Introduction
The Med-Fit Vagus Nerve Stimulator (tVNS) TENS & EMS Machine is designed to provide gentle electrical stimulation to the vagus nerve. This device aims to support the immune system, improve digestive function, reduce inflammation, and contribute to overall well-being by influencing sleep, mood, and energy levels.
The vagus nerve connects the brain to various major organs, playing a crucial role in regulating digestion, heart rate, sleep, and mood. Stimulation of this nerve helps to rebalance the autonomic nervous system, which can become imbalanced due to various factors, potentially leading to health vulnerabilities.

Operating Instructions
1. Electrode Placement for Vagus Nerve Stimulation (tVNS)
For optimal and comfortable vagus nerve stimulation, follow these steps:
- Apply Conductive Gel: Apply a small amount of the provided conductive gel to the skin of your ear where the ear clips will be placed. This ensures better conductivity and a more comfortable sensation.
- Attach Ear Clips: Carefully attach the Vagus double ear clips to the tragus (the small pointed cartilage in front of the ear canal) or cymba concha area of your ear, as indicated in the electrode placement guide. Ensure a firm but comfortable fit.

2. Using TENS and EMS Programs
The Med-Fit EM6100A unit includes preset TENS programs for pain relief and EMS programs for muscle strengthening, re-education, toning, and relaxation.
- Power On: Press the power button to turn on the device.
- Select Program: Use the mode selection buttons to choose between TENS (Transcutaneous Electrical Nerve Stimulation) or EMS (Electrical Muscle Stimulation) programs. Refer to the included Electrode Placement Guide for specific program recommendations and electrode pad placement for different body areas.
- Adjust Intensity: Gradually increase the intensity using the intensity control buttons. Start with a low setting and increase until you feel a comfortable, tingling sensation (for TENS) or a gentle muscle contraction (for EMS). Avoid increasing the intensity to an uncomfortable level.
- Session Duration: Follow the recommended session duration as per the program guide or your healthcare professional's advice.
- Power Off: After your session, gradually decrease the intensity to zero before turning off the device.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sensation or weak sensation | Low intensity setting, poor electrode contact, dead battery, faulty lead/electrode. | Increase intensity gradually. Ensure electrodes/ear clips are firmly attached and conductive gel is applied. Recharge the device. Check leads and electrodes for damage and replace if necessary. |
| Device does not turn on | Dead battery, device malfunction. | Charge the device fully. If it still doesn't turn on, contact customer support. |
| Skin irritation under electrodes | Electrodes applied to dirty/hairy skin, allergic reaction, prolonged use in one spot, dry electrodes. | Clean and dry skin before application. Change electrode placement regularly. Ensure electrodes are not expired or too dry. Discontinue use if irritation persists and consult a doctor. |
