Please ensure that BrainLink has sufficient electric quantity and has been turned on, and that the red/blue Bluetooth indicators are flickering alternatively. Then, enable the Bluetooth function in the Bluetooth setting of the terminal device, and then wait several seconds. "BrainLink" should appear in the Bluetooth list, and auto-pairing will start next. Some old devices might request you to enter the Bluetooth pairing code. Please enter "0000". If successful pairing, the device in the list has been connected, and only the blue Bluetooth indicator of BrainLink is flickering.

Please refer to the "BrainLink Quick Start Guide" inside the packing box, or download the app "BrainLink" from App Store, where the animation video will teach you how to conduct the Bluetooth pairing.

1. Please restart the terminal device and clean the caches in the Bluetooth list. Excessive Bluetooth or previously connected BrainLink will result that the device cannot search the new Bluetooth again. Restart the device and conduct the pairing again.

2. Please check the Bluetooth indicators on the BrainLink. If only the blue indicator is flickering, it indicates that BrainLink has connected with another device. Please turn off the Bluetooth of another device to disconnect, and then conduct the Bluetooth pairing with the new device.

3. If you use the mobile phone or tablet PC with Android system, please refer to the manual and ensure that your device is provided with the Bluetooth function and supports the connection with the third-party Bluetooth. Some Android devices use the closed Bluetooth protocol, and it will result that BrainLink cannot set up the Bluetooth connection with such devices.

4. If you use the Apple’s iOS device (iPhone or iPad), please ensure that the device system has been updated to the latest version. See the following link for the compatibility: http://o.macrotellect.com/usehelp.html

Actually, to wear the BrainLink correctly, just ensure that the two metal sensors contact the forehead and earlobe. Please refer to the "BrainLink Quick Start Guide" inside the packing box, or download the app "BrainLink" from App Store, where the animation video will teach you how to wear the BrainLink correctly. After wearing the BrainLink correctly, you should be able to hear two prompt tones.

You can also visit the following link: http://o.macrotellect.com/usehelp.html to watch the BrainLink video tutorial.

1. Please read and familiarize the descriptions of connecting signals in the "Signal Description" in the app "BrainLink" (search the keyword "BrainLink" on the App Store, and you can download for free), and operate according to the descriptions and suggestions.

2. Please click the connecting signal icon on the top right corner to open the advanced detection function. Observe the raw brainwave pattern, and operate according to the app descriptions.

3. Please try to close the apps running in the background, particularly the apps compatible with BrainLink or using Bluetooth. These apps are possibly occupying the Bluetooth channel.

4. Please restart the device and connect the Bluetooth again.

Because the cerebro-electricity signal is extremely weak, the brainwave detection stability is easily interfered by the outside world. Here are some frequently-seen circumstances affecting the stability:

1. Shake violently or blink or talk frequently, resulting in myo-electricity interference.

2. Hair, earrings or other objects contact with the metal sensor, or cover up the contact with the metal sensor.

3. Excessive sweat or cosmetics blocks the metal sensor. Try to wipe the sweat or other impurities on the forehead and sensor.

4. The metal sensor does not fully contact with the skin. It is suggested to adjust the ear clip to ensure that the two sensors inside the ear clip are close to the earlobe, and additionally, observe whether the metal sensor on the forehead is close to the skin contact surface on the forehead. Adjust the elastic band properly to allow the forehead to be close to the sensor.

5. There are strong electromagnetic wave interferences or lots of electronic devices (particularly wireless devices) in the surrounding environment, e.g. mobile phone communication, TV screen, air-conditioning and camera, etc.

6. The environment is too noisy, and high-decibel acoustic wave will also produce interference.

The above circumstances can be troubleshot in the advanced detection functions (refer to the app "BrainLink" -> signal descriptions -> advanced detection functions). To achieve the optimal experience effect, please exclude the above circumstances to ensure the cerebro-electricity detection stability. Alternatively, you can try to wear the BrainLink again and wait several seconds patient until the prompt tones and the green icon of correct wearing appear.

Similar to the principle of electrocardiograph or sphygmomanometer used in the physical examination, BrainLink uses the metallic copper sensor safe to human body to detect the bio-electricity signals on the epidermis of human body. The brainwave signals of human body are centered in the head, while the area that is the most beneficial to brainwave detection is located in the forehead without coverage of hair. Therefore, BrainLink uses a single-point metal sensor to collect the bio-electricity signals.

