Fix it in this order
- Record the full message
Capture code 4210, the exact wording, mower model, positioning status, battery level, and time. - Check whether the mower is online
Refresh the mower in the app. Resolve an offline state before diagnosing RTK. - Refresh the app session
Close and reopen the app, then allow time for service and positioning status to update. - Test in open sky
Move away from buildings, dense trees, metal roofs, and retaining walls. - Check Network RTK settings
Confirm the feature is enabled for the correct mower, account, model, and region. - Restart once
Use the documented shutdown process, wait briefly, and restart without repeated rapid cycles. - Check official notices and updates
Install only firmware offered in the Navimow app and check support for service notices.
What usually causes this?
Loss of internet access, a temporary correction-service interruption, weak satellite visibility, an account or feature-status problem, or outdated firmware can trigger this warning.
How to verify the fix
The positioning status should recover, code 4210 should remain cleared, and a short supervised run should hold an accurate position.
Do not skip this check: a cleared warning is not proof of a repair. Confirm the mower completes the affected action under supervision before restoring unattended schedules.
Frequently asked questions
Should I delete the map first?
No. Fix power, connectivity, positioning, and hardware placement first. Remapping can hide the original cause.
Should I install an update?
Install only an official update offered for your exact model and keep power and connectivity stable.
When should I stop?
Stop for damaged wiring, unusual heat, battery swelling, burning odor, water inside electrical parts, or repeated hardware faults.
When to contact support
Contact Navimow if 4210 returns while the mower is online in an open area. Send the exact model, serial number, screenshots, firmware and app versions, time of failure, and whether another positioning mode works.
