WARNINGS

Overvoltage Warning

If the input voltage to this unit rises above 125 VAC, the over- voltage detection circuit activates, an alarm sounds and the mes- sage OVERVOLTAGE appears at the screen center.

If this occurs, retract the transducer, turn the power off and check the ship’s mains voltage. It should be about 100 VAC.

Unretracted Transducer Warning

If the transducer is not completely retracted within 30 seconds after pressing c, an alarm sounds and the message XDCR NOT RETRACTED! appears at the screen center.

If this occurs, do the following:

1.The power cannot be turned off because the transducer can- not be retracted. Turn off the main breaker for the display and power supply units to stop operation.

2.Confirm that the net is not tangled in the transducer.

3.Confirm that the breaker inside the raise/lower control box (mounted on the hull unit) is on.

4.Remove the cover of the raise/lower control box. Push the (Red) reset button to reset the raise/lower control box.

5.Turn on the power and press c to retract the transducer into the tank. If it does not retract, the main shaft of the hull unit may be bent. Turn off the power and manually raise the trans- ducer up to the highest position by using the hand crank. (See the illustration on the next page.)

MODEL CSH-73 specifications

The Furuno MODEL CSH-73 is a cutting-edge marine radar that embodies innovative technology and exceptional performance, designed specifically for commercial vessels and professional mariners. This model represents a significant advancement in radar capabilities, enhancing both navigational safety and operational efficiency.

One of the standout features of the CSH-73 is its compact design paired with a high-resolution display. The radar boasts a 12.1-inch color LCD screen that provides a crisp and clear view, allowing operators to easily identify targets and navigate in challenging conditions. The intuitive user interface facilitates quick access to essential radar functions, making it user-friendly even for those who may not be experts in radar operation.

A notable technological advancement in the CSH-73 is its digital signal processing (DSP) technology, which dramatically improves target detection capabilities, especially in adverse weather conditions. This technology helps to filter out noise and clutter, enabling the radar to provide accurate readings and reliable targeting information. The advanced target tracking capabilities allow users to monitor multiple vessels simultaneously, enhancing situational awareness.

In addition to its impressive detection capabilities, the CSH-73 features an Automatic Radar Plotting Aid (ARPA), which aids in collision avoidance by tracking the course and speed of approaching vessels. This sophisticated system simplifies decision-making for the crew, promoting safer navigation.

Another key innovation is the integration of Ethernet and NMEA 2000 connectivity. This feature enables seamless integration with other onboard systems, such as chart plotters and autopilots, creating a comprehensive navigation network. This connectivity allows for real-time data sharing, which enhances the overall operational effectiveness of the vessel.

The CSH-73 is also equipped with a range of customizable settings, allowing mariners to tailor the radar display to their specific needs and preferences. Features such as adjustable gain, sea clutter, and rain clutter suppression enhance the radar's performance under various environmental conditions.

Constructed with durability in mind, the CSH-73 adheres to robust marine standards, ensuring reliable performance even in the harshest maritime environments. This resilience is crucial for commercial vessels that regularly operate in challenging conditions.

In summary, the Furuno MODEL CSH-73 stands out as a powerful tool for enhancing maritime safety and navigation. Its advanced technologies, user-friendly interface, and durable construction make it an essential component for modern vessels, providing mariners with the confidence they need to operate effectively in any navigational scenario. The CSH-73 continues to uphold Furuno's reputation for excellence in marine electronics, making it a trusted choice for professionals worldwide.
