Simplified Automatic Radar Plotting Aids (ARPA) Function

The simplified ARPA function*1 *2 assists you to prevent your vessel from colliding with other vessels or objects. When a target enters the preset watch area, it is automatically tracked on the radar echo. By selecting one of the targets, the target information, such as position, course, speed, CPA (Closest Point of Approach), TCPA (Time to CPA), bearing, and distance is displayed. When a target enters the CPA, or it exceeds the set TCPA, an alarm sounds to warn you.

Digital Selective Calling (DSC) Information Display function

When connected to a DSC radio and a DSC call is received, the received message is displayed on the MR-1220*1. The function shows the DSC message, and the location where the DSC call is transmitted. Up to 20 DSC messages can be plotted. A Man Overboard waypoint can also be displayed.

Automatic Identification System (AIS) Overlay Function

Compatible Icom marine DSC
radio example,IC-M605

When connected to an external AIS device (including Icom IC-M605 and IC-M506 AIS), up to 100 AIS target icons are overlaid on the radar echo*1. By selecting an AIS icon, vessel information such as AIS class, MMSI number, vessel name, course, speed, CPA, TCPA, bearing, and distance is displayed.

External Buzzer Connection

On the deck

The MR-1220 has an external buzzer terminal on the rear panel. You can sound an alarm beeper to effectively inform of danger, when a target enters the CPA or it exceeds the TCPA*3.

Plot Function

Plot function example

The Plot function*1 records your vessel's longitude and latitude at the set time interval, and displays your track on the radar echo.

3D Display Function

The MR-1220 provides an intuitive bird's-eye view. You can change the display angle according to your own preference. The 2D view can be displayed at the same time.

Multi-Lingual User Interface
