2. INSTALL THE RADIO BASE STATION

Mount the VHF255S radio base station on your vessel, using the mounting location determined in the previous procedure, and one of the two following procedures, gimbal mounting or recessed mounting.

NOTE: You have the option of gimbal bracket mounting, which can either be mounted on the dash or overhead and allows rotation of the radio during operation, or recessed mounting into a dashboard or other appropriate surface.

To install the radio base station using the regular gimbal mounting bracket:

1.Place the mounting bracket on the mounting surface and use a pencil to mark the location of the four holes in the bracket where the fasteners will be attached.

CAUTION: Before drilling, make sure that there is nothing behind the mounting surface that might be damaged while drilling the mounting holes.

2.Set the bracket aside, then drill four mounting holes at the marked locations. If you plan to use the supplied mounting screws, make sure the drill bit you use is slightly smaller than the screw diameter of the mounting screw. If you plan to use the supplied mounting nuts and bolts, make sure the drill bit you use is slightly larger than the diameter of the supplied bolt. Next, align the mounting bracket with the drilled holes, making sure that it is oriented correctly.

3.Insert each of the four supplied mounting fasteners through a spring washer, then through a flat washer, and then into the mounting holes. Secure the bracket to the mounting surface by tightening the mounting screws with a screwdriver or nutdriver, being careful not to overtighten the fasteners. If you are using the supplied mounting bolts, then you will need to hold the nuts on the backside of the mounting surface with a wrench while tightening the bolts with a screwdriver or nut driver, being careful not to overtighten the fasteners.

4.Mount the radio base station onto the bracket, making sure to match the protrusions on the inside of the two arms of the bracket with the indentations on the two sides of the radio base station.

5.Insert the supplied mounting knobs through the bracket arms and into the holes on each side of the radio. The gimbaled bracket allows you to loosen the knobs at each pivot in order to adjust the viewing angle of the radio and then to hold the selected viewing angle by tightening the knobs again.

NOTE: You should only tighten the knobs by hand.

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.
