A mobile telephone has a high frequency system clock and processing means. In a stand-by condition, when the telephone is not being used as such but is ready to receive incoming calls, polling signals are processed during a predetermined portion of a repeated periodic cycle. After completing cycle processing, the system clock is de-activated. However, it is not necessary to calculate a de-activation period. Re-activation occurs at a predetermined position within the repeated periodic cycle in anticipation of receiving the next polling signals. <IMAGE> |
