Key Test Mode - Key

Press the RCL button to activate the key test mode, then press each button/knob to verify it works. If the button/knob works, a beep Will be heard after each button or knob is pressed. If the button/knob does not work, nothing Will be heard when the button/knob is pressed. Also, nothing will be heard when the AM/FM button or volume knob is pressed, but performance will be known once the desired functions are chosen. The AM/FM button will take the radio out of the key test mode and the volume knob will take the radio out of the on board diagnostic mode. To exit the key test mode, press the AM/FM button.
