Integrated AIS and GPS Receivers
A dual-channel AIS receiver monitors the position of nearby AIS-equipped vessels, helping you to avoid collisions in crowded harbours and waterways. AIS information can be viewed on the RS40's built-in screen, or overlaid on your chart or radar screen through a compatible multifunction display. An integrated GPS receiver ensures your boat's location can be sent with DSC distress calls, even if the rest of your on-board electronics are powered down.
Removable Fist Mic
The RS40's removable fist mic can be connected to the front or rear of the radio, and optional extension cables allow the radio and mic to be mounted separately. This offers a simple and cost-effective solution for any mounting location, with no cable clutter. For example, the RS40 can be mounted overhead, with no hanging cables, while the mic is connected to an extension socket on the dash below.
Expandable with Wireless Handsets
Add an optional wireless handset to take your radio anywhere on board. The HS40 handset was designed as an intuitive portable companion to the RS40. Each handset duplicates your radio's display and controls, enabling remote access to all key functions. Up to two wireless handsets can be connected to a single base station. With multiple handsets connected, the RS40 doubles as a handy on-board intercom.
***Minimum product requirements***
Requires a VHF antenna (sold separately). An external GPS antenna may be required in some installations. All DSC functions require an MMSI number issued by local authorities; charges may apply.
