In a communication unit a receiver (104) receives a modulated signal (118), and produces a received signal (120) having a parameter. The receiver (104) has a discontinuous receive mode of operation, wherein the receiver (104) is permitted to be turned on and off. Receiver circuitry (105) receives the received signal (120), and produces an output signal (124) having a parameter. A controller (110) adjusts a value of the parameter of the output signal (124), responsive to a value of the parameter of the received signal (120), during the times when the receiver (140) is turned on; and holds the value of the parameter of the output signal (124), responsive to the value of the parameter of the received signal (120), at the time when the receiver (104) is turned off. The present invention advantageously minimizes the turn on time for the receiver (104) operating in a discontinuous receive mode to save current drain.
