1. A remote unit operable in an idle mode to alternately wake-up and to enter a sleep mode, said remote unit comprising:

  • a processing unit for controlling said remote unit;

    a clock signal generation system for generating system timing signals input to said processing unit, said clock signal generation system including;

    a first clock pulse generating unit for generating first clock pulses;

    a first counter for counting said first clock pulses and outputting one of said system timing signals when a counted number of said first clock pulses exceeds a first predetermined threshold;

    a second clock pulse generating unit for generating second clock pulses;

    a second counter for counting said second clock pulses and outputting one of said system timing signals when a counted number of said second clock pulses exceeds a second predetermined threshold; and

    a mechanism for receiving said system timing signals from said first and second counters and outputting system timing signals to said processing unit from said first counter when said processing unit is to wake-up and outputting system timing signals from said second counter when said processing unit is in sleep mode.
