6.5Mode and Length of Vectors

True or relative vector (vector mode)

Target vectors are displayed relative to own ships reading (Relative) or with reference to North (True). Own ship does not have a vec- tor in relative mode.

Vector length

From the ARP-10 MENU, Vector Length can be set to 30 seconds, 1, 3, 6, 15 or 30 min- utes and the selected vector time is indicated on the screen.

The vector tip shows an estimated position of the target after the selected vector time elapses. It can be valuable to extend the vec- tor length to evaluate the risk of collision with any target.

6.6 Past Position Display

The Auto Plotter displays equally time-spaced dots (maximum five dots) marking the past positions of any targets being tracked.

If a target changes its speed, the spacing will be uneven. If it changes course, its plotted course will not be a straight line inTM mode.

To turn past position display an or off do the following:

1.Open the ARP-10 menu.

2.Select History.

3.Select plot enterval among 15, 30 sec- onds, 1, 2, 3 or 6 minutes. Select OFF to erose the past position display.

4.Press the [ACQ/ENTER] key.

5.Press the [MENU] key.

6.7 Operational Warnings

There are two main situations which cause the ARP-10 to trigger visual and audible alarms:

CPA/TCPA alarm

Lost target alarm

CPA/TCPA alarm

CAUTION

The CPA/TCPA alarm feature should never be relied upon as a sole means for detecting the risk of collision.

The navigator is not relieved of the responsibility to keep visual lookout for avoiding collisions, whether or not the radar or other plotting aid is in use.

Visual and audible alarm are generated when the predicted CP A and TCPA of any target become less than their preset limits.The au- dible alarm continues for 10 seconds.

The ARP-10 continuously monitors the pre- dicted range at the Closest Point ofApproach (CPA) and predicted time to CPA (TCPA) of each tracked target to own ship.

When the predicted CP A of any target be- comes smaller than a preset CPA alarm range and its predicted TCPA less than a preset TCPA alarm limit, the ARP-10 releases an audible alarm. In addition, the target plot sym- bol changes to a triangle and flashes together with its vector. The flashing of the triangle plot symbol and vector remain on the screen un- til the dangerous situation is no longer present or you intentionally terminate tracking of the target by using the [SELECT/CANCEL] key.

Provided that this feature is used correctly, it will help prevent the risk of collision by alert- ing you to threatening targets. It is important that GAIN, A/C SEA, A/C RAIN and other radar controls are properly adjusted and the Auto Plotter is set up so that it can track tar- gets effectively.

1932 MARK-2 specifications

The Furuno 1932 MARK-2 is a state-of-the-art radar system designed for maritime applications, providing exceptional performance and reliability. This advanced radar unit is renowned for its impressive range, superior target detection capabilities, and user-friendly interface, making it an essential tool for vessels of all sizes.

One of the standout features of the Furuno 1932 MARK-2 is its high-resolution display. The 10.4-inch color LCD screen offers crystal-clear visuals, enabling mariners to easily interpret radar data. With the capability to display 16 different colors, users can customize their views for enhanced clarity, allowing for better discrimination between targets and clutter. Additionally, the unit incorporates adjustable gain and clutter control, giving operators the ability to fine-tune the radar image to suit varying conditions, whether in busy harbors or open waters.

The 1932 MARK-2 utilizes a powerful 2.2 kW magnetron, allowing for excellent range performance. It can effectively detect targets up to 36 nautical miles away, providing mariners with ample warning of potential hazards. This long-range capability is complemented by advanced target tracking technologies, including ARPA (Automatic Radar Plotting Aid). This system enables users to monitor and track multiple vessels simultaneously, providing essential information such as course, speed, and distance for better situational awareness.

In terms of technology, the Furuno 1932 MARK-2 includes a Fast Target Update feature. This allows for rapid refresh rates, ensuring that moving targets are accurately displayed, even in heavy traffic areas. The unit also employs advanced digital signal processing to filter out noise and improve target detection, enhancing overall operational efficiency.

Another key characteristic of the 1932 MARK-2 is its robust build quality. Designed to withstand the marine environment, the unit features a waterproof casing with an IP55 rating, ensuring durability against splashes and humidity. Furthermore, its compact design offers versatile mounting options, making it adaptable for various vessel configurations.

Overall, the Furuno 1932 MARK-2 radar system stands out for its blend of advanced technology, user-centric features, and rugged reliability. Its ability to provide clear and accurate radar imagery makes it an invaluable asset for navigators, enhancing safety and efficiency on the water. As an investment in maritime technology, it offers significant advantages to enhance both recreational and commercial navigation.
