While speeds can be changed via service port and laptop with judit software, all EFG machines come with 3 different speed programs (P1,P2 & P3). Changing between them depends on your machine's configuration, there may be seperate button, or on machines with cancode just press 1-2-3 for representive programs.

I think on 1series the (arrow up-down)button is behind steering. Also note that 1series have the most limited configuration options even in service program.

Hello,
This must be done via a diagnostic laptop.
