It meets the stringent requirements of SOLAS Chapter II-2, essential for marine vessel safety, and holds CE, FCC, and ISO 9001 certifications, demonstrating adherence to international quality and safety standards. This comprehensive certification suite ensures the A300U is readily deployable in diverse maritime and industrial settings worldwide, meeting regulatory requirements and providing assurance of product quality and safety.
   
• Versatile Functionality: PC Programmable & Advanced Audio Features. Beyond essential safety and communication features, the A300U offers advanced functionality for enhanced team coordination. PC programmability allows for customized channel configurations and feature settings to match specific operational needs. Support for 50 groups of analog CTCSS and 105 groups of digital DCS sub-audio frequencies enables flexible communication grouping and minimizes interference from other radio systems, ensuring clear and focused team communication.

 

Accessory Combinations: T88 Throat Mic & S88 Bone Conduction Headset for Specialized Applications
 

To further enhance the A300U's versatility and performance across diverse hazardous environments, HZH Marine offers specialized headset accessories: the Ocean One T88 Throat Microphone Headset and the Ocean One S88 Bone Conduction Headset. These headsets are designed to optimize communication in specific challenging scenarios.

Ocean One T88 Throat Microphone Headset:

• Key Features: Utilizing throat vibration conduction technology, the T88 headset picks up speech directly from throat vibrations, effectively isolating speech from loud ambient noise. This hands-free design allows for unencumbered operation in demanding tasks.
• Ideal Applications:
  • Fire and Rescue Operations: Essential for communication in smoke-filled environments where firefighters require respiratory masks. The T88 works effectively even with breathing apparatus, ensuring clear communication amidst roaring flames and smoke.
  • High-Altitude Maintenance: Ideal for rope access technicians and high-rise maintenance crews who need both hands free for work while maintaining constant communication.
  • Noisy Marine Engine Rooms: Perfect for engine room personnel working in extremely loud environments where conventional headsets struggle to overcome engine noise. The T88 ensures clear communication even amidst deafening machinery.
     

Ocean One S88 Bone Conduction Headset:

• Key Features: Featuring a lightweight design and an omnidirectional microphone, the S88 bone conduction headset transmits audio through bone vibrations directly to the inner ear, leaving the ear canal open and comfortable for extended wear.
• Ideal Applications:
  • Port Dispatch and Logistics: Suited for port dispatchers and harbor control personnel who require clear communication for extended periods while maintaining awareness of surrounding sounds in busy port environments.
  • Chemical Plant Inspections: Ideal for plant inspection teams requiring rapid response communication while remaining alert to environmental changes and potential hazards within the plant.
  • Emergency Command Centers: Excellent for emergency response teams and command center staff needing clear team communication and coordination during fast-paced, collaborative operations.
