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 turn

34、ed completely down. Furthermore, the unit will not enter test mode if, due to faulty volume controls or other causes, the minimum value is not detected for all volume controls. *The unit enters Test mode even without an expression pedal (EV-5) connected to the EXP jack. *If CHECK does not light, if

35、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 Check” in “Tests.” *For instructions on skipping tests in order to perform only a particular test item, refer to “Instructions for Skipping Tests.

36、” Exiting Test Mode The pedal may be pressed to exit Test mode. *“17. Battery Check” and “18. Noise Check” are not Test mode items, but are performed in Normal mode. Instructions for Skipping Tests Follow the instructions in “Entering Test Mode” and switch to Test mode. When the pedal is released, t

40、, CPU Check Refer to “Entering Test Mode” and switch to Test mode. 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 INPUT, in

41、put a rectangular wave (200 Hz, 100 mVp-p), and check the waveform output with the oscilloscope from both OUTPUT A(MONO) and OUTPUT B. Confirm that the waveform output is the same 200 Hz, 100 mVp-p waveform shown in the figure (DSP THRU). fig.test-DSPthru.eps_40 50mV/DIV, 1mS/DIV If CHECK lights up,
