1. OPERATIONAL OVERVIEW

1.4Setting the Tilt Angle

The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, it is said to be zero (0) degrees and when emitted vertically, 90 degrees.

To set a tilt angle, operate the TILT lever for the desired angle while watching the tilt angle indication at the top right corner of the sonar display. Each time the lever is operated the newly selected tilt angle is displayed in large characters for five seconds at the top of the sonar display. The tilt angle can be set in one-degree steps within the range of 0 to 55 degrees.

1.4.1Automatic tilt on/off

The automatic tilt feature automatically tilts the transducer within the tilt range selected on the menu. This feature is useful for finding fish school center.

Automatic tilt becomes inoperative when the target lock feature is made active. Disable the target lock feature to resume automatic tilt.

1.Press the [MENU] key to open the menu.

2.Operate the [RANGE] control to choose [MENU MODE] at the top of the screen.

3.Operate the [GAIN] control to choose SONAR.

4.Operate the [RANGE] control to choose AUTO TILT.

5.Operate the [GAIN] control to choose ON.

6.Operate the [RANGE] control to choose TILT ANGLE.

7.Use the [GAIN] control to choose a tilt range among ±2-10°, ±4-14°, ±6-20°, and ±10-26°. See the table on the next page for range and tilt angle.

8.Press the [MENU] key to close the menu. When auto tilt is on, auto tilting begins with the range selected (at step 7), centered on the tilt angle set with the TILT lever.

To turn off automatic tilt, choose OFF at step 5. Note that automatic tilt range varies with the range in use.

CSH-5L/CSH-8L specifications

Furuno CSH-5L and CSH-8L are advanced marine radar systems known for their cutting-edge technology and user-friendly interfaces. Designed primarily for maritime applications, these radar units cater to a wide range of vessels, from commercial ships to fishing boats. The primary distinguishing feature of the CSH-5L and CSH-8L radar systems lies in their ability to provide high-resolution images and precise detection of targets, ensuring navigational safety and operational efficiency on the water.

One of the standout technologies incorporated into both models is the pulse compression technique. This feature significantly enhances target resolution and minimizes blind spots, allowing the radar to detect smaller objects at greater distances. With the CSH-5L and CSH-8L's powerful signal processing capabilities, users can expect exceptional performance even in challenging weather conditions, ensuring reliable operation during storms or fog.

The CSH-5L model operates at a frequency range of 5 GHz, while the CSH-8L uses an 8 GHz frequency. Both radars are equipped with a rotating antenna that provides a wide coverage range, allowing for efficient monitoring of the surrounding marine environment. Their high sensitivity and low noise levels enhance target detection, making them particularly useful for locating small fishing vessels or buoys.

Another important characteristic of the Furuno CSH-5L and CSH-8L is their user-friendly interfaces. Both models feature intuitive controls, allowing operators to adjust settings easily and access critical information quickly. The displays are designed for clarity, enabling users to distinguish between targets and navigate effectively.

Additionally, the radar systems include advanced features such as automatic target tracking and target acquisition capabilities. This functionality allows users to monitor multiple targets simultaneously, providing essential situational awareness for safe navigation. The CSH-5L and CSH-8L also support integration with other onboard systems, including ECDIS (Electronic Chart Display and Information System), which enhances the overall effectiveness of maritime navigation.

In summary, the Furuno CSH-5L and CSH-8L radar systems represent the forefront of marine radar technology, offering exceptional detection capabilities, user-friendly controls, and robust integration options. Their advanced features ensure that mariners can navigate confidently, making them a vital asset for anyone operating in the marine environment.
