Chapter 7
Text Messages and Troubleshooting
7.1 Messaging
The RoboMower is equipped with a sophisticated monitoring system that will notify you in the form of a text
message in the LCD panel when common operational faults occur. In addition, it will also communicate in text form
several messages that are meant as a prompt to the user to perform a certain function or action. If the LCD screen
is blank, pressing the ‘GO’ button one time will wake the mower up and the last fault or message displayed prior to
stopping will now be displayed. If a specific problem re-occurs, it is recommended to identify the fault code prior to
calling for service. The code will be displayed in the ‘last stop cause’ under the ‘information’ menu.
While it is impossible to list every circumstance that will result in a message display, the most common reasons for a
particular message are provided in the following chart. Following this chart, in Section 7.2, you will also find
additional operational and fault issues that may not display a particular text message in the LCD panel. For issues
that cannot be resolved through the use of these charts please contact your service provider.
