The Standard Horizon Quantum GX5500S meets the requirements for Class D with a separate Channel 70 receiver, which allows DSC calls to be received even when listening to traffic on Marine VHF channels.
The DSC DISTRESS function when activated transmits a digital MAYDAY including vessel identification, Latitude / Longitude and time (with GPS connected), to facilitate prompt response. Additional calls that can be made are Individual, Urgency and Safety.
If the GX5500S fails for any reason (including water damage) during normal use for the first 3 years of ownership, STANDARD HORIZON will repair or replace it free, without hassles or charges. If it fails for anytime thereafter in normal use, for as long as the original purchaser owns the radio, STANDARD Horizon’s Lifetime Flat Rate and Customer Loyalty Service Programs will cover it.
