Claim:
A two-way remote control unit, comprising: at least one first two-way remote controller being provided with a first code learning button and a first calling button; and at least one second two-way remote controller being provided with a second code learning button and a second calling button; wherein when the second code learning button is pressed, and then the first calling button is pushed to transmit the first calling code, the first calling code will be learned into the second two-way remote controller, so that the first two-way remote controller can remotely call the second two-way remote controller, locate a holder thereof, or an article connected thereto; and when the first code learning button is pressed, and then the second calling button is pushed to transmit the second calling code, the second calling code will be learned into the first two-way remote controller, so that the second two-way remote controller can remotely call the first two-way remote controller; whereby, the first and the second two-way remote controller can remotely call each other; and wherein one of the first and the second two-way remote controller that is being called can produce a sound and/or display a message showing the calling remote controller, so as to facilitate easy locating of the remote controller being called; whereby the first and the second two-way remote controller can be used to remotely call each other, so as to locate each other, the users thereof, or articles connected thereto; and whereby the two-way remote control unit enables not only one-to-one calling and locating between one first and one second two-way remote controller, but also multiple remote calling and locating among two or more first two-way remote controllers and two or more second two-way remote controllers.
