Overview: The document provides a classification of marine commercial grade portable devices, focusing on both intrinsically safe and non-intrinsically safe models. These devices are categorized under different series such as HT, DX, DX-IS, and DTEx, and are intended for use on vessels registered within and outside the European Union (EU).

Specifications: The devices are divided based on their frequency bands (UHF and VHF) and display capabilities (display and non-display models). For EU registered vessels, the models include HT783M, DX485M, DT885M, DT985M, DT885FF, DT985FF for UHF display, and HT782M, DX482M, DT882M, DT982M for non-display. VHF models include HT644, DT844, DT944, DT844FF, DT944FF for display, and DT842, DT942 for non-display.

Non-EU Vessels: For vessels registered outside the EU, the UHF display models are DX585M-IS and DT585M, with non-display models being DX582M-IS and DT582M. VHF display models include DX544-IS and DT544, while non-display models are DX542-IS and DT542.

Safety Standards: The document highlights the intrinsic safety classifications, with devices categorized under IIB and IIC standards, indicating their suitability for different hazardous environments.
