Thanks for the information.
Locate the bottom right fuse in the main panel under the dash. Key off, pull it out.
Turn the ignition switch to the accessory position where all the lights light up on the dash. Do not crank it up.
Use the black square button to toggle through the dash. Short press to toggle, long press to select. From there, you can change some parameters as well as clear some trouble codes.
To save, just turn the switch off, count to 30 Mississippi, replace the fuse, and fire her up.
Be careful not to tamper in there too much.
This is the same for the 1700 premium series, 1700M series, and 4600 series.
This stuff is in the operator's manual, but hard to understand in English.
