The best way to calibrate the Autopilot is via the web interface. * To calibrate the compass, go to: [Compass Calibration](/autopilot/operate/web-interface-apps/compass-calibration.md) * To calibrate the rudder, go to: [Rudder Calibration](/autopilot/operate/web-interface-apps/rudder-calibration.md) *** ### How to Update the Firmware? The firmware of the Pcnautic Autopilot is continuously being improved. When a new release becomes available, you will be notified via email.\ You can update the firmware through the [web interface](/autopilot/operate/web-interface-apps.md) on the [Maintenance](/autopilot/operate/web-interface-apps/maintenance.md) page. If the regular update method does not work for any reason, an alternative [Emergency](/autopilot/operate/web-interface-apps/maintenance/emergency.md) page is available to perform the firmware update. *** ### **Firmware update not working** Updating via the Android app is not possible, update via the web interface: First, try updating the firmware again following the [regular instructions in the manual](/autopilot/operate/web-interface-apps/maintenance.md#update-firmware). If it still doesn’t work, use the special [Emergency](/autopilot/operate/web-interface-apps/maintenance/emergency.md) page to perform the update. *** ### The ControlHead / Motor Controller does not power on If the ControlHead or Motor Controller does not power on, it is recommended to check the fuse inside the Motor Controller and replace it if necessary. *** ### Error Message "No motor controller" on ControlHead There is no communication between the ControlHead and the Motor Controller. Please check the wiring between the ControlHead and the Motor Controller. *** ### **WiFi access point not visible** Click [here](/autopilot/operate/controlhead-bedienkast.md#wifi) for instructions to reset the WiFi settings to factory defaults using the Controlhead. *** ### **Forgot WiFi password** Click [here](/autopilot/operate/controlhead-bedienkast.md#wifi) for instructions to reset the WiFi settings to factory defaults using the Controlhead. *** ### **What is the IP address of my Autopilot?** 1. Go to **WiFi** on the Controlhead. 2. Press **M**. 3. The IP address is shown at the bottom (default: **192.168.14.1**). *** ### **Connected to the Autopilot but no IP address in the IP lease list?** If you’ve set a manual IP address, it will not appear in the list of DHCP leases. The list only shows automatically assigned (DHCP) IP addresses. *** ### **What is the “Servo error log” on the Statistics page?** This log displays error messages from the motor controller, such as: * Excessive current * Servo out of range * Other hardware-related errors *** ### **Acoustic alarm from the Controlhead – what does it mean?** When the option **"Servo min/max rudder fault beep active"** is enabled, a warning signal sounds if the servo moves outside its allowed range. *** ### **No connection to the web interface via browser or Android app** If you are unable to connect to the web interface (via browser or Android app) while being connected to the Autopilot via WiFi, try disabling mobile data. *** ### **Connected to Autopilot, but no internet access** When you connect your phone to the Autopilot via WiFi (in Master (AP) mode), most phones will lose internet access over 4G or 5G. A solution for this can be found under [Connecting to both the Autopilot and the internet](/autopilot/operate/web-interface-apps/wifi-network-config.md#connecting-to-both-the-autopilot-and-the-internet). *** ### **Other issues with the Pcnautic Autopilot** Can’t solve the issue using this FAQ? Please send an email to [**info@pcnautic.com**](mailto:info@pcnautic.com) with a clear description of the problem. Also include log files, which you can download via the [**Maintenance**](/autopilot/operate/web-interface-apps/maintenance.md#download-logs) page. --- # Agent Instructions This documentation is published with GitBook.
