5.3 TRANSMISSION

NOTE

Never key the transceiver without an antenna connected, as this may cause damage to the transceiver.

1.Perform steps 1 through 7 of the RECEPTION discussion above.

2.Before transmitting, monitor the channel and make sure it is clear.

THIS IS AN FCC REQUIREMENT!

3.For communications over short distances, press the H/L key until “” is displayed on the LCD. This indicates Low power (approximately 1 Watt).

NOTE

Transmitting on 1 Watt prolongs battery life. Low power (1 Watt) should be selected whenever possible.

4. If using Low power is not effective, select Medium power (2.5 Watts) or High power (5 Watts) by pressing the H/L key until

“ ” (Medium power) or “ ” (High power) is dis- played.

5.When receiving a signal, wait until the incoming signal stops before trans- mitting. The transceiver cannot transmit and receive simultaneously.

6.Press the PTT (Push-To-Talk) switch to transmit. The “TX” indicator is displayed during transmission.

7.Speak slowly and clearly into the microphone. Hold the microphone about ½ to 1 inch away from your mouth.

8.When the transmission is finished, release the PTT switch.

5.4 TRANSMIT TIME - OUT TIMER (TOT)

While the PTT switch is held down, transmission time is limited to 5 minutes. This prevents prolonged (unintentional) transmissions. About 10 seconds before automatic transmitter shutdown, a warning beep sounds from the speaker. The transceiver automatically switches to the receiving mode, even if the PTT switch is held down. Before transmitting again, the PTT switch must first be released, then pressed again. This Time-Out Timer (TOT) pre- vents a continuous transmission that would result from an accidentally stuck PTT switch.

HX270S specifications

The Standard Horizon HX270S is a versatile and robust handheld VHF marine transceiver designed to meet the communication needs of boaters and marine professionals. Renowned for its durability and comprehensive features, this device is a vital tool for enhancing safety and connectivity on the water.

One of the standout features of the HX270S is its impressive waterproof rating of IPX7, which ensures that the radio can withstand immersion in water up to 1 meter for 30 minutes. This resilience makes it suitable for use in rough marine environments. Additionally, the radio is built to endure bumps and drops, making it a reliable companion for outdoor excursions.

The HX270S is equipped with a powerful 6W output, allowing for extended communication range under ideal conditions. This increased output power is complemented by an impressive battery life, with a 1650mAh lithium-ion battery providing up to 12 hours of continuous use. Users can easily monitor battery status and receive low battery alerts, ensuring they stay connected when it matters most.

The device features a large, easy-to-read LCD display that provides essential information, including channel numbers, battery life, and signal strength. The intuitive control layout allows users to access functions quickly, including the dual-watch feature, which allows monitoring of two channels simultaneously—ideal for listening to distress channels while communicating on another frequency.

The HX270S supports the latest digital selective calling (DSC) technology, which offers automated distress signaling capabilities. This feature enhances safety by automatically sending out a distress signal with the boat’s GPS coordinates to nearby vessels and coast guard stations when the emergency button is pressed. Additionally, it can receive DSC calls, allowing for critical communication in emergencies.

Another significant feature of the HX270S is its built-in GPS receiver, which provides accurate positioning information and can be used to mark waypoints or locations of interest on the water. This integration with GPS technology enhances navigational safety, as users can communicate their precise location in emergencies.

Furthermore, the HX270S offers compatibility with both USA, International, and Canadian Channels, providing a wide range of frequencies for diverse marine communication needs. The radio also includes programmable memory channels, allowing users to save frequently used channels for quick access.

Overall, the Standard Horizon HX270S is a well-rounded marine VHF radio that combines durability, advanced technology, and user-friendly features. It provides boaters with the assurance of reliable communication, crucial for safety and coordination on the water. Whether for recreational or professional use, the HX270S is a commendable choice for any maritime enthusiast.
