4. Setup and Charging
- Charge the Device: Fully charge the unit before first use. Connect the USB cable to the device's USB port and to a wall charger, power bank, or laptop USB port. The battery level indicator on the screen will show charging status.
- Prepare Electrode Pads: Clean the desired application area on your skin with alcohol to ensure it is free from dirt, oil, or lotion. This helps maintain pad adhesion and effectiveness.
- Connect Pads to Wires: Snap the electrode pads onto the electric wire cables. Ensure a secure connection.
- Connect Wires to Device: Plug the electric wire cables into the A and/or B output connectors at the bottom of the device. The unit supports dual channels, allowing two sets of pads to be used simultaneously with independent intensity control.
- Apply Pads: Carefully peel the protective film from the pads and firmly attach them to the desired body area. Ensure full contact with the skin.
