CONSTITUTION: An antenna of a wireless repeater is moved in various directions(S30). At this time, RF signals are inputted to a down link RF(Radio Frequency) receiver, and amplified to a certain level then outputted. An RF output level detector detects the RF signals, and temporarily stores detected down link input values, or RSSIs(Received Signal Strength Indicators), in an internal buffer of a CPU at predetermined time intervals(S31). The maximum value of the RSSIs is stored in a register(S32). In a state that a direction check button is pressed, the antenna is moved in various directions(S34). Whether an RSSI approaches the maximum value is checked(S35). If the stored value is coincident with the RSSI, an LED(Light Emitting Diode) blinks(S37-1,S37-2), and if not coincident, the LED is lighted(S36) and the step S35 is returned. If an end key is inputted after the wireless repeater is installed(S38), an interrupt is generated in the CPU(S39) and a normal mode is operated(S40).
