1. Introdución
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. Compoñentes 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. Configuración e instalación
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. Compoñentes de conexión
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. Conexión de alimentación
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. Acendido e configuración iniciais
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. Instrucións de funcionamento
The SC702 display unit is designed for intuitive operation using its integrated buttons and clear display.
4.1. Mostrarview
The main display screen provides real-time navigation data. Key indicators include:
- SPD (velocidade): 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 (Ruta sobre o chan): Displays the actual direction of the vessel's movement over the ground.
- CORRECCIÓN: 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: Número de satélites en view.
4.2. Funcións dos botóns
The SC702 features several dedicated buttons for easy navigation and control:
- BRILL: Adjusts the display brightness. Press repeatedly to cycle through brightness levels.
