The electrodes are intended to be replaced regularly to prevent bacterial or other buildup, or degeneration of materials. Your electrodes should be replaced in either of the following cases:
- If there is significant discoloration, bad odors, or any noticeable separation of materials; or,
- After two weeks of daily use.
CAUTION: Inspect electrodes prior to use. Damaged or dirty electrodes will affect stimulation efficacy, and hence should be replaced regularly.
