Q: I am having trouble pairing the Cervella to my smartphone.
A: Ensure that you have Bluetooth enabled on your smartphone and that Bluetooth settings on your smart device allow new incoming connections. Ensure that there are no paired devices with your smart device. Always pair the Cervella main device first from inside the Cervella app and then pair the Cervella headphones with your smart device second. If you have accidentally paired the headphones first, unpair them, and then pair the Cervella device first inside the app, and then pair the headphones.
Q: Why is it that when I press, “START” in the timer circle, the timer does not start?
A: This is usually caused by the fact that the ear cushions are not making tight contact with your skin, you did not apply the conductive gel, the device is not paired with your app, or the Cervella and headset are not connected via the white electrode cable.
Q: How do I know that the current is flowing and the Cervella device is operating properly during treatment?
A: There are two indicators. First, the LED on the Cervella box will be blinking BLUE. Second, the counter on the Cervella app will count down treatment time. If the LED is solid blue or the counter is stopped, you do not have a good contact between the gold electrodes of the headset and your mastoid area or you do not have the device connected properly.
HINT: you can test the operation of the Cervella system by starting the treatment and just touching the two ear cushions together. You should see the LED blinking blue and timer counting down and stop as soon as you separate the ear cushions indicating a break in the connection.
As always, please resist increasing current intensity level as stronger does result in faster or better clinical outcomes. Always use your Cervella at the lowest setting where the tingling sensation is just barely perceptible. Use small a small amount of gel. You can see the proper way to apply the gel by watching the Cervella set-up and operation video.
Q: How do I know that my Cervella device is charging properly and holding charge?
A: When you charge your Cervella device, the Cervella LED should blink RED and turn solid GREEN when charge is completed. If you were to plug the Cervella into charger again after full charge, you will see the LED blinking RED again making you think the device is not holding charge. However, this is done on purpose in order to extend the lifespan of the battery inside the Cervella device. You see, the Li-Ion batteries do not like to be charged to 100% so we purposely do not "top off" the battery charge so that we can extend the battery number of charge cycles. That is also why when you go to the Pairing menu in the Cervella app after full charge you can often see the Cervella charge level to be 99% instead 100%. Your device is charging and operating exactly as intended.
Q: Why should I wet the ear cushions with conductive gel or water?
A: The ear cushions contain electrodes that are seamlessly integrated into to the ear cushions. The electrodes are conducting the electric current to your brain via the skin interface. In order for the electricity to flow efficiently, the skin and electrode interface must be of as low resistance as possible. The conductive gel lowers the resistance for electricity that allows for better current flow resulting in more comfortable and more effective treatment.
Q: What should I do if I experience stinging in the area of contact between the headset ear cushions and my skin?
A: Ensure that you are using conductive gel (best) or water to wet the contact patch area. Also, make sure that both ear cushions are in tight contact with your skin and the skin is clean of oil and make-up. Remove any earrings, piercings or jewelry before starting treatment. Lastly, reduce treatment intensity until the stinging sensation is slightly noticeable but never uncomfortable. Using Cervella at high current levels and without conductive gel or water at the contact patch interface may cause skin irritation.
Q: How should I clean the Cervella?
A: You should wipe the ear cushions using a lightly damp cloth after each use and let air dry. You can also use 70% isopropyl alcohol to disinfect the ear cushions and headband after use. Never use chlorine or aggressive chemicals cleaners to clean the Cervella.
Q: What do the various colors mean for the LED indicator on top of the Cervella?
A: The tri-color indicator LED shows you the status of the Cervella device. The LED will blink blue during treatment and solid blue when the treatment is paused. Red means that the Cervella needs to be recharged. Green means that Cervella is charged and is successfully paired with the app. For other colors, please refer to the TABLE 1 in the manual.
Q: Can I use my smart device for both Cervella treatment and to stream audio to the headset?
A: Absolutely. Please remember, however, that you will establish two (2) independent Bluetooth connections: the first connection will be between the Cervella device and the Cervella App on your smart device, and the second connection will be used to stream audio from your smart device to the Cervella headphones. Note: avoid connecting additional Bluetooth devices to your smart device in order to ensure uninterrupted audio streaming experience.
Q: What are the requirements for the Bluetooth communication?
A: In order to ensure uninterrupted communication between the Cervella App and the Cervella device, keep the maximum distance between the controlling device and Cervella within 15ft (5m) and keep the device away from sources of strong electromagnetic fields such as cell phones, WiFi routers, microwaves, and radio transmitters. If you are planning to use the audio feature of the Cervella headphones, also ensure that the audio source and the Cervella headphones are not separated by more than 15ft (5m). When this range is exceeded, you may see an error, “The connection has timed out unexpectedly” and the Cervella and App will stop. To restart treatment, reconnect Cervella by touching the timer circle on the app which will state, “Touch to Connect” and restart the treatment.
