PHCENIX CONTACT Wireless Interface RAD ISM 900 SET UD ANT One way Point to point Monitoring or Control User Manual The RAD ISM 900 SET UD ANT is a Frequency Hopping Spread Spectrum radio designed for the professional installation and integration with other products When installed with an approved antenna and cable the system integrator needs to make sure that the unit s FCC label or a copy of that FCC label is clearly visible on the outside of the integrated product The RAD ISM 900 SET UD ANT is approved within the 902 to 928 MHz ISM Band under Part 15 of the FCC Rules and Regulations Frequency hopping spread spectrum technology was originally developed by the U S military to prevent interference or interception of radio transmissions on the battlefield Frequency hopping devices concentrate their full power into a very narrow signal and randomly hop from one frequency to another within a designated frequency band If they encounter interference on a particular frequency the devices error check the affected data hop to another point on the spectrum and resume communications on subsequent hops Since there are always spaces without interference somewhere in the allotted radio spectrum a frequency hopping device will use those spaces to complete a transmission 929 NOTICE These devices must be wired in accordance with Class I Division 2 wiring methods as described in the National Electrical Code Article 50
