Troubleshooting
If you encounter any issues with your metronome, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Metronome does not power on. | Battery is depleted. | Connect the metronome to a power source using the USB cable and allow it to charge. Ensure the ON/OFF switch is in the 'ON' position. |
| No sound or low sound output. | Volume is too low or muted. Headphones are connected. | Adjust the volume using the 'VOL SOUND' button and central dial. If headphones are connected, sound will output through them. Disconnect headphones if you wish to use the internal speaker. |
| Tempo/Rhythm settings are not changing. | Incorrect button pressed or dial not turned. | Ensure you are using the correct 'RHY' or 'BEAT' buttons and turning the central dial for tempo adjustment. |
| OTG function not working. | Smartphone/MP3 player not OTG compatible or cable issue. | Verify your external device supports OTG. Ensure the OTG cable is correctly connected and functional. |
| Battery meter shows low charge even when charged (as reported by some users). | Potential display anomaly or confusion with external battery compartment. | The metronome uses a built-in Lithium-Ion battery. While there might be a compartment for AAA batteries, it is not functional for power. Rely on the charging indicator for the internal battery. If the device functions normally despite the display, it may be a minor display issue. If it fails to hold a charge, contact support. |
