6. Electrode Pad Usage and Maintenance
The Comfytemp TENS Unit comes with premium medical PET TENS pads designed for all-day adhesion and painless removal.
6.1 Pad Types and Application
The package includes two types of pads:
- Butterfly-shaped pads (5.2 x 2.4 inches): Ideal for smaller muscle groups or targeted pain points.
- Line-shaped pads (3.5 x 2.8 inches): Suitable for larger areas or broader muscle groups.
The strong magnetic buckle ensures a stable connection between the host device and the electrode pad, preventing detachment even during movement.

The strong magnetic buckle ensures a stable connection between the host and electrode, preventing detachment even during physical activity.

The device includes two types of electrode pads: smaller butterfly-shaped pads for targeted pain points or small muscle groups, and larger wire-connected pads for broader areas or larger muscle groups.
6.2 Cleaning and Reusability
When the electrode pads lose adhesion, rinse the sticky part with clean water and gently scrape off any surface residue. Allow them to air-dry completely. This process can renew adhesion, enabling reuse for 60+ cycles. For optimal performance, ensure your skin is clean and free of lotions or oils before applying the pads. Shaving the area may also help prolong pad life.
