19
019: TG F Chk
Checks the Sound Source F (Autoscale) (SUB F).
Sequentially outputs the sine wave starting from the lower keys by switching the note
of the sound source. Checks if there is no noise or abnormal sound. When completing
the autoscaling, a note is output when a key is depressed (A certain note is output when
a respective note button is pressed).
20
020: TG XG Chk
Checks the Sound Source XG (Autoscale) (SUB XG).
Sequentially outputs the sine wave starting from the lower keys by using the sound
source of the piano. Checks if there is no noise or abnormal sound. When completing
the autoscaling, a note is output when a key is depressed (A certain note is output when
a respective note button is pressed).
21
021: Pitch Chk
Connect the frequency counter to the [PHONES] terminal.
Check that the 441.0 +/- 0.2 Hz sine wave is output.
22
022: Output R
Checks R channel output. (1 kHz)
AUX OUT L: -4 dBm
AUX OUT R: Should be lower than L channel by more than 50 dB
PHONES L: -7 dBm
PHONES R: Should be lower than L channel by more than 40 dB
23
023: Output L
Checks L channel output. (1 kHz)
AUX OUT L: Should be lower than R channel by more than 50 dB
AUX OUT L: -4 dBm
PHONES L: Should be lower than R channel by more than 40 dB
PHONES R: -7 dBm
24
024: EQ-Low
Checks EQ-LOW frequency
Checks if the output level of the sine wave 65.4 Hz(C1) can be -15 dBm when the
wave is output at PAN = Center.
(Measuring terminal: MA120-CN5 or A-JACK-CN240)
25
025: EQ-Mid
Checks EQ-MID frequency
Checks if the output level of the sine wave 523 Hz(C4) can be -16.5 dBm when the
wave is output at PAN = Center.
(Measuring terminal: MA120-CN5 or A-JACK-CN240)
26
026: EQ-High
Checks EQ-HIGH frequency
Checks if the output level of the sine wave 4186 Hz(C7) can be -16.5 dBm when the
wave is output at PAN = Center.
(Measuring terminal: MA120-CN5 or A-JACK-CN240)
27
027: D/A Noise
Checks D/A converter noise.
Play a note and check that there is no noise during the PIANO 1 release time.
(SUSTAIN ON, PAN = Center)
28
028: SW, LED Chk
Checks switch and LEDs on the panel.
Play the switch which is displayed on the LED. (The order is shown in the Table 1 for
page 29.) A pre-assigned note is output when he switches pressed. (With some switchs,
the corresponding LED will light up.)
29
029: All LED On
Check that all panel LEDs are lit.
Executes the test and check that all panel LEDs are lit.
30
030: Red LED On
Check that all panel Red LEDs are lit.
Executes the test and check that all panel Red LEDs are lit.
