ABSTRACT:
A pager receiver for receiving signals transmitted in the POCSAG code format which includes a preamble signal followed by at least one batch, the pager receiver including a preamble absence detector circuit for detecting whether or not a received signal includes the preamble and a power saving circuit responsive to the preamble absence detector circuit for deactivating signal processing circuits of the pager receiver as soon as detection is made that the received signal does not include the preamble signal. The power saving circuit causes the signal processing circuits of the pager receiver to operate in a low power mode in which the signal processing circuits are deactivated for an extended period of time, such as for 256 seconds, when a received signal includes an inverted synchronizing signal following the last codeword transmitted, the signal processing circuits being maintained in the low power mode in response to a received signal which includes the preamble signal followed immediately by an inverted synchronizing signal.
