Before you record a baseline or do a meditation training session, GoDeeper must first do a Signal check to make sure that the Muse is giving it a clear EEG signal. There are four ovals for each of the four sensors on the Muse. A new set of ovals appears each second to indicate the quality of the signal.
Here is what the colors mean and tips for how to get to all greens:
Black means that the app isn’t getting any signal from the Muse.
- If the ovals are all black, make sure the Muse is on and connected. If the Muse is on, then it is probably not connected.
- If only one or two are black ovals, try refitting the headband to make sure those electrodes are touching bare skin.
Orange means the signal is Noisy. That’s usually from not being still. Muscles make electrical noises that overpower the EEG signal. So it is important to be still during the signal check and while meditating. Sometimes Orange can be fixed by wetting the sensors.
Yellow means there is a Weak signal. This can be fixed by refitting the headband, making sure there is no hair or glasses between the electrode and your skin, and putting moisture on the electrode that is yellow. Saliva is a convenient source of moisture and a very good conductor of electricity between the electrode and your skin because it is salty. You can also wait until a thin bead of sweat forms under the electrode. That’s why pros turn on the Muse and put it on BEFORE opening the GoDeeper app. It gives more time for sweat to form and make a good electrical connection.
Green means there is a Good signal. We need to see ten seconds of good signal to proceed to meditating or recording a baseline.
