The Biotuner operates from a regular 9-volt alkaline battery. One may also use a rechargeable NiMH battery. The underlying frequency for all six operating modes is 1,000 Hz. (+/- 1 Hz.) pulse-modulated by 111.11 Hz. (+/- 1 Hz.). Waveforms are Quartz Crystal-Controlled for precise frequency output. There are also a broad range of frequency harmonics delivered in each pulse. Pulses are Bi-Phasic (AC) with no direct current (DC) or offset bias. Output is transformer coupled so that no DC can appear at electrodes. The algebraic sum of positive and negative-going pulses is zero. The BT-9 feature a constant voltage ouput so you don't need to keep turning up the voltage dial as the battery drains.
A renowned Los Angeles physicist developed the original BT-5 model in 1983. This unit had a fixed output setting of 1,000 Hz., modulated (pulsed) at 111Hz. (plus hundreds of frequency harmonics). In 1989, we introduced the BT-6 model with the additional 7.83Hz. Schumann Resonance (Earth Resonance Frequency) and a 0.5 Hz., ON/OFF cycle. This is included in our current model BT-9 as well. Many customers familar with the concept of Schumann Resonance, have asked if the 7.83 Hz. setting will stimulate psychic or spiritual states of consciousness. To our knowledge, based upon 30 years of marketing the orignal model BT-5 through the current BT-9 Bio-Tuner, there is no psychic or paranormal effect from using this particular setting.
Proper nutrition is important when using the BT-9. Individuals who have been stressed out for years (depression, post-traumatic stress syndrome, etc.) will see a much better result from using the Bio-Tuner if they take some steps to improve their over-all health and support the brain with proper nutrients to support the production of neurotransmitters. There are many good nutritional support formulas available from your health food store or on the internet. Likewise, good quality amino acid formulas are readily available.

What Setting Should I Use
The Biotuner uses a specially designed electronic waveform that contains hundreds of frequency points or harmonics. This eliminates the need for individual frequency adjustments as a complete balancing effect is given without the need for constant manual adjustment. When choosing a setting, it is important to note that due to the internal programming of the BT-9 ALL of the settings share an underlying frequency of 1,000.00 Hz., which is then pulsed out or interrupted by the 111Hz. pulse repetition rate, (along with the hundreds of frequency harmonics). So, all six settings share this feature in common. So, you should expect very positive results regardless of the setting that is selected. Having said that, feel free to test out all six of the Biotuner settings to see which one feels best for you.
Setting number 1 is the original setting of the first BT-5 unit from the early 1980's. At that time, the unit only had the ON and OFF switch and customers were reporting great benefits from this. Settings 2 and 3 were added to the BT-6 model and gave an extra element of voltage modulation to the basic output. In other words, the voltage is "Pumped Up and Down" at the 0.5 rate (setting 2) or the 7.83 rate (setting 3). The body is very sensitive to many types of rhythms and pulsations, so the voltage modulations of 0.5 and 7.83 add an extra dimension of relaxation signals to the body. A frequency of 0.5 is related to the human Delta brainwave range and the 7.83 is related to the Alpha brainwave range.
Selectable Output Settings
Note that settings 1, 2, 3, have a pulse duration of 550 microseconds and settings 4, 5, and 6 have a pulse duration of 220 microseconds. This represents the active ON time of the pulse. We do not have any published research that would support the use of one pulse width setting over the other. The underlying waveform of the BT-9 is the same, regardless of the setting you select. This means that any of the six settings will provide a broad spectrum of frequency harmonics and all of them will work! Just find the setting that feels best to you.
(1) 111.11 Hz - this was the setting for the original BT-5 model from 1983. It includes hundreds of harmonics. Many users find this setting to be more energizing. This pulsation frequency is actually present in all six of the BT-9 settings.
(2) 1 sec. ON / 1 sec.
OFF - this 0.5Hz. voltage modulation corresponds to the low Delta brainwave frequency. This frequency, in terms of EEG brainwave, is associated with deep REM sleep.
(3) 7.83 Hz - this was the favorite setting of the inventor. This is also known as the Schumann Resonance frequency ( the Earth Resonance Frequency or Earth's Brainwave), due to the resemblance to the human Alpha brainwave pattern. This setting may help to synchronize the energy levels of the left and right brain EEG patterns. As a pioneer of EEG bio-feedback instrumentation, the inventor tested numerous healers, shamans, Hawaiian Kahunas, dowsers, etc. and found that all of them exhibited high levels of brainwave activity in the 7.83Hz. frequency when they were engaged in actual healing activity.
