Summary:PURPOSE: A method for adjusting a frequency of a digital wireless telephone communication terminal is provided to be capable of generating a frequency suitable for a TDMA communication way using a crystal and a variable capacity diode. CONSTITUTION: In a method for adjusting a frequency of a digital wireless telephone communication terminal, when a power of the digital wireless telephone communication terminal is on(ST1), predetermined frequency adjusting data is read from a frequency adjusting data storing part(ST2). The read data is transferred to a digital-to-analog converting part so that a predetermined voltage signal is generated corresponding to the read data(ST3). Whether a transfer frequency received through a feedback path is a frequency suitable for a TDMA way is judged(ST4). If so, a value of the frequency adjusting data is stored in the frequency adjusting data storing part(ST7). If not, the frequency adjusting data is reset(ST6), and then the steps(ST2-ST5) is repeated until the transfer frequency received through a feedback path becomes a frequency suitable for the TDMA way.
