1) Automatic mode:  When the [START] button at the bottom of the Fig. 2 screen is pressed, selected checking items will be executed 
sequentially from the upper left downward. All judgment columns become blank when checking is started.
    If the [STOP on NG] is selected, checking is stopped temporarily when judgment is NG.
    Checking stops temporarily when the [PAUSE] is pressed and stops when the [STOP] is pressed during the 
temporalstop. Checking is re-started when the [CONTINUE] is pressed.
2) Individual mode:  If the button with OK/NG indication is pressed in Fig. 2, an individual checking screen as shown in Fig. 3 will be 
displayed. Press the [START] in each screen to execute the checking.
3) For the checking items and checking contents, refer to “List of Check Items” below.
4) For the “items to which no checking is to be executed” in each checking screen, their characters are dimmed (grayed out)
5) The fi le storing the checking results should be named as “Storage fi le name.csv”. (Only general check results will be saved.)
6) It is possible to save the communication results (right side of Fig. 3) as a fi le. (Up to 30 KB)
 The fi le should be named as “Storage fi le name.txt”

When there is Ok Data,
When checking visually, this box is displayed.
OK button and Enter key are linked.
Used to start checking. 
During the checking, this button 
becomes [CONTINUE] button and 
restarts checking when pressed 
during temporal stop.Used to stop checking 
temporarily. Works as 
[STOP] during temporal 
stop, and pressing it will 
force to end checking.Closes this screen to 
return to Fig. 2 screen.When the check is marked here, OK and data being transmitted are displayed 
for debugging this PC program (No check mark when program is started.)
Auto Next function
· When checking is started in automatic mode, the Auto Next function is turned on and checking proceeds automatically.
· When checking is started in individual mode, the Auto Next function is turned off. Checking is started using the [START] button.
· To recheck the NG item in automatic mode, press the [PAUSE] button, turn off the Auto Next function and press the [START] button. OK: is also displayed. Indicated when the total judgment of 
all individual items is completed.
Judgment result of each item
NO appears when there is 
no communication response
Operation instructions are displayed in
 red and processing status in black.Communication contents are displayed while checking all items.

Contents: Checks each interface of the MY SLOT and power supply voltage supplied to the SLOT.
Example of executing screen
1)	 Checking	SLOT 	power	voltage
  Use of the MY SLOT CHECK Ver.2 check jig makes it possible to check the SLOT power voltage automatically.
  For this check, the judgment voltage of the MY SLOT CHECK Ver.2 check jig must be adjusted as specified before the SLOT test.
  It  is  also  possible  to  take  measurement  at  each  voltage  terminal  of  the  MY  SLOT  CHECK  Ver.2  check  jig  using  a  tester  with  the 
power	check	box	set	to	Manual.
LS9-32:	COM	test	is	only	for	the	SLOT1.

1-21. Fader Travel Time Measurement Test
	 Press 	any 	3 	switches 	simultaneously 	in 	the 	Encoder 	Input	
Test 	mode 	to 	enter 	the 	Fader 	Travel 	Time 	Measurement	
Test	mode.
	 During	 checking,	"FADER	TIME	MEASURE	 Test"	will	be	
shown	on	the	LCD	screen	and	on	PC.
	 After 	all 	the 	faders 	reciprocate 	several 	times, 	8 	faders 	are	
moved	 upward	 and	downward	 at	a	time	 and	checked	 if	the	
travel time is within a specified range.
	 The 	judgment 	result 	is 	shown 	by 	lighting 	of 	the 	SEL/ON	
LEDs	on	each	fader.
	 If	 the	upward	 travel	time	is	NG,	 SEL-LED	 will	light	 and	if	
the	downward	travel	time	is	NG,	ON-LED	will	light.
	 Measurement 	time 	of 	each 	fader 	will 	be 	displayed 	on

	 Check	the	following: 	 ·	 Make 	sure 	that 	all 	the 	SEL/ON 	LEDs 	on 	each 	fader 	are	
turned	off.
	 ·	 Make 	sure 	that 	the 	judgment 	shown 	by 	the 	PC 	application	
and	LCD	are	OK.
Press	any	one	switch	to	restart	the	test.

	 Channels	 1	through	 16	of	the	 LS9-32	 using	the	FD2	 circuit	
board 	are 	judged 	by 	moving 	faders 	with 	all 	patterns 	of	
different	inspection	bit	value	and	measuring	the	travel	time.
	 All	 the	channels	 of	the	 LS9-16	 using	the	FD	 circuit	 board,	
channels 	17 	through 	32 	and 	STEREO 	of 	the 	LS9-32 	are	
judged 	by 	reading 	DA 	output 	for 	only 	2 	faders 	directly 	to
