4 ft, 4 kW Open Array Scanner MR-1220T4

---

FEATURES:

• 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.

• 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.

• Automatic Identification System (AIS) Overlay Function

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.

• External Buzzer Connection

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

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.
