1. Introduction
The Furuno SC702 is the display unit component of the SC70/SC130 Satellite Compass system. This system utilizes advanced GNSS (Global Navigation Satellite System) technology, including GPS, Galileo, and GLONASS, to provide highly accurate navigation data. The SC702 display unit presents critical information such as heading, speed over ground (SOG), course over ground (COG), and rate of turn (ROT), essential for safe and precise vessel operation. This manual provides detailed instructions for the setup, operation, and maintenance of your SC702 display unit.
2. Components Overview
The SC70/SC130 Satellite Compass system typically includes the following main components:
- SC701 - Junction box for SC70/SC130
- SC702 - Display unit for SC70/SC130 (This manual's focus)
- SC703 - ANT 2GPS/ANG/ACCEL/MGNT SNSR (GPS Antenna)
3. Setup and Installation
Proper installation is crucial for the optimal performance of your Furuno SC70/SC130 system. It is highly recommended that installation be performed by a qualified marine electronics technician.
3.1. Mounting the SC702 Display Unit
The SC702 display unit can be mounted on a dashboard or panel. Ensure the mounting location is secure, provides good visibility, and is protected from direct exposure to harsh weather conditions if not rated for such exposure. Allow sufficient space for cable connections at the rear of the unit.
3.2. Connecting Components
Connect the SC702 Display Unit, SC701 Junction Box, and SC703 GPS Antenna using appropriate cables (sold separately). The junction box acts as the central hub for power and data distribution. Refer to the detailed wiring diagrams provided in the full installation manual for specific connection points and cable types. Ensure all connections are secure and waterproofed as necessary.
3.3. Power Connection
Connect the system to a stable DC power source (typically 12-24V DC) via the SC701 Junction Box. Ensure proper fusing and circuit protection are in place according to marine electrical standards.
3.4. Initial Power-On and Configuration
After all components are connected, power on the system. The SC702 display will initiate. Follow the on-screen prompts for initial setup, including language selection, time zone, and basic navigation settings. Calibration of the compass may be required after installation to ensure maximum accuracy.
4. Operating Instructions
The SC702 display unit is designed for intuitive operation using its integrated buttons and clear display.
4.1. Display Overview
The main display screen provides real-time navigation data. Key indicators include:
- SPD (Speed): Displays the vessel's speed, typically Speed Over Ground (SOG).
- HDG (Heading): Shows the vessel's current heading in degrees, relative to true north.
- ROT (Rate Of Turn): Indicates how quickly the vessel is changing its heading, in degrees per minute.
- COG (Course Over Ground): Displays the actual direction of the vessel's movement over the ground.
- FIX: Indicates the GPS fix status (e.g., GP-3D for 3D GPS fix).
- PDOP: Position Dilution of Precision, an indicator of GPS accuracy. Lower values are better.
- COM.SV: Number of satellites in view.
4.2. Button Functions
The SC702 features several dedicated buttons for easy navigation and control:
- BRILL: Adjusts the display brightness. Press repeatedly to cycle through brightness levels.
- DISP: Cycles through different display screens or data views.
- MENU/ESC: Opens the main menu or acts as an escape/back button to exit current screens or cancel operations.
- ACK: Acknowledges alarms or messages.
- LIST: Accesses lists, such as waypoints, routes, or system logs.
- ENT: Enters or confirms a selection or input.
- Navigation Buttons (Up, Down, Left, Right): Used to navigate through menus, adjust settings, or move cursors on the screen.
4.3. Menu Navigation
Press the MENU/ESC button to access the main menu. Use the navigation buttons to scroll through menu options. Press ENT to select an option. Press MENU/ESC again to go back or exit the menu.
5. Maintenance
Regular maintenance ensures the longevity and reliable performance of your SC702 display unit and the entire satellite compass system.
5.1. Cleaning
Wipe the display screen and unit casing with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the display or casing. Ensure the unit is powered off before cleaning.
5.2. Software Updates
Periodically check the Furuno website or consult with a Furuno dealer for available software updates. Updates can provide performance enhancements, new features, or bug fixes. Follow the instructions provided with the update package carefully.
5.3. Cable and Connection Inspection
Regularly inspect all cables and connections for signs of wear, corrosion, or damage. Ensure all connections remain secure and waterproof, especially in a marine environment.
6. Troubleshooting
This section provides basic troubleshooting steps for common issues. For more complex problems, contact Furuno support or a certified service technician.
- No Power: Check power connections, fuses, and the vessel's power supply. Ensure the junction box is receiving power.
- No GPS Fix/Inaccurate Data: Ensure the GPS antenna has a clear view of the sky, free from obstructions. Check antenna cable connections. Verify the system's calibration.
- Display Issues: Adjust brightness using the BRILL button. If the screen is blank or distorted, power cycle the unit.
- System Alarms: Refer to the full system manual for specific alarm codes and their meanings. Press ACK to acknowledge alarms.
