### How to Resolve Electrode Contact Errors During EEG Meditation Tracking
To instantly resolve electrode contact errors on your EEG meditation tracker, wipe the headband’s sensors and your forehead with a damp cloth to remove skin oils, then tighten the band for a snug, flush fit.
If you are still receiving a “Poor Signal” or “Contact Error” notification during your meditation session, walk through these quick troubleshooting steps:
#### 1. Prep Your Skin
* **Clear away hair:** Ensure no hair strands are trapped beneath the forehead or behind-the-ear sensors.
* **Remove oils and makeup:** Cleanse your forehead and temples with water. Avoid using moisturizers, face oils, or heavy creams before your session, as they block electrical signals.
* **Moisturize dry skin:** If your skin is extremely dry, dab a tiny drop of water or contact lens saline solution onto your skin where the sensors touch to improve conductivity.
#### 2. Clean the EEG Sensors
* **Wipe the electrodes:** Gently rub the metal or conductive fabric sensors with a cotton swab dipped in a tiny amount of rubbing alcohol to dissolve residue.
* **Dry completely:** Let the sensors air-dry for 30 seconds before putting the headband back on.
#### 3. Adjust the Fit and Placement
* **Tighten the band:** Ensure the headband is snug enough to press the sensors firmly against your skin, but not so tight that it causes discomfort.
* **Position correctly:** Make sure the primary forehead sensors are centered just above your eyebrows, and the reference sensors are securely hugging the skin behind your ears.
* **Relax your face:** Avoid frowning, squinting, or jaw-clenching during the initial calibration, as muscle tension mimics contact errors.
#### 4. Eliminate Environmental Interference
* **Unplug nearby electronics:** Move away from high-power devices, laptop chargers, or Wi-Fi routers, which can cause electromagnetic noise that the EEG sensors misinterpret as a connection failure.