BrainLink will process these signals to some extent, e.g. clutter filtration, noise reduction and analytical calculation, and then send the analyzed brainwave state to iPad or other intelligent terminals via Bluetooth.

Ear clip plays a role of "sensing circuit". There are two sensors in the ear clip, one of which is reference electrode, and the other of which is grounded, the same as the clip at the ankle while electrocardiography. Cardio-electricity is the strongest bio-electricity signal in human body, so it can be accurately collected in a circuit crossing half of the body, while cerebro-electricity is much weaker, so it can be collected in a circuit crossing half of the head. The ear clip of BrainLink is precisely ergonomically designed, comfortable to wear, without causing any discomfort to the earlobe.

BrainLink uses the internationally popularized Bluetooth 3.0 wireless transmission standard protocol, and many Bluetooth headsets have also used the same wireless technology. However, the data size and power transmitted by BrainLink are much less than the audio and voice of general Bluetooth headsets. Therefore, compared to the commercially available Bluetooth headsets, BrainLink has nearly zero radiation.

BrainLink has passed the certification of Bluetooth SIG, FCC, CE, SRRC and other radio safety certification authorities, and has been authorized by MFi (Made for iPhone). The built-in lithium battery has also passed the UL1642 safety certification. The materials used by BrainLink are environmentally-friendly, recyclable, free from harmful ingredient, consistent with the international environmental protection ROHS certification.

No. BrainLink can detect the changes in the strength and frequency of brainwaves in the left forehead of the brain only. These changes can reflect different human brain states only, e.g. focused, relaxed, fatigued, nervous and anxious, and will not reveal the concrete thinking information. Therefore, BrainLink will not reveal the user's thinking information privacy.

No. BrainLink uses the un-embedding brain-computer interface technology to collect the brainwave bio-electricity signals on the forehead skin surface only via the sensor contact with the skin. BrainLink will not interfere, affect or even control the user's brain via any bio-resonance technology (e.g. Alpha acoustic wave or optical wave).

BrainLink trains the brain's self-state-regulating ability, a spontaneous regulating skill. Many Apps will offer some tips to control the brain states (e.g. auto-suggestion, imagination method, breathing regulation and Alpha acoustic wave resonance, etc.) You can pace yourself or develop new skills according to these tips. BrainLink can help you to validate whether the brain is really in the focused or relaxed state, and give the visual and acoustic feedbacks and tips by means of multimedia. Through these feedbacks and practices, you can gradually develop the self-regulating skills best fit for yourself, and then gradually consolidate these abilities through long-term training, thus flexibly used in the daily life and learning.

Everyone has different trigger points to enter the focused or relaxed state. However, BrainLink can help you to find your exclusive focused or relaxed "note" more scientifically and more rapidly.

BrainLink uses the application of cerebro-electricity feedback technology in the multimedia field. Many research institutions and universities at home and abroad have carried out scientific experiments on how this technology improves the human psychological health, and have proved that this technology can bring the improvement to different extents. The cerebro-electricity feedback technology has been always been widely used in the treatment of children hyperactivity, the most popularized method without side effect in addition to the drug therapy. In our opinion, this technology not only can be utilized in the treatment of children with hyperactivity, but also should be popularized to the public consumers to help more people to improve the brain self-control ability.

Many apps of BrainLink has the effect evaluation functions, e.g. the calendar in the "Mind Yoga" or the parent interface in the "Mind Ant". You can record your brainwave data for a long time with these functions to observe the change trends, and the effects will be clear at a glance. Meanwhile, the system will provide evaluations and suggestions based on the user performances. The parent interface also provides a ranking of cloud brainwave database, so that you can understand the ranking of your child in the focus among the nationwide children of the same age. You can rapidly understand the brain self-control performance levels of yourself and your child.

BrainLink trains a kind of spontaneous "proactive focus", different from the "passive focus" stimulated and induced by the outside world. Many educational experts think that the proactive focus is more important! In many BrainLink games, the user should proactively enter the focused state to pass the challenges and obtain the rewards. Difficulties will be gradually increased with the games, so the user should be more proactively focused and more rapidly for a longer time, thus the user's spontaneous focus will be gradually improved.

