Common FeaturesA simple explanation of the IP rating system is writtenbelow. Please refer to more specialized informationmaterial if you wish to know more.An IP number contains two numbers (i.e. IP65) in mostinstances which relate to the level of protection providedby an enclosure or housing. Either number may beshown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part isnot tested.The first number relates to protection from solids asfollows:0: No special protection1: Protected against solid objects up to 50 mm indiameter2: Protected against solid objects up to 12 mm indiameter3: Protected against solid objects up to 2.5 mm indiameter4: Protected against solid objects up to 1 mm indiameter5: Dust protected6: Dust tightThe second number relates to protection from liquids asfollows:0: No special protection1: Protected against vertically falling drops of water2: Protected against direct sprays up to 15o from thevertical3: Protected against direct sprays up to 60o from thevertical4: Protected against sprays from all directions (limitedingress permitted)5: Protected against low pressure jets of water from alldirections (limited ingress permitted)6: Protected against strong jets of water e.g. for use onship decks (limited ingress permitted)7: Protected against the effects of temporary immersionbetween 15cm and 1m for 30min.8: Protected against long periods of immersion underpressure(Water-level and submersion time set bymanufacturer)7Enhanced audioThe IC-F3062 series employs a BTL (Bridged-Tied Loads) amplifier that increases the audio output and the built-in audio compander provides clear, low noisecommunications.IP55 Dust-protection and splash, water jet resistanceThe IC-F3062 series meets IP55 requirements for dust-protection, splash and water jet resistance. Its durableconstruction is backed up by the aluminum diecastchassis and polycarbonate casing, allowing reliableoperation under harsh weather and environmentalconditions.Standard MIL 810C MIL 810D MIL 810E MIL 810FMethod Proc.
