DSC Call Types

LAST CALL: Recalls last call regardless of which type of call was received last.

NEW CALL: Allows you to make a new call, either by entering an MMSI number

or by selecting a number from the Contact List.

GROUP: Sends transmissions that are only received by radios that share a common group MMSI number; up to 3 group MMSI numbers can be stored and called.

ALL SHIPS: Make an Urgency, Safety, or Routine call to all DSC-enabled ships or ships within communication range. A re-confirmation screen will be displayed after you choose one of these three call types. You should send an All Ships call when assistance is needed but the situation is not serious enough for a Distress Call. An Urgency call is made when assistance is required but the situation is not life- threatening, while a Safety call is for an advisory alert.

CALL LOG: Allows a review of the last 20 stored calls by number and time of call. An individual call type can be placed to the selected MMSI/NAME in the LOG. The LOG maintains all received call types except DISTRESS calls. The earliest call is stored at the end of the list (20 maximum), and is automatically erased when a new call comes in.

DISTRESS LOG: Allows a review of the last 10 stored Distress calls by number and time of call. The earliest call is stored at the end of the list (10 maximum), and is automatically erased when a new call comes in.

POS REQUEST: Allows you to request GPS position information from any vessel for which an MMSI number is known; you can either pick the MMSI number of the vessel from the Contact List, which is a personal DSC directory of saved MMSIs, or by manual entry.

EXIT: Quits the DSC Call Type menu mode.

VHF255S, VHF255SW specifications

The Humminbird VHF255SW is an advanced VHF marine radio designed for reliability and performance on the water. It is built for recreational boaters, offering a combination of essential features and cutting-edge technologies that enhance communication and navigation safety.

One of the standout features of the VHF255SW is its robust 25-watt output power, which provides extended range communication, allowing users to reach distant vessels and shore stations effectively. This high power output is crucial in emergency situations or when out on open water, ensuring that skippers can maintain contact when it matters most.

The radio is equipped with a built-in Class D Digital Selective Calling (DSC) capability, which is designed to enhance safety. This feature allows users to send a distress signal automatically to the coast guard and other vessels within the vicinity, including their location coordinates. The DSC functionality can be a lifesaver in case of an emergency, providing peace of mind for boaters.

Another key characteristic of the VHF255SW is its large, high-contrast LCD display, which is easy to read even in bright sunlight or at night. The multi-color display features adjustable backlighting, ensuring users can navigate and communicate effectively in various lighting conditions. The intuitive user interface simplifies operation, making it accessible for even the most novice boater.

Additionally, the Humminbird VHF255SW is equipped with a built-in GPS receiver, which allows for enhanced positioning and mapping capabilities. This integration enables users to access real-time information, making navigation smoother and more efficient. The unit also supports navigating to specific waypoints and routes, making it an excellent tool for fishing and exploring new waters.

The radio is designed with a rugged, waterproof housing that meets IPX7 standards, meaning it can withstand submersion in water for short periods. This durability ensures that it operates reliably in rough marine conditions. The Humminbird VHF255SW also features a noise-canceling microphone for clearer communication, minimizing background noise during transmissions.

In summary, the Humminbird VHF255SW blends important marine communication capabilities with advanced technology. Its combination of high output power, DSC functionality, built-in GPS, and a user-friendly interface makes it an invaluable asset for any boating enthusiast, ensuring safety and confidence on the water. With its rugged design and reliability, the VHF255SW is a smart choice for those who demand quality and performance from their marine radio.
