Wave ROM check 1
To check the Wave ROM checksum connected to the CPU bus (Simplified check).
For the OK test result, the C4 sine wave sounds (for 1 second).
For the NG test result, the C2 sine wave sounds (continuously until any key is pressed).

TG check
The sine wave sounds from the low range in the key range (C2 – G4) capable of sounding
(Auto Scaling)
while the sound production channel of the sound source is changed one after another.
(The sound stops after sounding of all 32 channels.)
Check that no abnormal sound or noise is generated.
When a key is pressed after Auto Scaling, the sine wave sounds. (Single sound, priority on
first-come)
Press the lowest key to end this test.

Pitch check
Connect the frequency counter to the [PHONES] jack for measurement.
Check that the 441.0 Hz ± 0.2 Hz sine wave sounds at the level of specification (DAC input
full bit -12 dB). (PAN = Center)
Volume decline value
Connect the level meter (with JIS-C Filter) to the [PHONES] jack for measurement.
Set the master volume to the minimum position and check that the output level is within the
range specified below.
PHONES L: -90 dBu or less, PHONES R: -90 dBu or less
When the test item is ended with the lowest key, the sound stops.

Output level R check
Check that the 1 kHz sine wave sounds at the level specified below (DAC input full bit -12dB).
(PAN = R)
Connect the level meter (with JIS-C Filter) to the [PHONES] and [AUX OUT] jacks
(P-105B/
P-105WH only)
for measurement.
PHONES L: -55.0 dBu or less, PHONES R: -8.5 dBu ± 2 dB

Fail safe check
To check that the abnormality detection circuitry for fail safe of the digital volume operates
properly.
Press the [TEMPO UP] button (P-105B/P-105WH) / B6 key (P-35B)
and check that the outputs (speakers, headphones and AUX OUT) are muted.
Press the [TEMPO DOWN] button (P-105B/P-105WH) / B7 key (P-35B)
and check that the outputs (speakers, headphones and AUX OUT) are not muted.
