4. Setup
4.1 Power Connection
The wireless signal tower requires a DC power source. Connect it to a 10V to 12.5V DC battery. Ensure the antenna is securely installed before connecting the power to the signal tower.
4.2 Transducer and Signal Tower Placement
The transducer and wireless signal tower should be positioned to ensure optimal signal transmission and reception. For boating, consider mounting the transducer in a location that provides an unobstructed view of the water beneath the boat, free from air bubbles or turbulence. The signal tower should be placed where its antenna has a clear line of sight to the main display unit.
4.3 Display Unit Mounting
The main display unit comes with a stand for easy placement. Secure the display unit in a convenient location on your boat or fishing platform, ensuring it is stable and visible during operation.
5. Operating Instructions
5.1 Powering On/Off
Press and hold the Power/Menu key to turn the fish finder on or off.
5.2 Basic Operation
Once powered on, the display will show real-time information including water depth, water temperature, fish location (represented by icons), and the bottom contour. The unit automatically adjusts some settings, but you can fine-tune them for specific conditions.
5.3 Adjusting Settings
Use the control buttons to navigate through the menu and adjust various settings:
- Sensitivity: Adjust the sonar sensitivity using the SEN key to filter out noise or detect weaker signals.
- Zoom: Use the Up/Down arrow keys to adjust the zoom level for a more detailed view of specific depth ranges.
- Units: Select preferred units for depth (meters/feet) and temperature (Celsius/Fahrenheit) through the menu.
- Depth Range: Manually set the depth range if needed.
- Alarms: Configure shallow alarm, fish alarm, and other alerts.
- Fish Icon: Toggle fish icons on/off or adjust their size representation.
- Chart Speed: Adjust the speed at which the sonar history scrolls across the screen.
- Language: Select your preferred language from the 20 supported options using the menu.
The fish finder has a built-in memory that stores your sonar settings even when the device is turned off.
6. Maintenance
- Cleaning: Wipe the display unit and other components with a soft, damp cloth after each use. Avoid abrasive cleaners or solvents.
- Storage: Store the fish finder in a dry, cool place when not in use. Disconnect the battery from the signal tower for long-term storage.
- Transducer Care: Ensure the transducer surface is clean and free from marine growth or debris for accurate readings.
7. Troubleshooting
7.1 Common Issues and Solutions
- No Power to Signal Tower: Ensure the DC battery is charged and properly connected (10V to 12.5V DC). Verify that the antenna is installed before connecting power.
- No Signal/Intermittent Signal: Check the connection between the antenna and the signal tower. Ensure the signal tower and display unit are within the wireless operating range (up to 980 feet/300m) and have a clear line of sight. Avoid obstructions.
- Inaccurate Depth Readings: Ensure the transducer is clean and properly submerged, free from air bubbles or turbulence. Adjust sensitivity settings if necessary.
- Display Issues: If the display is unclear, check the backlight settings using the Light Key.
7.2 Important Warnings
- Do not use an extension to the antenna as the antenna itself.
- Always install the antenna before connecting power to the signal tower.
- Ensure the signal tower and transducer are protected from excessive water exposure if they are not designed to be fully submersible.
8. User Tips
- Transmitter Sealing: While the device is designed for outdoor use, it is advisable to ensure the transmitter (signal tower with antenna) is adequately protected from direct water ingress, especially in heavy rain or splashing conditions, to prolong its lifespan.
- Language Settings: The device supports 20 languages. If you prefer a specific language like Portuguese or Polish, navigate to the language settings in the menu to select it.
- GPS Functionality: This specific model (FF918-CWLS) does not include GPS functionality. Its primary purpose is fish detection and depth/contour mapping.
- Complete Unit: The product is sold as a complete unit, including the display screen, wireless signal tower, and transducer. You do not need to purchase the screen separately.
