Abstract
A radio pager having means for automatically adjusting the rising time of a high-speed clock. The pager includes a plurality of circuit elements for adjusting the rising time of the high-speed clock, i.e., for compensating the degree of stability of a high-speed clock generating circuit. On the start of a low-speed clock, the high-speed clock generating circuit sequentially selects and connects the circuit elements to thereby count the resulting rising times of the high-speed clock. One of the circuit elements having resulted the shortest rising time is written to a storage. When the high-speed clock is needed, e.g., when a message should be displayed, the stored circuit element is connected to the high-speed clock generating circuit.
