Hytera Two-way Radio PD790 Ex

technical highlights
improved pcb circuit layout & emc shielding
to achieve such a high safety standard, hytera pd790exadoptsoptimized distributed line design on pcb, minimizing theoddsofcircuit fault. all the key components on the pcb arecoveredwithshield, and the space between lines, betweencomponents,betweencomponent and shield are properly spaced , whichtranslatestobetter emc performance and less internalinterference.
innovative silicone encapsulating
silicone encapsulant technology prevents the internalcircuitsfrominterface with air and liquid which effectively stopstheintrusionof liquid, dust and harmful gas. thesiliconeencapsulating processis delicate and complicated. as aresult,every single pd790 exradio spends eight hours in themanufactureline.
innovative electrostatic free design
hytera applies patent on electrostatic free designanddual-materialmolding technology in this intrinsicallysafeportable. the staticdispersive material (blue) minimizesstaticaccumulation on thesurface, thus reducing the probabilityofstatic discharge on theradio. meanwhile the robustmaterial(black) maximizes theruggedness of the enclosure.
ip67 (non-explosion-proof)
the ingress protection reaches ip67 (6: totallyprotectedagainstdust; 7: protected against the effects of immersionup to 1mfor 30minutes). it\'s the highest ip level for land-basedwirelessradioapplication.
patented battery latch
to disengage the battery from hytera digital portables, thelockandbolt of the latch need to be moved along two differentaxes.such apatented design ensures no disengagement of the batterypackfromthe main radio in case of dropping that might causespark.
certification
atex is the european union directive to which all two-wayradiosmustconform if used in potentially explosive environments.itreplacesthe cenelec classification in all european unionmemberstates andefta countries.
iecex scheme is the future route to globalcompliancecertification.its aim is to harmonize standards to allowfreemovement of goods byestablishing a world-wideacceptedstandard.
fm (fm approvals llc) is a member of nationallyrecognizedtestinglaboratories of u.s.a. it strives to offer globalserviceswithunsurpassed technical integrity andexceptionalcustomersatisfaction.
applications
chemical industry
flammable gases, liquids and solids are converted andprocessedinmany different processes in the chemical industry.theseprocessesmay give rise to explosive mixtures.
power generating companies
lump coal, which is not explosive in mixture with air,maybeconverted in the conveying, grinding and drying processesintocoaldusts capable of forming explosive dust/air mixtures.
mining
the by-product of coal mining is gas. following thecoalexploiting,the gas will gather under the ground. if not ingoodsecuritymanagement, gas in coal mine can lead to seriousgasexplosion.
fire fighting 
as for fire fighting, some task critical situations such asoilspillor natural gas leakage need high securityelectricalequipments.
pharmaceutical industry
alcohols are often used as solvents in theproductionofpharmaceuticals. agents and auxiliary materials thatgive risetodust explosions, such as lactose, may also be used.
refineries 
the hydrocarbons handled in refineries are allflammableand,depending on their flash point, may give risetoexplosiveatmospheres even at ambient temperature. the areaaroundoilprocessing plant is generally regarded as a placewhereexplosiveatmospheres may occur.
