PRE OWNED JRC JHS-183 JRC JHS-183 MARINE AIS

PRODUCT OVERVIEW

The JRC JHS-183 is an IMO-compliant Class-A AIS system that represents a significant leap in display technology and installation efficiency. Featuring a high-visibility 4.5-inch LCD with a specialized 50,000-hour lifespan, the JHS-183 is built for years of continuous 24/7 operation. Unlike older models, it consists of just two primary components connected by a single coax cable, making it the most popular choice for retrofitting vessels with modern, reliable AIS technology.

KEY FEATURES & APPLICATIONS

Simplified Two-Component Design: The system is comprised only of the display and the transponder. A single coax cable connects the two, drastically reducing installation time and potential cable failure points.

Dual-Color Backlight: The user can switch between a crisp white or a soft orange backlight, optimized for different bridge lighting conditions and reducing night-time eye fatigue.

Advanced Guard Zone Alert: Allows navigators to set a safety perimeter. The system triggers both a visual and audible alarm if any AIS-equipped vessel enters the zone.

AIS-SART Support: Automatically detects and prioritizes AIS-SART (Search and Rescue) signals, moving them to the top of the target list for immediate emergency response.

Flush-Mount Ready: The new design approach means no separate flush-mount kit is required; mounting screws are elegantly concealed behind the front cover for a clean bridge appearance.

Own-Group Recognition: Users can preset a list of "fellow ships" (company fleet or partner vessels), which are then displayed with unique symbols for instant identification.

Self-Diagnosis Function: A built-in automatic test suite monitors system health and signal integrity, ensuring the unit is always operating within SOLAS parameters.

TYPICAL CONDITION (USED/REFURBISHED)

System Set: Typically sold with the NCM-983 Controller and NTE-183 Transponder. (Note: The NQE-5183 Connection Box is an optional accessory and may not be included in all used sets).

Refurbishment Details: These units are highly durable. Refurbishment usually involves testing the 12.5W transmitter output and verifying the LCD backlight and contrast levels.

MMSI Clearance: Being a Class-A unit, it usually requires a password-protected reset to clear the previous vessel's MMSI.
