E3, DKC-800, and DKC-850 usb sofware update

A firmware update is needed to continue using the internet features of the E3(DKC-800)/DKC-850 especially when it has not had a firmware update installed recently.

For this Yamaha Disklavier System, use the control unit to update the software and restore the use of the internet again with your grand piano or upright piano.

It is not necessary to have a serviceman from an Authorized Yamaha Dealer in the United States to schedule an appointment to update a Disklavier. With a Tech-Savvy mindset, it is simple to update your piano and I will show you how (ios devices not needed).

The first time I updated the software for this system it was intimidating, however, these instructions I created with Noah Jolly make it simpler.

As you may know, the Mark III upgrades to the DKC-850; the Mark IV upgrade to a DKC900 does not need this particular update.
