Maintenance

Troubleshooting
- No Sensation: Ensure pads are firmly attached to the skin and cables are securely connected to both the pads and the device. Gradually increase intensity. Check battery level.
- Weak Sensation: Increase intensity gradually. Ensure pads are not dry; moisten if necessary. Replace old pads if stickiness is lost.
