WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based Augmentation System) navigation system. An SBAS provider furnishes GPS signal corrections to SBAS users. Two more SBAS providers are also currently under development, MSAS (Multi-Functional Satellite Augmentation System) for Japan and EGNOS (Euro Geostationary Navigation Overlay Service) for Europe. All providers will be compatible with one another, thus providing “seamless” position fixes to SBAS users. 150°W 120°W 90°W 60°W 30°W 0 30°E 60°E 90°E 120°E 150°E 150°W 120°W 90°W 60°W 30°W 0 30°E 60°E 90°E 120°E 150°E 0 20°S 40°S 60°S 20°N 40°N 60°N 0 20°S 40°S 60°S 20°N 40°N 60°N WAAS EGNOS MSAS Satellite, Region Position 120, AOR-E 15.5°W 122, AOR-W 54°W 131, IOR 64.5°E 134, POR 178°E 131 134 122 120 Initial operation time WAAS: 2003 EGNOS: 2004 MSAS: 2005 At the time of this software release, SBAS is still under development. (Providers are expected to have initial operations capability from the times shown above.) During this developmental period, which may last for several years, there is no guarantee of the accuracy, integrity, continuity, or availability of the SBAS signal. Furuno will accept no responsibility for the use of the signal for other than the above stated purpose. It is the user’s responsibility to exercise common prudence and navigational judgment while using the SBAS signal in the developmental phase. Note: This manual uses “WAAS” when referring to any SBAS provider.

2.1 Principle of 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 display unit. 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. ---- ---- ---- 0 50 150 100 Underwater conditions and video sounder display

Press the RETURN soft key to manually close the window, or wait 10 seconds and the window automatically closes. 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. 50 kHz 200 kHz Comparison of transducer frequencies

2-5 2.5 Automatic Sounder Operation Automatic sounder operation is useful when you are preoccupied with other tasks and do not have time to adjust the display. How the automatic sounder works The automatic sounder function automatically selects the proper gain, range scale and clutter suppression level according to depth. It works as follows: • Range changes automatically to display the bottom echo on the screen. • 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. Two 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. How to enable automatic sounder operation 1. To show the mode/freq window: Normal sounder display: Press the MODE/FREQ soft key. Plotter/sounder display: Press the SNDR, MODE/FREQ soft keys in order. Dual-frequency display: Press the MODE soft key. MODE/FREQ L AUTO CRUISING AUTO FISHING MANUAL M Mode/frequency window 2. Press ▲ or ▼ to select AUTO CRUISING or AUTO FISHING. 3. Press the RETURN soft key to close the window, or wait 10 seconds and the window closes automatically. 2.6 Manual Sounder Operation Manual operation is useful for observing fish schools and bottom using a fixed gain setting. The gain, clutter, range and range shifting functions used together give you the means to select the depth you can see on 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. Selecting the manual mode 1. Press the appropriate soft keys to show the MODE/FREQ window. 2. Select MANUAL. 3. Press the RETURN soft key.

2-11 2.15 Interpreting the Display Zero line 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. Zero line Shift Zero line Minute mark Minute mark shows time with two colored bar. Each bar is 30 sec. 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. Small school Large school Size of fish school Fish school echoes Bottom echo Echoes from the bottom are normally the strongest and are displayed in reddish-brown color 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. Intensity difference in water depth Second bottom echo Rock base Mud and sand Bottom echoes

2-12 Surface noise/Aeration 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. Surface noise Caused by aerated water Thermocline Surface noise/aeration

Press ▲ or ▼ to select the chart system you are using. If UNKNOWN appears in the GEODETIC DATUM window, select a different chart system to show the proper chart datum. 4. Press the ENTER soft key or the [ENTER] key to register your selection. POS SMOOTHING When the DOP or receiving condition is unfavorable, the GPS fix may change, even if the vessel is dead in water. This change can be reduced by smoothing the raw GPS fixes. A setting between 000 to 999 is available. The higher the setting, the more smoothed the raw data, however too high a setting slows response time to change in latitude and longitude. This is especially noticeable at high ship’s speeds. 000 is the normal setting; increase the setting if the GPS fix changes. SPD/CSE SMOOTHING During position fixing, ship’s velocity (speed and course) is directly measured by receiving GPS satellite signals. The raw velocity data may change randomly depending on receiving conditions and other factors. You can reduce this random variation by increasing the smoothing. Like with latitude and longitude smoothing, the higher the speed and course smoothing the more smoothed the raw data. If the setting is too high, however, the response to speed and course change slows. For no smoothing, enter all zeroes. The default setting is 005 (sec). GPS SPEED AVE Calculation of ETA is based on average ship’s speed over a given period. If the period is too long or too short calculation error will result. Change this setting if calculation error occurs. The default setting is 60 seconds, which is suitable for most conditions. LAT OFFSET, LON OFFSET GPS-generated position may be off from the chart. In this case, you can apply an offset to GPS position to refine position accuracy. Mark the equipment indication on the chart, and then calculate the L/L error. 1. Select LAT OFFSET or LON OFFSET. 2. Press the EDIT soft key. 3. Key in the error value. To switch the north and south (east and west), press the N<->S (W<->E) soft key. 4. Press the ENTER soft key or [ENTER] key. DISABLE SATELLITE Every GPS satellite is broadcasting abnormal satellite number(s) in its Almanac, which contains general orbital data about all GPS satellites, including those which are malfunctioning. Using this information, the GPS receiver automatically eliminates any malfunctioning satellite from the GPS satellite schedule. However, the Almanac sometimes may not contain this information. If you hear about a malfunctioning satellite from another source, you can disable it manually. Enter satellite number (max. 3 satellites) in two digits and press the ENTER soft key or the [ENTER] key.

11-10 SYSTEM SETUP menu description FISH ALM LVL: Sets the fish alarm sensitivity; namely, which echo strength will trigger the alarm. HIGH, only the strong echoes (red and reddish brown) trigger the alarm; NORMAL, echoes from strong to medium strength (greater than yellow) trigger the alarm, LOW, any echo (greater than light-blue) triggers the alarm. TX POWER: Turns TX power on/off. TVG 200kHz, TVG 50kHz: TVG (Time Varied Gain) compensates for propagation attenuation of the ultrasonic waves. It does this by equalizing echo presentation so that fish schools of the same size appear in the same density in both shallow and deep waters. In addition, it reduces surface noise. Note that if the TVG level is set too high short range echoes may not be displayed. Fish school B Fish school A TVG concept ECHO OFFSET 200kHz, ECHO OFFSET 50kHz: If the on-screen echo level appears to be too weak or too strong and the level cannot be adjusted satisfactorily with the gain control, adjust echo offset to compensate for too weak or too strong echoes. SEABED LVL 200kHz, SEABED LVL 50kHz: If the depth indication is unstable in automatic operation or the bottom echo cannot be displayed in reddish-brown by adjusting the gain control in manual operation, you may adjust the bottom echo level detection circuit, for both 50 kHz and 200 kHz, to stabilize the indication. Note that if the level is set too low bottom echoes cannot be acquired and if set too high regards the fish school as the bottom, so the depth indication will not be fixed. The default setting for both 200 kHz and 50 kHz is 80.
