- RANGE / GAIN: Use these buttons to adjust the depth range displayed on the screen and to control the sensitivity (gain) of the sonar receiver. Increasing gain can show weaker returns, but may also increase clutter.
- Directional Pad (Arrows): Navigate through menus and adjust settings.
- FUNC / MARK: The Function button can be assigned to various quick-access features. The Mark button allows you to mark specific locations or sonar returns on the display.
- BRILL (Brightness): Adjust the brightness of the LCD display for optimal viewing in various light conditions.
Upon powering on, the FCV600 will typically display the sonar screen, showing real-time underwater information. The depth reading (e.g., 20.5 meters) is prominently displayed. The colored returns indicate different strengths of sonar echoes, helping to distinguish fish, bait, and bottom structure.
4. Maintenance
Regular maintenance ensures the longevity and performance of your Furuno FCV600:
- Cleaning: Wipe the display and unit exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. For the screen, use a specialized screen cleaner if necessary.

- Connections: Check all cable connections regularly for corrosion or looseness. Apply dielectric grease to electrical connections to prevent moisture ingress.
- Storage: When not in use for extended periods, store the unit in a dry, cool place, away from direct sunlight and extreme temperatures. If possible, disconnect it from the power source.
5. Troubleshooting
If you encounter issues with your FCV600, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on | No power, loose connection, blown fuse | Check power cable connection, inspect fuse in power line, ensure battery is charged. |
| No sonar display / No depth reading | Transducer not connected, transducer fouled, incorrect settings | Verify transducer connection, clean transducer face, check 'Gain' and 'Range' settings. |
| Screen is dim or unreadable | Brightness setting too low, direct sunlight | Adjust 'BRILL' setting. Reposition unit if possible to avoid direct glare. |
