態にし設置場所が適切である旨表示してスタンバイ状態
に移行する。First, when the main unit is installed and connected to an AC power source and energized, the control circuit (6) that detects energization controls the receiving circuit (1) in step (S1) to start the channel search,
In step (S2), the indicator (10) blinks to indicate that the search is in progress. The channel search receives the designated channel based on the designation of the receiving channel by the control circuit (6), and checks the output of the carrier detection circuit (8) to determine whether the channel received in step (S3) is empty. , The control circuit which detected that it is in use by detecting the carrier
In step (6), the process proceeds to step (S1) to change the channel and receive the next channel. The channel search is repeated until an empty channel is found,
When an empty channel is detected in (S3), the indicator (10) is turned on, a message indicating that the installation location is appropriate is displayed, and the standby state is entered.
ノイズの発生源のない場所に設置する場合、通常親機の
通電でチャンネルサーチが開始されるとすぐに空チャン
ネルが見つかり指示器(10)が点灯状態となるため、好み
の場所に親機を設置することができる。When installing in a place where there is no noise source, normally when the channel search is started by energizing the base unit, an empty channel will be found and the indicator (10) will light up. Can be installed.

Carrier detection circuit (8) due to noise generated from device A
Becomes a state in which the carrier is detected, the empty channel cannot be detected in step (S3), and the channel search is repeated.
従って親機への通電時からいつまでも指示器(10)が点滅
した状態のときは、ノイズの影響を受けていると判断
し、ノイズの影響を受けず指示器(10)が点灯する位置へ
親機を設置するようにする。Therefore, if the indicator (10) is blinking forever from when the main unit is energized, it is determined that the indicator is affected by noise, and the indicator (10) is not affected by the noise and the indicator (10) is turned on. Install the machine.
