The sailor range of radios support crews in safe and efficient operations as well as meeting GMDSS international safety regulations. Designed to withstand the tough maritime environment while coping with the demand for reliable communication and safety equipment at sea, RT5022 VHF DSC class A aims to make history into the future.
It is a vital tool for everyday operation and has been developed for the harsh maritime environment. RT5022 VHF DSC provides flexibility through straightforward installation, either as part of a GMDSS console or on its own. As a result of improved, high performance and innovative, easy-to-use functionality the radio offers important operational enhancements. It introduces two separate displays and menus, so that the user can easily change settings. The highly advanced 7 segment LCD display ensures the information can be read regardless of the light conditions on the bridge – day or night. The text can be displayed as white on black background, and as black on white background, to provide the optimal reading condition in daylight. Red backlight protects the night vision of the user.
