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.
The order of buttons to be pressed is not determined.
Accordingly, it is checked whether all buttons have been
pressed.
1. PU-IN buttons: REW/PRESET DOWN + CD STOP
Since this model is provided with SURROUND (HAVE
OR NOT), RDS (HAVE OR NOT), and electric CD lid, the
following 10 buttons are detected as all buttons.
