Furuno SC702 Display Unit User Manual

1. Въведение

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. Компоненти надview

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. Настройка и инсталация

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

3.4. Първоначално включване и конфигурация

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. Инструкции за работа

The SC702 display unit is designed for intuitive operation using its integrated buttons and clear display.

4.1. Показване надview

The main display screen provides real-time navigation data. Key indicators include:

• SPD (Скорост): 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.
• КОРЕКЦИЯ: 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: Брой сателити в view.

4.2. Функции на бутоните

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.
