HT940 ATIS, ATEX approved intrinsically safe radio

Submersible - The unique and advanced HT900 Series conforms to all aspects of the European ATEX Directive. It further exceeds the ATEX requirements by being completely submersible - all other radios in this class are merely splash-proof. Entel believes that non-submersible radios have no place in the harsh world of maritime and terrestrial high-risk environments.
