SR303 Survival Radio VHF Multi-Channel GMDSS/FCC/MED with Replaceable Lithium Ion Battery

The ACR Electronics SR303 Marine GMDSS VHF Radio is built with flexibility in mind, offering users convenient options to facilitate communication at sea regardless of the circumstances. Designed as a GMDSS (Global Maritime Distress and Safety System) product, this waterproof VHF radio is fully certified to meet IMO and SOLAS regulations and seamlessly provides essential communication support in both critical situations and during everyday routine maritime operations. 

Offered in two convenient formats, as solely a GMDSS Emergency VHF for emergency use only applications or as a full kit for general-purpose everyday use and/or emergency use applications, the ACR Electronics SR303 radio serves as an all-encompassing solution for all your maritime communication needs. 

The GMDSS Emergency VHF comes with a primary Lithium battery, which includes a battery witness label so that there is never any question as to whether the primary battery has been used or not. Once the witness label is removed, the radio will auto power on when the battery is connected, and the unit will also automatically enter GMDSS operation mode with the following preset settings: channel 16, volume level 8, and squelch set to 2.

The full kit includes the primary Lithium battery as described and also comes with a Lithium-ion rechargeable battery, a charging base, and a mains to 12V supply plug. Standard accessories supplied with both the standalone GMDSS Emergency VHF option and the full kit option include a flexible rubber antenna, belt clip, and wrist lanyard.

Built with ease of use as a design priority, the SR303 is suitable for operation while wearing survival suit gloves and features an easy-to-read digital display. Both the display and keypad are backlit, making operation in low-light environments simple. The SR303 also includes NFC (Near Field Communication), allowing access to battery replacement date and product information on a mobile device.     

The durable design of the SR303 makes it suitable for all marine applications and an ideal choice for mandatory and voluntary carriage. With significant experience in marine safety technology and an ongoing commitment to quality and innovation, the ACR Electronics SR303 Marine GMDSS VHF Radio delivers the type of unparalleled performance that mariners worldwide have come to expect from all products produced by ACR Electronics.

FAQs

Please read our FAQs page to find out more.

When will my order ship?

For in-stock items, orders placed by 4:00 PM EST are eligible to ship the same day. If any item in the order is not currently in stock, shipment timing will depend on availability.

What is your return window?

Eligible merchandise may be returned within 30 days from the date of receipt. All returns require a Return Merchandise Authorization (RMA) number before anything is sent back. For the smoothest experience, we ask customers to contact Salina Vita first so we can coordinate the request properly. Returned merchandise must be complete, in its original packaging, and in resalable condition. Items that arrive incomplete, improperly packed, or not suitable for resale may not qualify for return approval.

Are restocking fees possible?

Yes. Approved returns may be subject to a restocking fee of up to 15%. Non-stock items may not be returned. In addition, opened or unsealed DVDs, CDs, and cartography products are non-returnable unless defective. If the product falls into CWR’s excluded media categories—such as opened or unsealed cartography, DVDs, or CDs—it is not returnable unless defective.

If my unit needs warranty service, should I send it back to Salina Vita?

No. Units requiring service, whether under warranty or otherwise, should be returned directly to the appropriate manufacturer, not to Salina Vita. We are always happy to help guide you to the correct manufacturer support path. Absolutely. While the service destination is the manufacturer, we can help you identify the proper support channel and make the process feel more straightforward and well-managed. Units that require service themselves, however, should go directly to the manufacturer under CWR’s policy.

I still have more Questions, can we contact you?

At Salina Vita, we believe premium marine commerce should feel measured, transparent, and reassuring. If you have a question about a shipment, return eligibility, or manufacturer service, contact us before taking the next step and we will guide you with the discretion and clarity your vessel deserves.
