FUNCTIONAL DESCRIPTION

7.

Figure 3 shows the block diagram of the functional areas of the RPR 550IS Series.
Full circuit diagrams for the radio and main board of each type of pager appear in
Section 7.

Signal Processing

8.

The RF signal is detected by the antenna and fed to a single conversion
superheterodyne receiver where the RF is converted into IF and subsequently
demodulated into audio and data. The data is fed to the decoder circuit where the
memory, alert lamp, LCD, audible alert and vibrate alert (if fitted) are activated.
