A method and devices that apply radio frequency remote control device to find objects, the major part of the present invention is a radio frequency remote control device which is mounted at a fixed position. The radio frequency remote control device has an internal timing device, for special purpose users such that the device can make audible and/or visible warning signals to remind the user of the time of medication. By applying the working principle of radio frequency transmitting and receiving function, when the setting time has arrived or the user presses a button, the radio frequency remote control will emit a coded signal according to the receiving instruction. This signal is the received by a receiver. After decoding, if the signal is correct, the warning device in the receiver will emit audible and/or visible signals to allow for the user to locate the object. Thus achieve the convenience of modern life. The radio frequency remote control is also capable of duplicating the codes of other radio frequency transmitter control device.
