C-520 TEST MODE

How to enter the TEST MODE, Confirmation of the click noise when power on

Pushing [PERFORMANCE] and [SPLIT] then turn power on. Confirm that big click noise is not heard when power on. After "Self Test Select Mode" is displayed in the LCD, select one mode from following 3modes.

Push [PIANO 1]; Internal Inspection + External Inspection (Connect MIDI IN and MIDI OUT, loop connection) Push [PIANO 2]; External Inspection (Inspection starts from LCD inspection) Push [E.PIANO 1] Internal Inspection + External Inspection (without MIDILOOP and USB inspection)

Operation in the TEST MODE (without LED/SW inspection)

Push [+/YES] step up within the item Push [-/NO] step down within the item Push [EXIT] proceed to the next item

Internal Inspection about PCB and internal system

Connect a cable or a jack to the headphone jack surely.

ITEM STEP

1 1 NANDFLASH - Partition.0

2 NANDFLASH - Partition.1 2 1 MIDILOOP (When not connected MIDI IN and OUT, the judgment is NG.) 3 1 USB 4 1 Headphone Insert (When no cable or no jack is connected, the judgment is NG.) 5 1 TGL Resister

2 TGL DRAM 6 1 PCMROM BANK.0

2 PCMROM BANK.1

3 PCMROM BANK.2

4 PCMROM BANK.3

When some error is detected, the meaning of the error is displayed in the LCD. When no error is detected, C-520 proceeds to the next external inspection.

When you skip the error and proceed to next, push [+/YES] .

External Inspection, about the operation system of panel.

1 LCD Inspection

Confirm the unevenness of the contrast by displaying of all dots and not displaying of all dots.

1 display: [LCD]

2 displaying of all dots

3 not displaying all dots

2 LED/SW Inspection

Confirmation of the operation and the display of the switches and LED Confirm that only one LED in the inspection lights, and the brightness is even, no strange feeling, push a switch then, the inspection proceeds to the next one by one.

3 Pedal Inspection

Step on the left, center, and right pedal in the order, when value of the A/D is normal, the inspection proceeds to next automatically. When all the 3 pedals are normal, C-520 proceeds to next inspection.

1 left pedal

2 center pedal

3 right pedal

4 Measurement of the maximum level

The sine wave of 1000Hz is output from the channel which is measured. When R is not connected, the mixed signal (L+R) is output from L. When measurering, connect cables to L and R.

When measuring of L, 660Hz signal is output from R. When measuring of R, 330Hz is output from L.

Push [METRONOME], then the inspection proceeds to the next step. After Headphone2R, the inspection proceeds to the measurement of the noise. When you do not measure, push {METRONOME] six times and proceed.

5 Headphone 2 L

1.5～5.5 [dBu]

33 ohm load is needed.

6 Headphone 2 R

1.5～5.5 [dBu]

33 ohm load is needed.

5 Measurement of noise level

When measuring, connect cables to both L and R.

Push [METRONOME], then inspection proceeds to the next step.

After Headphone "R, next is Measurement of the line input.

When you do not measure, push {METRONOME] 6times and proceed the inspection.

6 Measurement of the LINE INPUTS

When measuring, connect cables to both L and R. Input -10[dBu] signal only to the input which you measure.

Push [METRONOME] to proceed to the next step.

After Lineout R, next is the confirmation of speaker sound. When you do not measure, push [METRONOME] twice and proceed.

7 Confirmation of the speaker sound

Input the decided signal only to the input which you measure.

After confirmation of the sound from the speaker, push {METRONOME} and proceed to the next item.

1 Left speaker low Input the sine wave of -10[dB] 128[Hz] to the Linein L

2 Right speaker low Input the sine wave of -10[dB] 128[Hz] to the Linein R

3 Left speaker high Input the sine wave of -10[dB] 12500[Hz] to the Linein L

4 Right speaker high Input the sine wave of -10[dB] 12500[Hz] to the Linein R

8 Inspection of the keyboard

Play each key at the middle strength from the C8 (right end) to the A0 ( left end). In the LCD, the key which you should play next is displayed.

After the keyboard inspection ended normally, C-520 restarts in the normal mode.

9 Confirmation of the working of the product

After the restart of the normal mode, confirm the demo song playing and working of the product

for example, sound volume and etc.
