1. LCD & LED testPress the pedal "1". The LCD starts displaying thetest pattern shown in Fig. 1. Verify that the segmentsare turned on.Press a key and verify that the 7-seg LED and thepedal LEDs are turned on in the order shown in Fig.2.
2. Switch testPress a key and the LCD will read "SW1".Press the keys in the order shown in Fig. 3 and verifythat pressed key is represented on the LCD.
The test stops upon detecting a defective key andwon't proceed to the next key. Take a correctiveaction and return to the step 1.When the test is successful , the test programproceeds to the step 3. DSP test.
3. DSP testThe test program automatically starts the test step 3 -1. after completion of the step 2.
3 - 1. InitializationWhen the unit is initialized, the program goes to thestep 3 - .2. Otherwise, it displays "ERROR 1" and
jumps to the step 4.3 - 2. Internal RAM testThe program writes the test data into and reads outfrom the internal RAM and then goes to the step 3 - 3.If error, it displays "ERROR 2" and jumps to the step4.3 - 3. External RAM test
The program writes the test data into and reads outfrom the external RAM and then goes to the step 4.If error, it displays "ERROR 3" and goes to the step 4.
4. Output frequency response testThe LCD displays "TEST 1". Sine waves of 20 Hz - 1kHz - 5 kHz - 15 kHz - 20 Hz from DSP are sent toOUTPUT sockets at0.8 sec.interval.Connect a noise meter to OUTPUT R. Set the meterto "FLAT" and check the readings against the tablebelow.Connect a noise meter to OUTPUT L (with the blankplug in R) and check the readings.The difference in readings between R and L must bewithin 1 dBm.Monitor OUTPUTs R and L and PHONES R and L inthat order on the oscilloscope and make sure they arelook like the waveforms shown in Fig. 4.
To go to the step 5, press VALUE + key.

5. Output stage muting testThe LCD displays "TEST 2". A 1 kHz sine wave fromDSP is sent to OUTPUT sockets at 0.5 sec. interval.In the similar way as in the step 4 above, connect thenoise meter or scope to OUTPUT R and then L (withthe blank plug in R)and check the readings. The difference in readingsbetween R and L must be within 1 dBm.Monitor OUTPUTs R and L and PHONES R and L inthat order on the oscilloscope and make sure they arelook likethe waveforms shown in Fig. 5.
To go to the step 6, press VALUE + key.To return back to the step 4, press VALUE - key.
6. OD and DS circuit testThe LCD displays "TEST 3". A 200 Hz square wavefrom DSP is sent to OUTPUTs at 0.8 sec. interval atfour different levels.Monitor the outputs by first connecting the scope toOUTPUT R and then L (with the blank plug in R) andmake sure thatthe waveforms look like the ones shown in Fig. 6.
To go to the step 7, press VALUE + key.To return back to the step 5, press VALUE - key.
7. OD and DS gain testThe LCD displays "TEST 4". A 200 Hz sine wave fromDSP is sent to OUTPUTs at an 0.8 sec. interval atfour different levels.Monitor the outputs by first connecting the scope toOUTPUT R and then L (with the blank plug in R) andmake sure that
the waveforms look like the ones shown in Fig. 7.
To go to the step 8, press VALUE + key.To return back to the step 6, press VALUE - key.
8. Input frequency response testThe LCD displays "TEST 5". Apply a square wave of200 Hz, 200 mV to INPUTs.Monitor the outputs by first connecting the scope toOUTPUT R and then L (with the blank plug in R) andmake sure thatthe waveform looks like the one shown in Fig. 8.
To go to the step 9, press VALUE + key.To return back to the step 7, press VALUE - key.
9. AUX circuit testThe LCD displays "TEST 6". Apply a square wave of200 Hz, 200 mV to AUX INP.The input signal is modified into three waveformswhich are sent to OUTPUTs at an 0.5 sec. interval.Monitor the outputs by first connecting the scope to
OUTPUT R and then L (with the blank plug in R) andmake sure thatthe waveforms look like the ones shown in Fig. 9.
To go to the step 10, press VALUE + key.To return back to the step 8, press VALUE - key.
10. Residual and shock noisesThe LCD displays "TEST 7". Short-circuit the inputs(e.g. insert a short circuit plug into INPUT and AUXIN).Set the noise meter to "JIS-A" or "IHF" and connect itfirst to OUTPUT R and then L (with the blank plug inR) and make sure that the readings are -88.0 dBm orbelow. Also verify that difference in noise levelbetween channels is 1 dBm or less.

In the similar way, connect a speaker via high gainamplifier to individual OUTPUTs. Apply shocks to theunit and make sureno audible noises are heard.
To go to the step 11, press VALUE + key.To return back to the step 9, press VALUE - key.
11. OD and DS circuit residual and shock noisesThe LCD displays "TEST 8". Short-circuit the inputs(e.g. insert a short circuit plug into INPUT and AUXIN).Set the noise meter to "JIS-A" or "IHF" and connect itfirst to OUTPUT R and then L (with the blank plug inR) and make surethat the readings are -84.0 dBm or below. Also verifythat difference in noise level between channels is 1dBm or less.
In the similar way, connect a speaker via a high gainamplifier to individual OUTPUTs. Apply shocks to theunit and make sureno audible noises are heard.
To go to the step 12, first connect the OUTPUT L tothe INPUT socket and then press VALUE + key (seenote in step 12).
To return back to the step 10, press VALUE - key.
12. NS and tuner testNote: "ERROR *" will appear if VALUE - key has beenpressed without connecting OUTPUT L to the INPUTsocket.
The LCD displays "TEST 9".12 - 1. NS bias testThe program checks the NS bias and, if correct, goesto the step 12.2. Otherwise, the program stops,displaying "ERROR 4".Adjust the bias and restart the test program from step1.
12 - 2. NS input testWhen the input is as designed, the program displaysthe tuner status. See Fig. 10. Press TUNER key.
If the input is incorrect, the program displays stopshere, displaying "ERROR 5" or "ERROR 6".Isolate the cause and restart the test program fromstep 1.To go to the step 13, press VALUE + key.To return back to the step 11, press VALUE - key.
