How to Fix Other Issues on the Poseidon M80(No Sound, The screen shows "not support"etc.)?🔥🔥🔥

1. Try switching channels or adjusting the volume to see if the issue is resolved

2. If switching channels or adjusting volume does not work, we recommend powering off and restarting the device.

3. If restarting does not resolve the issue, perform a factory reset (please press and hold the "MUTE" reset button on the remote for 5 seconds, or use the app to restore factory settings).

If none of the above works, upgrade to the latest firmware version. Please provide your current firmware version and SN when contacting support service, so we can push the software update.
