furuno ls4100 fish finder manual

WATER TYPE: Choose the water type with which to use the LS-4100, from Salt or Fresh. KEY BEEP: Turn key beep on or off. BATT VOLTAGE: Turn the battery voltage indication (appears at the top right corner on the screen) on or off. Page 3 BASIC RANGE 1 - BASIC RANGE 8: Set range of each of the eight basic. Only qualified personnel should work inside the equipment. 3.1 Maintenance Regular maintenance is essential for good performance. Checking the items listed in the table below monthly will help keep your equipment in good shape for years to come. For any NG, request service. (A special connector is required to test the NMEA port. Nothing appears if no connector is connected.) 5. When choosing a location keep the following in mind: Keep the display unit out of direct sunlight. For planing hulls, a practical location is generally rather far astern, so that the transducer is always in water regardless of the planing attitude. This may require a certain amount of experimentation for fine tuning at high cruising speeds. 4. Fill the gap between the wedge front of the transducer and transom with epoxy material to eliminate any air spaces. Mounting location To ensure the best performance, the sensor must be submerged in aeration-free and turbulence-free water. Mount the sensor close to the centerline of the boat. Mark this mounting hole. 5. If a hole has been drilled in the transom, open the appropriate slot in the transom cable cover. Position the cover over the cable where it enters the hull. Refer to the interconnection diagram to connect cables. Leave slack in cables to facilitate checking and maintenance. The transmission speed for both input and output is 4800 bps. Data is output at two-second intervals. Input data sentences. Off: Outputs the data sentences of LS-4100 only. On: Outputs the data sentences of LS-4100 and sentences which are input from other equipment. 6. To restore normal operation, turn off the power and then turn it on again.

Do not remove the label. If the label is missing or damaged, contact a FURUNO agent or dealer. WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside. FURUNO will assume no responsibility for any damage associated with improper installation. Use the specified power cable. The main features of the LS-4100 are Bright 5-inch monochrome LCD gives excellent readability even in broad daylight. Automatic function permits unattended adjustment of range and gain. The unit beeps, the startup screen appears, and then the equipment checks the ROM and RAM for proper operation and displays program number. The time remaining until power is turned off is counted down on the screen. The lower the frequency of the signal, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition. 200 kHz The higher the frequency of the ultrasonic signal the better the. This mode is useful for determining bottom contour. When the bottom depth increases, the display shift to keep the bottom echo at the lower part of the screen. Page 1 or Page 2 of the main menu appears depending on the page last used. The auto mode in use is shown as (Auto-Fishing) or (Auto-Cruising) at the top left corner on the screen. Note: When in the auto mode, SHIFT and CLUTTER cannot be adjusted manually. Shifting the range The basic range may be shifted up or down in the manual mode as follows: Window can be shifted up and down to select the depth. Display Range and display shift concept 1.
