S80 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.
S80 T3. WAVE ROM This test compares each wave ROM data. DISPLAY OF RESULTS OK NG If any IC is NG, the test result will be NG. TEST END The test ends after the result is displayed. 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].
S80 T7. KEYBOARD x x x: current knob value y y y: next target value This test is used to check that the keyboard functions properly by scaling 88 keys from A1 to C7. DISPLAY OF RESULTS OK (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.
S80 Operate the FOOT VOLUME, FOOT CONTROLLER, SUSTAIN SWITCH and FOOT SWITCH according to the instruction on the LCD as described below. Check that the numbers change and that “OK” appears as the result. T12. CONTROLLER x x x: current knob value Move the PITCH BENDER, MODULATION WHEEL, RIBBON and AFTER TOUCH controllers according to the instructions on the LCD as described below. Check that the numbers change sequentially and that “OK” appears as the result.
S80 DISPLAY OF RESULTS OK NG (No change in the message on the display) TEST END The test ends after the result is displayed. When the test result is “NG”, refer to “C. TEST SELECTION WHEN AN ERROR HAS BEEN DETECTED”. Connect a MIDI cable to MID IN and OUT, and then begin testing. If the IN and OUT check results are “OK”, connect the MIDI monitor with THRU and check that the test pattern (AA•FF•00•55) is output. DISPLAY OF THE RESULTS OK NG (When different data has been received) T15.
S80 T18. TO HOST DISPLAY OF RESULTS TEST END AUTO: Connect pin No.3 to pin No.5, and connect pin No.6 to No.8, and then execute testing. Operate the HOST SELECT switch according to the instruction on the LCD and check that “OK” appears when [MIDI] is reached at the end. When the HOST SELECT switch is set to the MIDI position, the “SET HOST Sw [MAC]” message will appear. Next set the HOST SELECT switch of the main unit to MAC to begin testing.
S80 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. “OK” will appear when the AD level is within the following range. MIC: 75 or greater and 85 or less LINE: 75 or greater and 85 or less When MIC is OK, the LINE check will be executed automatically.
S80 T25. When the factory settings are not restored NG mLAN Connect the mLAN board to the mLAN slot and execute testing. After checking the connection of the mLAN board, the signal transmission and reception of the MIDI line, the RESET request signal, and the operation of OUT + SWP30 of the MEL line by the external clock, check that “OK” appears. Also, confirm that a 900 Hz sine wave output is obtained as the final signal at OUTPUT L and R. TEST END The test ends after the result is displayed.
S80 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.

S80 MIDI DATA FORMAT Many MIDI messages listed in the MIDI Data Format section are expressed in hexadecimal or binary numbers. Hexadecimal numbers may include the letter “H” as a suffix. The letter “n” indicates a certain whole number. The chart below lists the corresponding decimal number for each hexadecimal/binary number.
