Setup and Installation
Proper installation is crucial for the optimal performance of your MR-1010R2 radar system. It is recommended that installation be performed by a qualified marine electronics technician.
1. Mounting the Radome Antenna
- Choose a mounting location that provides an unobstructed 360-degree view of the horizon. Avoid areas where the radar beam could be blocked by masts, antennas, or other structures.
- Ensure the mounting surface is strong enough to support the weight of the radome (approximately 26.3 kg) and withstand marine conditions.
- Use the provided installation hardware to securely fasten the radome.
2. Mounting the Display Unit
- Select a location in the cockpit or cabin that is easily accessible and visible to the operator, away from direct sunlight if possible.
- Ensure adequate ventilation around the unit.
- Mount the display unit using the supplied bracket, allowing for adjustment of the viewing angle.
3. Wiring and Connections
- Connect the 15-meter interconnect cable between the radome antenna and the display unit. Ensure connections are secure and waterproof.
- Connect the power cable to a DC power source (10.2-42V). Observe correct polarity.
- For advanced features, connect the MR-1010R2 to compatible external devices:
- DSC Radio: Connect to a DSC radio to enable the DSC information function and plot received DSC messages.
- External AIS Device: Connect to an AIS device (e.g., ICOM M506, M605) to enable AIS overlay on the radar display.
- Refer to the detailed wiring diagrams in the full installation manual for specific connection points.
Operating Instructions
This section outlines the basic operation of the ICOM MR-1010R2 Marine Radar.
1. Powering On and Basic Display
- Press the power button to turn on the unit. The system will perform a self-test.
- The color RFT LCD (480x640 dots) display will show radar echoes with 16 steps gradient intensity.
- Use the "BRILL" button to easily adjust the screen color settings (Day, Night, and User settings) for optimal visibility in various lighting conditions.
- The auto hide information function can be activated to enlarge radar echoes by temporarily hiding non-essential information.
2. Navigation and Menu Operation
- The large eight-direction cursor key provides smooth navigation through menus and settings, even when wearing gloves.
- Configure various settings through the MR-1010R2's visually intuitive operation.
- The language setting is selectable from English, Indonesian, Korean, Spanish, Thai, and Vietnamese.
3. Advanced Radar Functions
- ARPA Function: Utilize the simplified ARPA (Automatic Radar Plotting Aid) function to track other vessels or objects and assess collision risk.
- TLL Function: Use the Target Latitude Longitude (TLL) function for precise tracking and plotting of specific targets.
- True Trail Function: Activate the true trail function to display the true movement of targets relative to your vessel.
- Alarm Zones: Set up to two user programmable alarm zones to be alerted to targets entering specific areas.
4. Integration with External Devices
- DSC Information Function: When connected to a DSC radio, received DSC messages are transferred to the MR-1010R2. You can plot up to 20 DSC messages directly on the radar echo.
- MOB Waypoint Display: If a Man Overboard (MOB) position information is transmitted from a DSC handheld transceiver (e.g., ICOM M93D), the MR-1010R2 can show the MOB waypoint on the radar echo to assist in search and rescue operations.
- AIS Overlay Function: When connected to an external AIS device (e.g., ICOM M506 & M605), up to 100 AIS target icons can be overlaid on the radar echo. Selecting an AIS icon displays vessel information such as AIS class, MMSI number, vessel name, course, speed, CPA (Closest Point of Approach), TCPA (Time to Closest Point of Approach), bearing, and distance on the lower side of the display.
Maintenance
Regular maintenance ensures the longevity and reliable performance of your MR-1010R2 radar system.
- Cleaning: Regularly clean the display screen and the exterior of the radome with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the surfaces.
- Connections: Periodically check all cable connections for corrosion or looseness. Ensure waterproof seals are intact.
- Radome Inspection: Inspect the radome for any physical damage, cracks, or signs of water ingress.
- Software Updates: Check the ICOM website periodically for any available software or firmware updates for your MR-1010R2.
- Professional Inspection: Consider having the system professionally inspected and serviced annually, especially if operating in harsh marine environments.
Troubleshooting
This section provides solutions to common issues you might encounter. For more complex problems, contact ICOM support or a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to display unit. | Loose power connection, blown fuse, insufficient voltage. | Check power cable connections. Inspect and replace fuse if necessary. Verify power source voltage (10.2-42V DC). |
| No radar echoes or weak echoes. | Radome cable disconnected, antenna obstruction, incorrect gain/clutter settings. | Ensure interconnect cable is securely connected. Check for physical obstructions to the radome. Adjust gain, sea clutter, and rain clutter settings. |
| Display is dim or unreadable. | Brightness setting too low, direct sunlight. | Adjust display brightness using the appropriate controls. Use the "BRILL" button to switch display modes (Day/Night). Reposition unit if possible to avoid direct sunlight. |
| AIS/DSC data not displayed. | Incorrect wiring to external device, external device not powered on, incorrect settings. | Verify connections to DSC radio or AIS device. Ensure external devices are powered on and transmitting data. Check radar unit settings for AIS/DSC overlay activation. |
