A base site (110, 122, 114) has a base site transmitter (210) for communicating with a selective call receiver (108) and a base site receiver (214) for receiving an acknowledge-back signal from the selective call receiver (108). The selective call receiver (108) has a receiver (304) for receiving a signal from the base site (110, 122, 114), a decoder/controller (306) coupled to the receiver (304) for decoding the signal received from the base site transmitter (210), a status indicator(504) coupled to the decoder/controller (306) for indicating a predetermined status of a power supply for the selective call receiver (108). The selective call receiver (108) further has an acknowledge-back transmitter (334) coupled to the decoder/controller (306) for transmitting acknowledge-back signals to the base site (110, 122, 114) and an acknowledge-back suspension circuit (310) coupled to the acknowledge-back transmitter (334) for inhibiting transmissions of acknowledge-back signals in response to the status indicator (504).
