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 ON/STAND-BY button, holding down the following two buttons in the ordinary standby mode (power off state). In this case only the main unit button is valid. Even when the ON/STAND-BY of remote control button is set to on, the test mode is not turned on.

[Ordinary test mode]

1.CD Test Mode (TEST 1)…………………… BASS/TREBLE + FF/FWD

2.Tuner Test Mode (TEST 2)………………… BASS/TREBLE + REW/REV

3.Electronic volume Test Mode (TEST 3)…… BASS/TREBLE + REC

4.Timer Test Mode (TEST 4)………………… MEMORY/SET + REC

5.LCD Test Mode (TEST 5)……………………MEMORY/SET + REW/REV

[Self-diagnosis Test Mode]

1.Button input diagnosis test mode (TEST6).… MEMORY/SET + PLAY

2.CD Test Mode (TEST 1)

In the CD test mode the operation of each step is enabled even when the LID-SW is off. However, if focus cannot be set in step 3 or any error processing is started, it is impossible to proceed to the next step. When the error processing is started, operations other than termination of test mode by pressing the ON/STAND-BY button or return to the step 1 by pressing the STOP button are inhibited.

1. Step 1 Mode

When the CD test mode is turned on, the following indication lights, the processing (until turning-off of CD STB terminal of CD initialization operation flow) is executed, and the next button input is waited.

After lighting for one second

If the following operation buttons are pressed in this state, the operation is performed as follows.

"ON/STAND-BY" ......	The test mode is turned off, the power is turned off, and the ordinary stand-by mode is set.
"FF/FWD" .................	After the pickup returns once to the innermost periphery, it slides toward the outer periphery while this
	button is held down.
"REW/REV" ..............	After the pickup returns once to the innermost periphery, it slides toward the inner periphery while this
	button is pressed. However, if PU-IN is on, input is invalid.
"PLAY" .....................	Shift to step 2
"STOP" .....................	Invalid
"REC PAUSE"..........	Shift to step 5

XL-55H/65H

*In case of initialization the pickup is moved toward the inner periphery. Any buttons other than ON/STAND-BY button are not accepted until the shift of pickup to the inner periphery is completed at this time. If PU-IN SW ON cannot be detected within 10 seconds, the slide motor is stopped, and the following error indication appears. Press the ON/STAND-BY button to end the test mode, or press the STOP button to return to step 1. Any other operations are inhibited.

2. Step 2 Mode

When the "PLAY" button is pressed in this mode, the laser lighting command LDON (8400) is sent, and the laser is turned on. Other operations are not performed.

If the following buttons are pressed in this state, the operation is performed as follows.

"ON/STAND-BY" .....	The test mode is turned off, the power is turned off, and the ordinary stand-by mode is set.
"FF/FWD" ................	The pickup slides toward the outer periphery while this button is held down.
"REW/REV" .............	The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
	is invalid.
"PLAY" .....................	Shift to step 3
"STOP" ....................	Return to step 1
"REC PAUSE" .........	Shift to step 5

3.Step 3 Mode

The laser is kept lighting. The processing (until turning-on of CLV servo of CD initialization operation flow) is executed, and the next button input is waited. (The focus servo is turned on, and focus search is performed.)

The focus search is repeated until the focus is set.

When the following operation buttons are pressed in this state, the operation is executed as follows.

"ON/STAND-BY" .....	The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD" ................	The pickup slides toward the outer periphery while this button is held down.
"REW/REV" .............	The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
	is invalid.
"PLAY" .....................	If the focus has been set, shift to step 4 is executed. If the focus has not been set, acceptance is inhibited.
"STOP" ....................	Return to step 1
"REC PAUSE" .........	Shift to step 5

*If the focus is disturbed after it has been set, the process returns to step 1.

4.Step 4 Mode (Only focus "OK" can make this item showing)

The CLV servo ON command (8600) sending operation is performed, and the next button input is waited. (The disc is rotated to perform CLV locking.)

The time display indicates always "0:00".

When the following buttons are pressed in this state, the operation is executed as follows.

"ON/STAND-BY" .....	The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD" ................	The pickup slides toward the outer periphery while this button is held down.
"REW/REV" .............	The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
	is invalid.
"PLAY" .....................	Shift to step 5
"STOP" ....................	Return to step 1
"REC PAUSE" .........	Shift to step 5

*If the focus is disturbed, the process returns to step 1.

5.Step 5 Mode

The CD initialization operation flow is executed to the end, the mute is set to off, and playback is started. Even when the playback reaches the outermost periphery of disc, the operation does not stop. The LCD display indicates the playback past time as in case of ordinary CD playback.

When the following operation buttons are pressed in this sate, the operation is executed as follows.

"ON/STAND-BY" ......	The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD" .................	The pickup slides toward the outer periphery while this button is held down.
"REW/REV" ..............	The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
	is invalid.
"PLAY" .....................	Invalid
"STOP" .....................	Return to step 1

*If the focus is disturbed, the process returns to step 1.

Other cautions

•TOC IL is not executed in the test mode.

•As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted.

3.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 ON/STAND-BY button while the BASS/TREBLE and REW/REV 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 obtained.(Memory/Set+Function Key Span Charged) (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 BASS/TREBLE+ REW/REV. -> POWER OFF -> 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 + STOP.

When this mode is set, BASS/TREBLE is set to 0 (0 dB) and start-up function is set to CD when volume is -14 dB (STEP 23). 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 is switched when button operation is performed.

5.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 1:05, set the function to Aux, and set volume STEP 12. 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 1 sec. After completion of fade-in the fade-out is executed at a rate of one step for 1 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 standby mode.

The indication during operation is the same as that of ordinary timer operation.

6. 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

7. 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 "ON/STAND-BY" 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 "ON/STAND-BY" button is pressed next time, and the standby mode is set.

1. In case of "MEMORY/SET" + "PLAY"+ "ON/STAND-BY"

Since SURROUND and RDS are not provided, the following 9 buttons are detected as all buttons.

PLAY, ON/STAND-BY, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP.

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