Battery operation check Entering the Test Mode 1.Set all the volume knobs to the left. 2.Connect a DC plug to the AC adaptor jack while pressing down the MANUAL/MEMORY button. (The MEMORY indicator blinks red.) 3.Press the

33、MANUAL/MEMORY button twice while it is blinking red (for 2 seconds). (The MEMORY indicator lights up green, enabling to enter the first test item.) Note: The test mode cannot be entered unless all the volume knobs are set to the left. Note: The test mode cannot be entered unless the button is operat

34、ed while the indicator is blinking red. Test Items 1. DSP and EEPROM check 1.After entering the test mode, DSP/EEPRO check is performed automatically. (The MANUAL/MEMORY indicator lights up green while checking.) 2.If no problem occurs, the “MANUAL/MEMORY” indicator lights up yellow after about 5 se

35、conds and the “ON/OFF” indicator lights up red. 3.If any problem is present, the relevant indicator blinks in the following manner: 4.Input a square wave (2000Hz, 400mVp-p) and check the output waveform (DSP through) with an oscilloscope. fig.wave0_45 2. WAH RANGE volume check 1.Input a square wave

36、(2000Hz, 400mVp-p). 2.Turn the volume knob from the lowest position to the center and to the highest position. The “MANUAL/MEMORY” indicator should light up, changing the color from yellow to green and to red, in this order. 3.Operate the volume knob to check that the oscillation of the output wavef

37、orm (DSP through) also changes from 0 to 400mVp-p or above. 4.After confirming that the indicator lights up red at the highest volume position, move on to DRIVE volume check. (In DRIVE volume minimum value detection, WAH RANGE volume maximum value detection is also performed. Leave the WAH RANGE vol

38、ume knob set to the highest position.) 3. DRIVE volume check 1.Test in the same manner as for WAH RANGE volume check, and check how the “MANUAL/MEMORY” indicator behaves as well as how the output waveform (DSP through) changes. 4. Pedal calibration 1.Press the MANUAL/MEMORY button to proceed to the

39、test items in the pedal calibration mode. (All indicators go off.) 2.Step down the pedal all the way back and hold it depressed. Note: Accurate calibration cannot be performed if the pedal is off the base or depressed beyond that point. fig.test4-1_30 3.Press the MANUAL/MEMOY button and check that t

40、he “MEMORY” indicator lights up red. Note: If the “MEMORY” indicator blinks red, go back to step 2 and check the pedal position, and then perform checking again. If the indicator blinks red each time checking is repeated, it indicates a faulty sensor circuit. Indicatorbehavior byerror type MANUAL/ME

Note: If the “MEMORY” indicator blinks green, it indicates a faulty sensor circuit. 6.Step down “the toe side” of the pedal hard and operate the switch

43、 on the toe side. Then check that the “MEMORY” indicator lights up yellow. fig.test4-3_30 7.Step down “the heel” of the pedal hard and operate the switch on the heel side. Then check that the “MEMORY” indicator lights up red. Note: Factory Reset is being performed while the indicator is blinking red

44、. Do not disconnect power from the unit. fig.test4-4_30 8.When completed, the “MEMORY” indicator lights up yellow, and the “ON/OFF” indicator lights up red. 5. BYPASS check 1.Set the TYPE volume knob to VOICE. (The “MEMORY” indictor lights up red.) 2.Check the output waveform (analog bypass) with an

45、 oscilloscope. fig.wave1_45 6. CODEC (DAC L ch) check 1.Set the TYPE volume knob to MO-WAH. (The “MEMORY” indictor lights up green.) 2.Check the output waveform (DSP internal oscillation, L ch) with an oscilloscope. fig.wave2_45 7. CODEC (DAC R ch) check 1.Set the TYPE volume knob to VO-WAH. (The “M

CODEC (DAC MIX) check 1.Set the TYPE volume knob to CBY-WAH. (The “MEMORY” indictor lights up green.) 2.Check the output waveform (DSP internal oscillation,

47、MIX) with an oscilloscope. fig.wave3_45 9. CODEC (ADC L ch) check 1.Input a sine wave (1kHz, -20dBm). 2.Set the TYPE volume knob to BASE MIX. (The “MEMORY” indictor lights up red.) 3.Check the output waveform (ADC L ch) with an oscilloscope. fig.wave4_45 10. CODEC (ADC R ch) check 1.Set the TYPE volume knob to ADVANCED.
