TEST MODE

The test mode applied to this microcomputer has three modes, namely ordinary test mode to be used for adjustment or measurement, aging test mode to be used for aging test, and self-diagnosis test mode for self-inspection in case of final product inspection.

1. Turning on the test mode

To turn on the specific test mode, press the POWER button, holding down the following two buttons in the ordinary stand-by mode (power off state). In this case only the main unit button is valid. Even when the POWER of remote control button is set to on, the test mode is not turned on.

[Ordinary test mode]

1. Tuner Test Mode (TEST 2)............................. Volume/JOG Dial Selector + Volume Select

2. Electronic volume Test Mode (TEST 3) ......... REW/REV + FF/FWD

3. Timer Test Mode (TEST 4) .............................FUNCTION + Volume Select

4. LCD Test Mode (TEST 5) ...............................FUNCTION + FF/FWD

[Self-diagnosis Test Mode]

1. Button input diagnosis test mode (TEST6)..... REW/REV + Volume Select

2. Tuner Test Mode (TEST 2)

1. Outline of tuner (radio) test mode

The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH without

frequency setting by adjusting personnel when the tuner section is adjusted in the production line.

2. Details of tuner test mode

When the power is turned on by using the "POWER" button while the "Volume/JOG Dial Selector" and "Volume Select"

buttons are held down in POWER OFF state, the frequency for adjustment and measurement of destination specified by the AREA terminal is preset and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation (destination selected by SPAN switching operation) set when the test mode is set. (As for frequencies to be preset and stored

for each destination, refer to item 3.) The tuner test mode is started from preset No.1. The operations of test mode are identical with the ordinary operations of TUNER function. However, FUNCTION switching

is invalid. Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are

written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected

in case of initial setting so as to ensure memory initialization.

When the tuner test mode is turned on, the following indication lights for one second.

• The TUNER TEST2 mode is set as a result of Volume Select + POWER. -> IF AC is set to OFF in the TEST2 mode, the initial

state is restored.

When POWER is set to OFF, the memory of TEST2 mode is protected. When the power is turned on again, the ordinary operation is enabled while the data is stored in the memory (besides TUNER).

If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.

• To clear the whole memory, insert the AC cord, holding down MEMORY + PLAY.

3. Electronic volume Test Mode (TEST 3)

When the test mode is set, the following indication lights for one second.

When this mode is set, BASS/TREBLE is set to 0 (0 dB) and SURROUND mode is set to off, and start-up function is set to CD when volume is -14 dB (STEP 17). The button operations in the test mode are the same as those of ordinary operation excepting sound volume UP/DOWN.

(1) The indication is the same as that of ordinary operation excepting test mode setting. (2) The sound volume control with the sound volume UP/DOWN button is only the following 3 steps unlike the ordinary state.

Volume- ∞ (STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)

(3) BASS/TREBLE and SURROUND are switched when button operation is performed.

4. Timer test Mode (TEST 4)

When the test mode is set, the following indication lights for one second.

The current time and timer time are set in the following procedure to perform the timer playback.

1. Set the current time to 1:00, set the timer to ON time 1:02, set the function to Tape, and set volume STEP 8. One minute is counted as one second, and the timer playback operation is performed. The fade-in (when playback is started) is executed at a rate of one step for 0.5 sec. After completion of fade-in the fade-out is executed at a rate of one step for 0.5 sec (WAIT 1 sec inserted). After completion of fade-out the power is turned off (after WAIT 1 sec), and the mode is changed to the stand-by mode. The indication during operation is the same as that of ordinary timer operation.

5. LCD Test Mode (TEST 5)

When the LCD test mode is set, all the LCD segments are lighted. After that the indication is changed as follows according to the "PLAY" button input.

Lighting of all segments Lighting of odd segments Lighting of even segments

6. Key input diagnosis Test Mode (TEST 6)

When the test mode is set, the following indication appears.

This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode checking as to whether the "POWER" button was pressed after all the buttons shown below were pressed is performed. If the result is OK, OK is indicated. Even any one of keys was not pressed, an error is indicated. In case of OK termination or error termination exit from this mode occurs when the "POWER" button is pressed next time, and the stand-by mode is set.

1. In case of "FF/FWD" + "REC PAUSE"

Since SURROUND and RDS are not provided, the following 11 buttons are detected as all buttons. PLAY, JOG MODE, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP, CLOCK/TIMER/ SLEEP.

The OK/NG indication of test result is as follows.
