10. ACCESSING CHANNELS SAVED TO MEMORY

Once channels have been saved, you can easily access them using the following procedure. Once in Memory mode, only the channels saved to memory will be accessible using the Up or Down Channel keys on the microphone handset or the CH/ENTER knob and the SCAN key on the radio base station.

To access saved channels:

1.Press and hold the HI/LOW/MEM key for 3 seconds, then release. The M icon will appear on the LCD to indicate that you are in Memory mode.

2.To scroll through saved channels, use the Up or Down Channel keys on the microphone handset or the CH/ENTER knob on the radio base station. To scan saved channels, press and release the SCAN key on the radio base station. For more information, see 12.Scanning.

3.Press the CANCEL/WX key or press and hold the HI/LOW/MEM key for 3 seconds and release to exit Memory mode and regain access to all channels.

11. USING THE TRANSMIT TIME-OUT TIMER (TOT)

When the Push-to-Talk (PTT) key on the microphone handset is held down, transmit time is limited to 5 minutes. This feature helps you to avoid unintentional transmissions. About 10 seconds before automatic transmitter shutdown, you will hear a warning beep from the speaker(s). When the Transmit Time-Out Timer takes effect, the VHF255S will automatically go into receive mode. Before transmitting again, you must release and then press the PTT key once again.

12. SCANNING

Scanning is an efficient way to locate incoming transmissions quickly over a wide selection of channels or from all the channels in a frequency band. Your Humminbird® VHF255S comes with two basic scan options, Normal and Memory Scan, with the ability to add Priority Scan to each of those modes:

•Normal Scan: If there are no channels in memory, the default mode will be Normal Scan. In Normal Scan mode, all channels in the band are scanned in sequence (for instance, 1,2, 3, 4...). After the last channel number in the band has been scanned, the sequence repeats. Normal Scan automatically and continuously searches for transmissions on the selected band. Pressing the Up/Down Channel keys on the microphone handset or turning the CH/ENTER knob on the radio base station (clockwise = up, counterclockwise = down) will change the scan direction. If a transmission (TX icon) is received, the scan stops

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.
