Entering Test Mode Turn all volume controls down completely (to minimum). Set MODE to DRIVE. Hold down the pedal and connect the DC plug to adapter ja

29、ck. When CHECK lights up, release the pedal. The CHECK light goes off for approximately two seconds, then lights again, indicating that the unit has entered test mode. The unit will not switch to test mode unless all volume controls are turned completely down. Furthermore, the unit will not enter te

30、st mode if, due to faulty volume controls or other cause, the minimum value is not detected for all volume controls. If CHECK does not light, if may be due to a faulty LED. Switch the pedal on and off in Normal mode to confirm that CHECK lights and goes off. If CHECK flashes, refer to “1. DSP, CPU C

31、heck” in “3. Tests.” For instructions on skipping tests in order to perform only a particular test item, refer to “5. Instructions for Performing Only Desired Tests” following the detailed descriptions of the test items. 3. Tests 1.DSP, CPU Check Refer to “2. Entering Test Mode” and switch to Test m

32、ode. A check of the DSP and CPU is performed automatically while the CHECK light is off. If no problem is detected, CHECK lights up and the unit enters Test mode; CHECK flashes if an error has occurred. Connect the oscillator to GUITAR IN or BASS IN and input a rectangular wave (200 Hz, 100 mVp-p) a

33、nd check the waveform output with the oscilloscope from both OUTPUT (MONO) and DIRECT OUT. Confirm that the waveform output is the same 200 Hz, 100 mVp-p waveform shown in the figure (DSP THRU). fig.test-DSPthru_50 50mV/DIV, 1mS/DIV If CHECK lights up, the process automatically advances to the next

34、step. If CHECK flashes, it may be due to a fault surrounding the DSP or CPU, faulty soldering, or other such problems. Disconnect the DC plug from the adapter jack and turn off the power. 2.DIRECT LEVEL Volume Check Rotate the knob in the clockwise direction from minimum to center, then to maximum;

35、CHECK should change from lit to off to lit. When the maximum is detected, CHECK lights up, and then the process advances to the OCT1 LEVEL Volume Check. 3.OCT1 LEVEL Volume Check Rotate the knob in the clockwise direction from minimum to center, then to maximum; CHECK should change from lit to off t

36、o lit. When the maximum is detected, CHECK lights up, and then the process advances to the CONTROL (RANGE, OCT2, DRIVE) Volume Check. The maximum values for the OCT1 LEVEL Volume Check and DIRECT LEVEL VOLUME are detected simultaneously. The OCT1 LEVEL Volume Check is not run unless the DIRECT LEVEL

37、 Volume maximum is detected. 4.CONTROL (RANGE, OCT2, DRIVE) Volume Check Rotate the knob in the clockwise direction from minimum to center, then to maximum; CHECK should change from lit to off to lit. When the maximum is detected, CHECK lights up, and then the process advances to the AF/AD Check. 10

38、 Sep.2003 The maximum values for the CONTROL Volume Check and the OCT1 LEVEL Volume are detected simultaneously. The CONTROL Volume Check is not run unless the OCT1 LEVEL Volume maximum is detected. 5.AF/AD Check Confirm that the MODE control is set to DRIVE. Use the oscillator to input a sine wave

Confirm that each waveform output is FLAT and between -28.5 dBm and -25.5 dBm. 6.DAC, JACK Switch Check Confirm that the MODE control is set to OCT2. CHECK goes off. Use the oscillator to input a sine wave at 200 Hz, -25 dBm (FLAT) to GUITA

41、R IN. Connect plugs to both the OUTPUT (MONO) and DIRECT OUT jacks, and check the waveform output from both jacks with the oscilloscope. Confirm that the waveform output from DIRECT OUT is a 200 Hz rectangular wave, the waveform output from OUTPUT (MONO) is a 200 Hz sine wave, and that the waveform

42、is the same as that shown in the figure. fig.test-DA200HzD_50 50mV/DIV, 1mS/DIV Disconnect the plug connected to the DIRECT OUT jack.
