Statement of differences between Remote Receiver Clock WS222 and WS220 Below is the comparison between the new model WS222 and the approved (PLJWS220) model WS220. Similarities • Both models share the identical plastic housing, keys • Both models utilize the same RF receiver module, located in the same orientation and location inside the plastic housing • Both models has the same construction of the internal receiver antenna • The operation duty cycle, operation frequency and modulation / bit rate are identical • The main processor circuit board has similar size and component layout • Both models operate on the same power source (2 x AA size battery) Differences • Minor differences in the pattern of LCD display due to different features • Different colour of plastic housing / keys

The same TX (WS260) is sold either with WS220 , WS240 or WS410. The radiated measurements were performed vertical, horizontal results are about 5 dB lower over the whole frequency range. All measurement settings are according to FCC 15.35, 15.205, 15.207, 15.209 and 15.231. Measurements below 1 GHz were performed with a CISPR Quasi Peak Adapter, over 1 GHz we used peak measurements. At peaks we did an second, average measurement. ResBW and VBW were according FCC requirements. No deviations from the technical specification(s) were ascertained in the course of the tests performed.
