The ACR Electronics SR303 is a GMDSS-certified, multi-channel VHF radio engineered to meet IMO and SOLAS standards for both emergency and everyday maritime communication. The primary lithium battery includes a tamper-evident witness label — once removed, the radio auto-powers on and enters GMDSS mode preset to channel 16, volume 8, and squelch 2. The full Survival Radio Kit adds a rechargeable lithium-ion battery, charging base, and mains-to-12V supply plug. Large, glove-friendly controls pair with a backlit display and keypad for reliable low-light operation, while built-in NFC lets you pull battery replacement dates and product info directly to a mobile device. All configurations include a flexible rubber antenna, belt clip, and wrist lanyard.
