Claims

[Claims for Utility Model Registration] (1) A speed data standard that outputs a standard value of speed data at the start of scanning operation in a wireless communication device equipped with multiple operating frequencies and configured to scan the multiple operating frequencies. A value output means, a speed data variable means for arbitrarily setting the scan speed, a scan count data setting means for outputting scan count data based on the output from the speed data standard value output means or the speed data variable means, and a main routine. A scan speed variable device comprising: a scan counter decrement device that performs a decrement operation based on the output of the first round output device; and a PLL synthesizer step-up device that advances data of a PLL synthesizer using the output. (2) The variable scan speed device according to claim 1 of the utility model registration, characterized in that the scan speed is configured to return to the original speed when a certain limit is reached in order to prevent the scan speed from slowing down indefinitely.
