This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode, it is checked
whether the "ON/STAND-BY" button was pressed after all the buttons shown below were pressed. If the result is OK, OK is
displayed. If any one of keys was not pressed, an error is displayed. In both cases of OK termination or error termination, the
mode is shifted to the standby mode if the "ON/STAND-BY" button is pressed subsequently.

All models using this type of microcomputer are not always provided with the same buttons. Since the buttons used are different
depending on models, types of buttons to be used are determined by whether RDS, SURROUND, and an electric lid are
available at the initial setting by MODEL port.
