Disklavier 4 : How to calibrate keys/pedals without remote PRC-100 ?

How to calibrate keys and pedals of a disklavier IV without PRC-100 remote ?

Any solution (except PRC100!) appreciated...

Thank you !

As far as I know, the only solution would be to find an engineer with a PRC100 who could run through the calibration procedure.

I was under the impression that there were some keys you could hold down on the keyboard itself while turning the piano on that would cause it to go through the calibration procedure as well.  I'm not sure why I had that idea though...

I'll see if I can turn anything up.

That procedure applies to GranTouch, Silent and Avant Grand pianos.

From the MarkIV service manual (I sure hope it's okay to post this!):

1) The purpose of the function
In order to execute calibration procedure even if the PRC-100 control unit is not together with Disklavier.
2) Possible procedures
a) Key sensor / hammer sensor calibration
b) Key board calibration (Full) (15 minutes)
c) Pedal calibration ( incl.Pedal half point auto adjustment )
d) Pedal half point manual adjustment -- When it is necessary.
3) Restrictions
a) No display is available.
The results of each calibration will be informed by the type of harmony --> 7)
b) No stop button is available. --> 8)
c) Key board full calibration takes 15 minutes.
4) Operational procedure
a) Turn to the Stand-by mode. ( Refer to 5-11.)
b) The light of standby button on the media center at the bottom of keybed dims.
c) Select a key switch pattern --> 5)
d) Hold the keys and turn the standby button of the Media Center on.
e) Release the keys after 6-7 seconds after the clicking sound comes.
f) The selected calibration will be executed in 10 seconds.
g) Harmony tells you the result.
h) Back to all active mode.
5) Key switching combinations
Depress and hold both C#(77key) + D#(79key) keys and press the following additionally .
F# (82key) Key sensor / hammer sensor calibration
G# (84key) Pedal calibration
A# (86key) Key board calibration
C (88key) Pedal half point manual adjustment
You can combine all the calibration procedures except half point adjustment.
(ex.) C# + D# + F# + G# + A# -->¨ All calibration executes in sequence.
6) Pedal half point manual adjustment -- 1.5 sec. damping adj.
Adjust pedal mute timing to approx. 1.5 seconds after coming harmony by using 1second interval
sound.
Press [shift pedal] to save data
Press [3key] for lower damping
Press [1key] for quicker damping
7) Harmony display
C major, C, E, G --> Complete calibration
C minor, C, D#, G --> Error occurred
8) Forced termination
Press Stand-by button on the Media Center and back to the Stand-by mode before data writing.
NOTE ! : Calibrated data will be all deleted when you push the button during writing data.
