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.

Simplified ARPA
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.

Received DSC example
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.

Marine Radars MR-1220 / MR-1010RII Introduction



Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.


Degrees of Solid Particle Protection – 1st Digit
IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
---|---|
IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
---|---|
IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
IPx4 | Protected against water splashed against the equipment from any direction |
