Entel HT644 VHF, geen ATIS is voorzien van de nieuwste intelligente lithium-ion batterijtechnologie. De socket is zo ontworpen dat de verbinding, wanneer deze aan de draagbare computer is bevestigd, bestand is tegen elke vorm van straf; van vallen tot onzorgvuldig misbruik. Om onbedoelde bediening te voorkomen, kunnen de toetsen en bedieningselementen van uw radio worden vergrendeld of, indien ingesteld, automatisch door de radio.
