3.1 -MAIN MENU
>RUN ALL TESTS
The Main Menu item "Run All Tests" does precisely that. If one was to answer YES (3 in the 1000 EX, EGP, K1000 or Mark III) to this menu item, all tests would be run as a result. If no MIDI connector is connected between MIDI In and MIDI Out, or in the case of 1000 Keyboard products (K1000, EGP and Mark III) there is no shorting connector installed in J12, ERRORS WILL RESULT! If the unit responds with the display
“PASSES >00001 ERRORS >00000,"
the test has passed.
>RUN SELF TESTS
The Main Menu item "Run Self Tests" will run only the tests that do not require operator supervision, or cables to be plugged in. This makes a perfect "Burn-In" test. If the unit responds with the display "PASSES>00001 ERRORS>00000," the test has passed.
>RUN LCD TEST
The Main Menu item "Run LCD Test" does just that, providing a visual display of the alphabet, and the numbers 0-9, plus a few interesting extras. If the display shows these numbers and letters properly, the test has passed .
>RUN BUTTON TEST
The Main Menu item "Run Button Test" tests the front panel push buttons. When this test is run, the buttons can be tested by pushing them and reading the LCD display to see that the button identity displayed on the LCD matches the label on the front panel silk screen. This test is cancelled by pushing one of the buttons twice. Please see the test for the specific product to see exactly which button this is. If all of the buttons pushed display an
identity on the display that matches the front panel silk screen, the unit has passed.
Kurzweil1000 Series Service Manual, Chapter 3 3- 2
>RUN MIDI TEST
The Main Menu item "Run MIDI Test" tests the MIDI Input and Output by placing a cable between the two, and sending data in loop back fashion. Please make sure the cable from MIDI In to MIDI Out is in place before running this test. If the unit responds with
the display "PASSES>00001 ERRORS>00000,” the test has passed.
>RUN SINE WAVE T
The Main Menu item "Run Sine Wave Test" sends a specific set of sine waves out of the Left and Right Audio Outputs in order to test them. The tests performed are Frequency Response, Distortion, and Signal to Noise. These tests require a dB meter and Distortion Analyzer of moderately high quality.
>RUN BATTERY TST
The Main Menu item "Run Battery Test" is used to test the non-volatile, battery-backed RAM. This RAM is where user r--- programs are stored. This test is run by first selecting II > R U N ALL TESTS," "RUN SELF TESTS," from the Main Menu, or ">RAM TEST" from the Test Select Menu. This will place a test pattern in RAM. Next, turn the unit off and wait 1 minute. Then turn the unit on, holding down the two buttons used to enter the diagnostics. Entering the diagnostics is described in Chapter 2.
PLEASE MAKE SURE THA T THE UNIT DOES NOT COME UP INTO
PLAY MODE!
If the unit comes up into it's normal mode, you must re-run the previous test(s) to place the proper pattern back in the RAM.
Select ">RUN BATTERY TEST" from the Main Menu, and push Go (Yes). When the LCD display responds with "NUMBER OF PASSES > 001,” push Go (Yes) .If the unit responds with the display "PASSES>00001 ERRORs>00000,” the test has passed.
Kurzweil1000 Series Service Manual, Chapter 3 3- 3
> TEST SEL MENU
The Main Menu item "Test Select Menu" lets the user change menus to the Test Select Menu. This menu allows the user to run individual tests, not batteries of tests. If an error occurs while running "ALL TESTS," one can run the individual test that failed by selecting it in the Test Select Menu.
>CONFIGURE MENU
The Main Menu item "Configure Menu" lets the user configure the diagnostics to debug problems with an oscilloscope, or modify the error displays given.
>ERROR STATS
The Main Menu item "Error Stats" lets you read the statistics from one or more passes of the diagnostics. If a section of hardware has failed any time during the test process, it will be displayed as a failure when this menu selection is chosen. Also displayed are the number of passes, and the number of errors. If a test is aborted by pushing the cancel button, the statistics for the last pass of the diagnostics are lost.
>EXIT SUPERVISOR
The Main Menu item "Exit Supervisor" quits the diagnostics and returns the unit to the normal, or play mode.

the Tektronix AA501 Distortion Analyzer / AC Voltmeter. If the sine wave show amplitude and distortion levels within the r criterion listed in these sections, the test has passed.
Kurzweil1000 Series Service Manual, Chapter 3 3- 7
>SEVEN SAMP TEST
The Test Select Menu item "Seven Sample Test" uses both Arnold chips to produce the maximum number of sine waves possible, all seven samples long. The test then checks each Arnold's internal FIFO to make sure that it contains samples that are legitimate samples from the seven sample sine wave. THIS TEST IS NOT CURRENTLY GUARANTEED TO PASS IN ALL UNITS! This test is not run when ">RUN ALL TESTS," or "RUN SELF TESTS" are selected.
