<p>PROBLEM TO BE SOLVED: To obtain an operation frequency and an access tone frequency of an available repeater, without having to perform dummy transmission. SOLUTION: In a step 1, scan preparation is set, and in a step 2, scan is started and receiving performed while a frequency is successively raised by prescribed width TS at a time, until a receiving signal is detected. In a step 3, when the receiving signal is detected, the scan is temporarily stopped and a tone scan function is operated to detect a matching access tone frequency. In a step 4, when the access tone frequency is matched, the matching access frequency Nn, a shift direction-Dup and a frequency Fn+Δf that is obtained by adding an offset frequencyΔf to the matching frequency Fn are all stored.</p> |