The 7.83 Alpha frequency is also associated with increased creativity, superlearning, memory improvement, intuitive insights and more. We have not found this to produce paranormal or psychic abilities. This type of entrainment of the brain would be more likely with a magnetic pulse device that operates within the human brainwave frequency range.
What is the Best Time of Day to Use BT-9
It is alright to use the brain tuner any time of day. However, due to the body's daily variations in Bio-rhythms, blood sugar levels, etc. your responses to the brain tuner may vary according to the time of day it is used. For example, some individuals using BT-9 near their normal bed time, may find that it gives them a lot of extra energy and they do not feel tired. In this case, try using the unit earlier in the day, or try using the 0.5 Hz. setting. It is important to use the BT-9
each day for 2 to 3 weeks in order to achieve the maximum benefits.
There is no need to repeat the entire 2 to 3 weeks if you happen to skip
a day or two. Following the initial series of sessions, BT-9 may
be used on occasion as desired to maintain the initial improvements.
For example, memory improvements may maintain up to 1 year before additional
sessions are necessary. Other gains may be more temporary and require
more frequent reinforcement. Individual results will vary.
How Fast Will I Notice Results
Typically, one should use the BT-9 once a day for 30 to 60 minutes per day. This should be kept up for two to three weeks. Most people will begin to notice a greater level of relaxation and stress release by the second or third session. Sometimes people are a little bit out of touch with their own internal process and others around them actually become aware of the changes before the user is aware of them. As an example, we had a customer years ago who said he was looking for an alternative to alcohol in order to help him relax after a stressful day at work. He purchased a Biotuner and after a month, he called asking to return the unit for a refund, as it was not doing anything for him. Upon questioning how he was dealing with his drinking problem, he stated that he hadn't had a drink in several weeks. When asked if he related this to using the Biotuner, he answered that he simply lost the desire to drink any more, so he didn't. Needless to say, he ended up keeping the Biotuner as a valued relaxation tool. Now, this is not to say that using a Biotuner has anything to do with drinking alcohol. The point is rather, that when our body energies are more in balance, many beneficial changes happen in the most natural way.
Possible Side Effects
Vivid or Lucid Dreaming - over the years, we have observed that some individuals experience very enhanced dreams during the first week or two of using the BT-9. This is not permanent and usually does not last more than a few weeks. A very small number of individuals may experience a mild headache the first few times of use. This has been noted in the historical literature for this type of electronic instrument. If you wish to discuss any possible side-effects, we will be happy to address your concerns.
Earclip Sensitivity - some individuals may be very sensitive to the electrical stimulus of the earclips on the earlobes. Start out with the intensity dial at a low level the first few days. There is no need to "crank up" the intensity levels in order to achieve beneficial results. It is very normal for the body to adapt or accommodate to the stimulation. After a few minutes, you may not feel the electrical stimulation on the skin. If the intensity dial is turned up, then you will feel the stimulation once again. It is not necessary to continually increase the stimulation levels throughout the session. In some very sensitive individuals, turning the power level all the way to maximum could irritate the skin. Remember, when it comes to the intensity setting, more is not necessarily better. Before using the Biotuner, remove any earrings and remove any body oils, makeup, etc. from the area. This will produce a better electrode contact with the skin.
Warranty and Refund Information
BT-9 has a three year warranty and a limited 30 day money back guarantee. If the unit is returned unused within the first 30 days, there is a full refund (not including shipping charges). If the unit has been used, the 30 day refund is subject to a 20% restocking charge to cover replacement of accessory parts.
Personal note from Volker Risto - owner of this website: my introduction to the original inventor goes back to 1985, when I first attended one of his lectures in Santa Monica, California. Like everyone in the room, I was captivated the fascinating information he had to share. He was highly intelligent, articulate and engaging while still making room for humor and personal stories. It was soon after that when I had an opportunity to help him market his products. This developed into a memorable and close relationship that endured until his passing on June 23, 2002. Among my fondest memories were the years of travelling around the country with this inventive physicist and the owners of Sota Instruments to numerous Health Expos and Science Conventions. The inventor of the original BT-5 was a unique personality and a great friend; an unforgettable genius who left behind him a legacy of hope and healing for millions through his great compassion and creativity. Note that the omission of naming the inventor of this line of instruments is required in order to maintain our ability to provide you this wonderful line of products today, and into the future.
