Check out the video for instructions on how to access the hidden diagnostic/service menu on many Husqvarna Automower models. This one is the 450x. If you don't own one already, mine has been nothing but problems - I'd recommend shopping other brands personally.
To access the menu go to "Menu" and then hold the 7 and 9 keys simultaneously. Throw this video a like if it helped you!
