Abstract
The invention provides a radio communication system allowing a user to readily set a delay time. The controller determines whether the test button was depressed and then determines how long the test button has been kept depressed. The depressed time is set as a delay time and stored in a memory. After a lapse of the set delay time, the controller starts a communication with a master unit, determines whether the installation site of the slave unit 10 is appropriate and notifies the determination. If a normal communication is recognized from the determination result, the user decides to install the slave unit to the tested installation site and terminates the test.
