CS6X A. HOW TO ENTER THE TEST PROGRAM C. TEST SELECTION WHEN AN ERROR HAS BEEN DETECTED While pressing the [VOICE], [PERFORM] and [STORE] switches, turn on the [POWER ON/OFF] switch. The following message will then appear. When the test result has been judged as “NG” in each of the following tests, choose whether to execute the same test or to proceed to the next test. In this state, pressing the [EXIT] switch will cancel the test mode and restore the normal state.
CS6X DISPLAY OF RESULTS OK If the wrong switch is pressed, “NG” will appear and no sine wave will be output. If the correct switch is pressed after that, testing will proceed to the next switch. If the test results for all switches are satisfactory, “OK” will appear. The switches are checked in the following order. [VOICE]>[PERFORM]>[STORE]>[UTILITY]>[CARD]> [SEQ]>[EDIT]>[JOB]>[PLAY/STP]>[SHIFT]>[EF.BYPS]> [MASTER]>[EXIT].[ENTER]>[DEC/NO]>[INC/YES]> [PRE1]>[PRE2]>[INT]>[EXT]>[PLG1]>[PLG2]>[Q.
CS6X T7. KEYBOARD DISPLAY OF RESULTS OK This test is used to check that the keyboard functions properly by scaling 88 keys from A1 to C7. NG (The above shows the C1 check.) x x x x: velocity value of the key being pressed When the key on the LCD display works at a velocity of 0X10 to 0X6F, it is considered normal and that keys note is output. The test will then proceed to the next key test. If a wrong key is played, “NG” will appear and that note’s sound will not be output.
CS6X x x x: current knob value y y y: next target value ZZZ: name of the Knob being checked Checking order: [ATK][DCY][SUS][REL][POR][PCH] [SCN][PAN][ARP][TMP] DISPLAY OF RESULTS OK NG (No change in the message on the display) TEST END The test ends after the results have been displayed. When the test result is “NG”, refer to “C. TEST SELECTION WHEN AN ERROR HAS BEEN DETECTED”.
CS6X T14. BREATH CONTROLLER x x x: current value of the breath controller Operate the breath controller in the following order: Not blowing (122-127) - Blowing (0-5) - Not blowing (122-127) - Not blowing - Blowing - Not blowing, remove the jack when “EXTRACT PLUG!” appears on the LCD. At this time, check that the plug is not plugged in, the numbers change sequentially and that “OK” appears on the LCD. (The test is “OK” when the value is 34 or less.
CS6X DISPLAY OF RESULTS OK NG (No change in the message on the display) TEST END When the test results of all switches are satisfactory, “OK” will appear on the LCD and the testing will end. When the test result is “NG”, refer to “C. TEST SELECTION WHEN AN ERROR HAS BEEN DETECTED”. Set the master volume to Max and check that the following signals are output from OUTPUT-L, INDIV1 and 2, and PHONES (L). OUTPUT-L: 1 kHz ±1.5 Hz, sine wave, +6.
CS6X T21. A-D LEVEL, JACK Set the A/D GAIN volume to the maximum level. Input a 1 kHz sine wave of the following level through the A/D input port according to the instructions on the LCD. MIC: -40 dBm ±0 dBm LINE: -6 dBm ±0 dBm When a plug is connected to the jack, both “EXTRACT PLUG” appears and the A/D level appear. When a plug is not connected and the level is 2 or lower, “INSERT PLUG” appears and when a plug is inserted, the A/D level will be indicated.
CS6X NO-BOARD: board is not loaded. CONTROL: CONTROL line failure TEST END When the [EXIT] switch is pressed, the sound output will stop and the next test number will be set. T25. DISPLAY OF RESULTS When the factory settings are restored OK When the factory settings are not restored NG mLAN TEST END The test ends after the result is displayed. Connect the mLAN board to the mLAN slot and execute testing.
CS6X T28. EXIT (3) Turn on the power while pressing [EXIT] and [ENTER], and the system program will be loaded from SMART MEDIA and the operating power will be restored. (4) Turn on the power while pressing [DEC] and [INC], and the wave data will be loaded from SMART MEDIA, and the operating power will be restored. When testing is executed, the following message will appear on the LCD. When [YES] is pressed, testing will end.