Any long-time use of tablet PC or mobile phone will cause adverse effect on the eyes. Therefore, we suggest that each continuous use time of BrainLink not exceed 30min. You can set the play time and the rest time on the parent interface of the games. Additionally, in part of relaxation game apps, the user will often close the eyes to relax, which will greatly reduce the eye pressure, and the long-time relaxation and meditation will be helpful for the brain health. Therefore, if you are worried about your child's vision or brain fatigue, you can encourage your child more to interact with the relaxation games (e.g. the relaxation mode in the "Mind Yoga" or "Think-tank Star Crisis").

A 1: Our apps are mainly used to train the focus and relaxation in the game-playing manner. What we advocate is the value proposition of "healthy brainwave and new family". Game & animation is one of our manifestation modes. We have developed different multimedia mind interaction experience, relaxation guidance and other apps specific to different ages, e.g. Meditation Garden, for the purpose of enabling the users to make their brainwaves healthier in a simple, convenient and educational manner.

A1: Simply speaking, our product can enable the users' brain to learn to relax and focus. At present, our company has the programs developed for the children aged 4~14. Nowadays, the children have heavy learning stress and learning burden. How to relax themselves in the heavy learning? How to focus under the heavy stress? I think these are the topics concerned by the students and parents. Based on the statistical analysis of data from our previous pilot projects, after trained by our training software system, many children’s focus has indeed strengthened. Additionally, we believe that in addition to the children, other remaining family members can also use our product to make some mindful parent-child interactions, because a healthy brainwave is beneficial and vital to everyone and his relatives and friends.

A2: Simply speaking, our product can enable the users' brain to learn to relax and focus. BrainLink translates the human brainwaves into the visible data map with the advanced technology to help the users to understand their focus and relaxation, thus improving their poor self-control.

A3: If old people use our product to do some brainwave control training for a certain time daily, it would be helpful for them. For example, it would be helpful to relieve the Alzheimer's disease.

A: Simply speaking, our product is to help the students to improve their self-focus and relaxation. Actually, these abilities exactly can urge them to develop good living and learning habits, e.g. listening carefully in class, sleeping on time, restricting the time to watch animation and finishing the homework on time; if a child can do these like an adult, will you still be worried about his poor academic results? For the children with psychological problems, we suggest them to receive the treatment from professional psychologist. If our product is used as adjuvant therapy, the result will certainly be better.

Brainwave (EEG), like the cardio-electricity (ECG) and myo-electricity (EMG), is a bio-electricity, produced by human organ. Brainwave is bio-electric current produced by connection and interaction between neurons.

Human discovered the brainwave (EEG) in 1920, and discovered the changes in the brainwave rhythms in the human states. Later, the brain science circle set these rules into a set of standards, forming the EEG today. Generally speaking, people are in the alpha and beta states when awake, and in the theta or delta state when sleep.

Alpha (8~13 Hz) is a relaxed state when people are consciously awake, e.g. walking in a park, doing yoga or closing their eyes meditatively. It is widely believed that this state can promote the physical health condition, particularly the sub-health condition of urban high-stress population. Alpha state can reduce the physical stress hormone secretion, and improve the insomnia, low immunity, obesity, hypertension and other sub-health conditions.

Beta brainwave is generally divided into low beta wave (13~17Hz, also called SMR wave) and high beta wave (18~30Hz). Low beta wave is the brainwave when people are in the working state, a focused state, where the limb movement is under control. High beta wave is the brainwave when the brain is in the stressed, nervous and excited state. If the brain is in this state, a lot of energy will be consumed, and the brain will feel fatigued, anxious and stressed. Beta brainwave is particularly important for people's working and learning performance. Therefore, cultivation and induction of beta brainwave in the childhood will be greatly helpful for the future growth of the children. If child cannot produce beta wave, there is probably a lack of certain nutrient elements during the brain development, resulting in attention-deficit hyperactivity disorder (ADHD).

Theta wave (Hz 3~7) is a brainwave between waking and sleeping. When our left brain is in the theta wave state, the left brain will be "closed", and the right brain will be "activated" to become active, clouding in consciousness, but the creative inspiration is endless. Theta is a state the artists and writers often pursue for, and people can reach this state under the effect of drugs. Of course, we can also reach this state naturally when we are meditating and deeply relaxed.

Delta (1~3Hz) is a state of deep sleep, which allows the body and brain to take full rest and get revitalized. Delta wave will also be produced when neonate brain is not fully developed.
