Abstract
In a selective call radio paging device, a plurality of alerts are generated in response to the decoding of a message having an address corresponding to the address assigned to the pager. A specific alert envelope waveform is generated and drives an alerting device of a first type (e.g., a transducer). Inverting means is provided to invert the envelope and cause a second alerting device (e.g., visual) to be activated in a manner complementary to the first. Thus, alerting devices are not operated concurrently, and peak loads on a resident power source are avoided.
