4. Electronic volume Test Mode (TEST 3)
When this test mode is obtained, the following display lights for one second.
In this mode, volume is -14 dB (STEP28), BASS/TREBLE is set to 0 (0 dB) and SURROUND mode to OFF, and start-up function
to CD, respectively. The button operations in the test mode are the same as those of ordinary operation except volume UP/
DOWN.

Set the current time and timer time according to the following procedure to reproduce the timer.
1.Set the current time to 1:00, the timer to ON time 1:05, the function to CD, and volume to STEP 12, respectively. One minute
is counted as one second, and the timer is reproduced. The fade-in (when playback is started) is executed at a rate of one step

After completion of fade-out, the power is turned off (after WAIT 1 sec), and the mode is shifted to the standby.
The display during operation is the same as that of ordinary timer operation.

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.

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.
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.
PLAY, BASS/TREBLE, FUNCTION, VOLUME UP/DOWN, MEMORY/SET, REW, FF, STOP, CD-OPEN/CLOSE

The OK/NG display of test result is as follows.
7. Button input diagnosis Test Mode (TEST 6)
When the test mode is obtained, the following is displayed.
a. POWER ON for function AUX
CD lid position is checked.
CLOSE position: Operation proceeds to the next process.
Position other than CLOSE: After the lid moves to CLOSE, operation proceeds to the next process.
Position other than CLOSE: After the lid moves to CLOSE, operation proceeds to the next process.

8. Electric CD lid Aging Test Mode (TEST 8) (Only for model with electric CD lid)
Outline
OPEN/CLOSE operations of electric CD lid are repeated. The number of repeated times and time period are monitored. If the
lid does not move to the regular position after the specified time, operation is stopped. When an error is detected by [CLID_PRO]
during CLOSE, operation is also stopped.
OPEN/CLOSE operations of electric CD lid are repeated. The number of repeated times and time period are monitored. If the
lid does not move to the regular position after the specified time, operation is stopped. When an error is detected by [CLID_PRO]
during CLOSE, operation is also stopped.
d. Display
OPEN>CLOSE is counted as 1. I to 59999 are counted; if the count is over
59999, display is returned to 0 to repeat counting.
59999, display is returned to 0 to repeat counting.

Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
