Checking The Version On Silent Pianos And Grantouch Models - Yamaha Disklavier MX100A Product Handbook

7. Checking the Version on Silent Pianos and GranTouch models

Since Silent Pianos and GranTouch models do not have controllers, you need to use the keyboard to engage ver-
sion-check mode. The piano then identifies the sensor and tone-generator versions by playing out notes as
described below. This operation is common for all models that lack controllers.
Enter version-check mode: 2A# + 5C#+7D#+ [POWER]
