  • Page 35 RPR 583 The RF signal enters the aerial and is fed to the dual conversion superheterodyne receiver. The signal is demodulated from RF to baseband frequencies, converted to digital format and is then fed to the decoder. This results in the received data activating the memory, display and the selected audible alert or vibrate alert.