>LCD SCOPE TEST
The Test Select Menu item "LCD Scope Test" is different than the previous ">LCD VISUAL TEST ," or ">RUN LCD TEST ." This test sends bursts of data at much higher speeds than normal to the LCD. Normal LCD data transfers occur at too slow a rate to be
seen well with an oscilloscope. This test allows the user to do oscilloscope debugging of the LCD.
>MAIN MENU
The Test Select Menu item "Main Menu" allows the user to go to the Main Menu to run batteries of tests.
>CONFIGURE MENU
The Test Select Menu item "Configure Menu" lets the user configure the diagnostics to debug problems with an oscilloscope, or modify the error displays given.

3.3 -CONFIGURATION MENU
The menu items in the Configuration Menu respond a bit differently when selected than the other two menus. The Configuration Menu expects the user to answer yes or no to questions about the units configuration. If you wish to leave configuration in its default or
current state, one pushes neither the Yes (3 in the 1000 EX, PX Plus, EGP, K1000 and Mark III), or No (4 in the 1000 EX, PX Plus, EGP, K1000 and Mark III) buttons. When a mode has been selected by pushing Yes (3), a "V" will appear in the lower right hand corner of the display. When a mode has been de-selected by pushing No (4), an "N" will appear in the lower right hand corner of the display. You may exit the Configuration Menu by selecting one of the other two menus.
>SIG ANALYSIS
The Configuration Menu item "Signature Analysis" selects a mode which DOES NOT REPORT ANY ERROR MESSAGES, EVEN IF A TEST SHOULD FAIL! This mode is used for collecting signatures to provide signature analysis debugging. This mode can also be used to get better scope traces on failed tests. If the purpose of a test is to get a good scope trace, and not to visually see the error messages, one can select Signature Analysis Mode. As described above, this mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or N o
(4) is pushed.
>LOOP ON ERROR
The Configuration Menu item "Loop On Error" causes all tests that fail to repeat as long as they fail. If there is a RAM error every time the RAM Test is run, the RAM Test will run over and over again, forever. This mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or No (4) is pushed.
Kurzweil1000 Series Service Manual, Chapter 3 3- 9
.
>DISP ERR TEXT
The Configuration Menu item "Display Error Text" chooses whether or not to display a textual error message every time an error occurs. An example of this is: "ER45>MIDI LOOP BACK ERROR U67." You can either select this mode to be displayed or not displayed when an error occurs, by pushing Yes (3), or No (4).
>DISP ERR DATA
The Configuration Menu item "Display Error Data" chooses whether or not to display a the expected and observed data every time an error occurs. An example of this is: "ER45 ADDR>58001 EX>OOOO 08>0001." You can either select this mode to be displayed or not displayed when an error occurs, by pushing Yes (3) , or No (4).
>DISP BAD BITS
The Configuration Menu item "Display Bad Bits" chooses whether or not to display a the bits that failed data every time an error occurs. An example of this is:
"15 -(ER45 BITS)- 0"
"***************B"
The bits that are bad are flagged with a "8." This display works for both Address and Data bits. Bit 15 is on the left and bit O is on the right. You can either select this mode to be displayed or not displayed when an error occurs, by pushing Yes (3), or No (4).
>SCOPE LOOP
The Configuration Menu item "Scope Loop" allows the user to see tests run more clearly on an oscilloscope, at the expense of not being able to read the error message very clearly. This selection causes the error message to be displayed for only a few microseconds, and then goes back to run the test again (if Loop On Error, or multiple passes were selected). This mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or No (4) is pushed.
Kurzweil1000 Series Service Manual, Chapter 3 3-10
>ERR MESS FAST
The Configuration Menu item "Error Message (Display) Fast" selects the error message to be displayed for about two seconds. This mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or No (4) is
pushed.
>ERR MESS SLOW
The Configuration Menu item "Error Message (Display) Slow" selects the error message to be displayed for about five seconds. This mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or No (4) is
pushed.
>ERR MESS HOLD
The Configuration Menu item "Error Message (Display) Hold" selects the error message to be displayed until the user pushes the cancel button. This mode is selected by pushing Yes (3), de-selected by pushing No (4), and it remains unchanged if neither Yes (3) or No (4) is pushed.
>MAIN MENU
The Configuration Menu Item "Main Menu" allows the user to go to the Main Menu to run batteries of tests.
> TEST SEL MENU
The Configuration Menu item "Test Select Menu" lets the user change menus to the Test Select Menu. This menu allows the user to run individual tests, not batteries of tests. If an error occurs while running " ALL TESTS," one can run the individual test that failed by selecting it in the Test Select Menu.
