What is the BioTransducer® Pro?

BioTransducer® Technology provides no-touch, painless therapy. The Tennant BioModulator® transmits frequencies and voltage that the BioTransducer® delivers on a carrier wave into the tissue, through skin and bone. Using the BioTransducer® to deliver the frequencies and voltage speeds up therapy time.

The BioTransducer® is not a laser. The BioTransducer® can be used through clothing allowing the BioModulator® therapies to be delivered anywhere on the body without the need for direct skin contact.

Backed by science.

Dr. Tennant has dedicated his life to using his Tennant Devices to help his patients get well, and he has the clinical studies to prove it.

"One of my primary missions is to research and share my findings and enable others to educate themselves and discover answers to their unique health-related questions through wellness.” – Dr. Jerry Tennant

What does the BioTransducer® Pro feel like?

Some users experience a subtle tingle or sensation of warmth from the BioTransducer®. Most people don’t feel any sensations when using the BioTransducer®. You may feel initial apprehension about providing therapy to yourself or others. When you carefully follow the instructions and directions, there’s no need to be concerned. The devices and therapy steps were created with the knowledge that application will be general and does not have to be precisely aligned with any given point of the body. Even if you are providing the therapy to a different area than intended, it is not harmful and, in most cases, will still benefit you.

How do I use the BioTransducer® Pro?

Setting Up Your BioTransducer® Pro

Connect the USB cord to your BioTransducer® Pro and the A/C adaptor to charge

• It takes 6 hours to charge to full capacity and therefore should be charged overnight.

• One charge lasts 3 days, depending on use

• It is best to treat it like a cell phone, don’t run the battery completely down

PLEASE NOTE: Prior to using your BioTransducer® Pro for therapy, you must balance the polarity of your body. Refer to the Daily Protocol Guide for instructions on balancing polarity.

1. Connect the BioTransducer® to the Tennant BioModulator® with the connection wire. Use care when plugging the wire into the port on the BioModulator®. You can cause damage to your BioModulator® if it is knocked or bumped when plugged in. It is very important to remove the plug when not in use.

2. Turn on your BioModulator® (Pro or Plus).

3. Set the mode.

For BioModulator® Plus:

• TEN-8 for pain and inflammation related to muscle, bone, ligament and tendons. 

• INFINITY for all other issues related to organs and general health. 

• INFINITY for eye treatment.

For BioModulator® Pro:

• TEN-8 for pain and inflammation related to muscle, bone, ligament and tendons. 

• INFINITY for all other issues related to organs and general health. 

• VA-STEP for eye treatment. 

4. Adjust the power by pressing the + and – buttons. Since there is no skin contact you may increase the power as high as you want when using it on the body. When using it on the eyes set the power as is indicated in the eye treatment section (pg 7). 

5. Point the BioTransducer® at the area of concern, holding it between 1⁄2 an inch to 3 inches away from the body. (Please note: If you rest the rubber cap against the skin, you may have an allergic reaction to the rubber.) 

6. As a general guideline, therapy times are flexible just as they are when using the BioModulator® alone. 

For example:

a) 5 – 15 minutes for minor issues and for general use. 

b) As long as needed for more serious conditions. 

Tip: Therapy can continue for several hours when you mount the BioTransducer® to a mic stand and position it on the area of concern. See pg. 9 of the Quick Start Guide for caring for your batteries when doing longer therapy sessions. 

What is the difference between the BioTransducer® Crystal Wave and Pro?

If you are familiar with our BioTransducer® Crystal Wave, you know that it is powered solely from the BioModulator®. The BioTransducer® Pro is much stronger, therefore requires the additional power from the internal lithium battery. Be sure both the BioTransducer® Pro power and the BioModulator® are turned on when you are doing treatments. 

What is Dr. Tennant's Daily Protocol?

NOTE: You must have a BioModulator® device to complete this protocol.

This daily protocol will help balance and prepare your body so it can properly receive and use the voltage provided by your BioModulator® device for healing. This is accomplished by waking up and “activating” your organ systems, resetting your polarity so electrons flow correctly, balancing your autonomic nervous system, and recharging your whole body.
