Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the robot before cleaning the speaker area.
Basic checks:
- In the Tesvor app, check the volume settings and increase if necessary.
- Clean the speaker grill with a soft brush or compressed air to remove dust.
If audio remains distorted or silent: The internal speaker may be damaged or the audio circuit on the main board may have failed. Replacing the speaker is relatively simple if accessible; if that does not help, main board replacement is required.
