Abstract
A pager (1) includes switches (12,13,14,15) for setting the priority of a message expected to be received at a predetermined time on a substantially continuous carrier signal. A receiver (3) is then activated for a period of time determined by the priority setting prior to the expected time of the message. The length of the period of time is greater for a higher priority setting so that if the carrier signal is not detected, an alert is indicated either visually (9) or audibly (10) giving the user time to place himself into range of the carrier signal. Furthermore, the pager (1) may operate in a reduced power mode prior to the predetermined time.
