7. Button input diagnosis Test Mode (TEST 6)
When the test mode is obtained, the following is displayed.
(STAND-BY AND DEMO OFF STATUS)
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 termi-
nation 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
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),
and electric CD lid, the following 10 buttons are detected as all but-
tons.
PLAY, X-BASS/DEMO, FUNCTION, VOLUME UP/DOWN, MEM-
ORY/SET, REW, FF, STOP, DISK TRAY OPEN/CLOSE
The OK/ERROR display of test result is as follows.
