship marker stays aligned with the intended course line.

3.6.4 Track plotting method and interval for own ship track
In drawing the own ship track, first the ship’s position fed from position-fixing equipment is stored into the unit’s memory at an interval of time or distance. A shorter interval provides for better reconstruction of the track, but the storage time of the track is reduced. When the track memory becomes full, the oldest track is erased to make room for the latest.
Track plotting method
Track may be plotted by time or distance. The default setting is “time.”

3.8 Waypoints
In navigation terminology, a waypoint is a particular location on a voyage whether it be a starting, intermediate or destination point. A waypoint is the simplest piece of information your equipment requires to get you to a destination, in the shortest distance possible.
This unit has 999 waypoints into which you can enter position information. You may enter a waypoint five ways: at own ship position, at MOB position (see page
1-14 for details), by cursor, by range and bearing, and through the waypoint list
(manual input of latitude and longitude).
Entering a waypoint at own ship position
Press the [SAVE/MOB] key momentarily to store your position as a waypoint.
This new waypoint is saved to the waypoint list, under the youngest empty waypoint number.
Entering a waypoint with the cursor
1. Press the [MENU] key to open the menu.
2. Press the WAYPOINTS/ROUTES, WAYPOINTS and WAYPOINT BY
CURSOR soft keys. The plotter display appears.
3. Operate the trackball to place the cursor where you want to enter a waypoint.
4. Press the NEW WPT soft key. The waypoint window appears and it shows waypoint mark shape, waypoint name, comment (default: time and date), position of waypoint and proximity alarm radius.

3.9 Routes
Often a trip from one place to another involves several course changes, requiring a series of route points (waypoints) which you navigate to, one after another. The sequence of waypoints leading to the ultimate destination is called a route. Your unit can automatically advance to the next waypoint on a route, so you do not have to change the destination waypoint repeatedly.
You can store up to 200 routes, and a route may have 35 waypoints.

With connection of the optional Network Sounder ETR-6/10N you can show video sounder images on the display.
4.1 Principle Operation
The video sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on screen. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source (transducer).
Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflected sound wave, the depth to the object can be determined.
The entire process begins in the network sounder. Transmitter power is sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any returning signals from intervening objects (such as a fish school) are received by the transducer and converted into an electrical signal. The signals are then amplified in the amplifier section, and finally, displayed on screen.
The picture displayed is made up of a series of vertical scan lines, one for each transmission. Each line represents a snapshot of what has occurred beneath the boat. A series of snapshots are accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are displayed.

50 kHz picture
The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition.
200 kHz picture
The higher the frequency of the ultrasonic pulse the better the resolution.
Therefore, the 200 kHz frequency is ideal for detailed observation of fish school.

4.3 Automatic Sounder Operation
Automatic sounder operation is useful when you are preoccupied with other tasks and do not have the time to adjust the display.
4.3.1 How the automatic sounder works
The automatic sounder function automatically selects the proper gain, range scale and clutter suppression level according to the depth. It works as follows:
• The range changes automatically to locate the bottom on the lower half of the screen. The range jumps to one step shallower range when the bottom echoes reach a half way point of the full scale from the top and to one step deeper range when they come to the lower edge of the scale.
• The gain is automatically adjusted to display the bottom echo in reddish brown
(default color arrangement).
• Clutter, which suppresses low level noise, is automatically adjusted.
4.3.2 Types of automatic sounder modes
Two types of automatic sounder modes are available: CRUISING and FISHING.
CRUISING is for tracking the bottom, and FISHING is for searching fish schools.
CRUISING uses a higher clutter rejection setting than FISHING therefore it is not recommended for fish detection - weak fish echoes may be erased by the clutter suppression circuit.
4.3.3 How to enable automatic sounder operation
1. If not displayed, press the [HIDE/SHOW] key to show the sounder soft keys.
2. Press the AUTO/D. BOX soft key.

4.4 Manual Sounder Operation
Manual operation is useful for observing fish schools and bottom using a fixed gain setting.
The gain, range and range shift functions used together give you the means to select the depth you can see on the screen. The basic range can be thought of as providing a “window” into the water column and range shifting as moving the
“window” to the desired depth.
4.4.1 Selecting the manual mode
1. If not displayed, press the [HIDE/SHOW] key to show the sounder soft keys.
2. Press the AUTO/D. BOX soft key to show the mode/frequency window.

4.12.6 When an alarm setting is violated...
When an alarm setting has been violated the buzzer sounds and the speaker icon appears in red. Press the [CLEAR] key to silence the alarm. At this time the color of the speaker icon changes from red to background color. You can see which alarm has been violated on the alarm menu display. In the example below the bottom alarm has been violated.
To see which alarm(s) has been violated:
1. Press the [ALARM] key. The name of the offending alarm is shown in the
ALARM INFORMATION window.

2. Press the CLEAR ALARM soft key to acknowledge the alarm (and silence the buzzer if it has not already been done with the [CLEAR] key). The color of the speaker icon changes from red to background color. The icon remains on the screen until the reason for the alarm is eliminated or the alarm is disabled. If more than one alarm has been violated, the message CONTINUE appears at the bottom of the alarm information window. In this case, press the NEXT
INFO soft key to see which other alarms have been violated.
Note: The alarm icon is red when an alarm setting is violated, and changes to background color when the [CLEAR] key or CLEAR ALARM soft key is pressed. The color remains the same regardless of how many times another alarm is violated.
3. Press the [ALARM] key to close the menu.

4.14 Interpreting the Sounder Display
The zero line (sometimes referred to as the transmission line) represents the transducer’s position, and moves off the screen when a deep phased range is used.

Echoes from the bottom are normally the strongest and are displayed in reddish-brown, but the color and width will vary with bottom composition, water depth, frequency, sensitivity, etc.
In a comparatively shallow depth, a high gain setting will cause a second or sometimes a third or a fourth echo to be displayed at the same interval between them below the first echo trace. This is because the echo travels between the bottom and the surface twice or more in shallow depths.
The color of the bottom echo can be used to help determine the density of the bottom materials (soft or hard). The harder the bottom, the wider the trace. If the gain is set to show only a single bottom echo on mud, a rocky bottom will show a second or third bottom return. The range should be chosen so the first and second bottom echoes are displayed when bottom hardness is being determined.

4.14.3 Fish school echoes
Fish school echoes will generally be plotted between the zero line and the bottom. Usually the fish school/fish echo is weaker than the bottom echo because its reflection property is much smaller compared to the bottom. The size of the fish school can be ascertained from the density of the display.

When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. As surface turbulence is acoustically equivalent to running into a brick wall, the bottom echo will be displayed intermittently. Similar noise sometimes appears when a water temperature difference (thermocline) exists. Different species of fish tend to prefer different temperature zones, so the thermocline may be useful to help identify target fish. 200 kHz tends to show shallow thermoclines better than 50 kHz.
In rough waters the display is occasionally interrupted due to below-the-ship air bubbles obstructing the sound path. This also occurs when the boat makes a quick turn or reverses movement. Lowering the picture advance speed may reduce the interruption. However, reconsideration of the transducer installation may be necessary if the interruption occurs frequently.
