Operations Description Event Description
The instrument plays 3 different tones.
At each action the instrument plays a tone and
when all actions are performed it plays three
tones.
1 tones for "-" button fault,
2 tones for "+" button fault,
3 tones for MIDI LOOP fault,
4 tones for DAMPER pedal fault,
5 tones for SOFT pedal fault,
6 tones for VOLUME potentiometer fault,
7 tones for SOSTENUTO pedal fault.
RPT114DL INITIAL CHECK
RPT114DL AUTOTEST PROCEDURE
The following procedures must be executed subsequently in the specified
order.
Before turning on the instrument, check the jumpers setting on CPU &
SOUND GENERATOR BOARD to be corresponding to the model accordingly
the following table:
Remove the secondary fuses F1, F2, F3, F4, located on POWER AMPLIFIER &
SUPPLY BOARD; turn on the instrument and verify the supply AC voltages:
Turn off the instrument and put the fuses back on its holders.
Turn on the instrument.
Check the supply DC voltages on CPU & SOUND GENERATOR BOARD:
To start the AUTOTEST mode, you must turn on the instrument and press 4
times the data "+" button within one second.
Note: During the autotest procedure the instrument does not respond at any
keyboard action.
The volume is set by its position at the moment of power on switching.
Active whole the following controls within 20 seconds:
"+" button, "-" button, SOFT. SOSTENUTO and DAMPER pedals, VOLUME
potentiometer.
If you have not activated some controls or their do not work properly, after
some seconds the instrument will play:
Note: the MIDI LOOP is checked if you connect a midi cable between MIDI
OUT and MIDI IN sockets.
Operations Description Event Description
The instrument plays 3 different tones.
1 tone for upper threshold value too high,
2 tones for lower threshold value too low,
3 tones for not enough threshold range.
RPT114DL KEYBOARD AUTOMATIC CALIBRATION
The most frequent reasons are the following, check these in the order specified below:
1) You have not activated one or more keys during the auto-calibration procedure.
Solution: repeat the auto-calibration procedure from beginning.
2) The optical sensors are dirty.
Solution: check these disassembling the keyboard, clean the optical sensors with a cotton flock slightly soaked
with denaturated alcool, reassemble the keyboard and finally repeat the auto-calibration procedure.
3) The optical sensor are out of the tolerance range.
Solution: disassemble the keyboard and replace on the contacts board the optical sensor that does not work
properly, reassemble the keyboard and check it repeating the auto-calibration procedure.
To start the AUTOMATIC CALIBRATION mode, you must turn on the
instrument and press 4 times the data "-" button within one second.
Note: During the calibration procedure the instrument does not respond at
any keyboard action.
The volume is set by its position at the moment of power on switching.
Press all the natural and sharp keys respecting the following precautions:
1) One or more keys at the same time is not important but each key
once at least.
2) Play the keys slowly with PPP (pianissimo) action as uniform as
possible for whole keyboard extension.
3) Release the keys slowly to avoid any oscillation or vibration.
4) Be sure that all keys are pressed at their end stroke, without apply
extra pressure.
Pressing "-" and wait since the instrument memorizes the new calibration.
If you do not hear a note your keyboard is successful calibrated. Pressing
again "-" and the instrument will restart in standard operation.
If the instrument play some notes the calibration is not done properly, the
keys not calibrated are notified in order from higher to lower tones, you may
hear for each note key:
