About TAC-STIM
TAC-STIM™ transdermal vagus nerve stimulation (tVNS) enhances human performance by improving memory
retention, attention, and mood, accelerating training, and decreasing fatigue.
TAC-STIM tVNS delivers proprietary electrical signals via two small electrodes placed on the skin at the cervical
level. The electrical energy stimulates the vagus nerve, which triggers neurotransmitters in the brain.
NOTE: TAC-STIM is active for 36 months when turned on, and the session intensity increased past three.

Charging TAC-STIM
-Plug the charging cord into the back of the charging case and connect it to an electrical outlet.
-Place TAC-STIM into the charging case.
-“Ch” will appear on the display, indicating it is placed correctly and charging.
-Charge TAC-STIM for at least one hour prior to first use.
Cleaning TAC-STIM
-Clean TAC-STIM after each use by gently wiping the case and the stimulation surfaces with a soft, dry cloth to
remove leftover gel.
-Put the cap back on the product after use to protect the stimulation surfaces from dirt, debris, and damage.

1. Locate your vagus nerve.
1. Use 2 fingers to locate your pulse in the cervical region;
the vagus nerve is in the same area.
2. Make sure the application site is clean and dry.
3. Remove anything blocking the application site.
3. Administer the sessions.
7. Place TAC-STIM over the vagus nerve at the cervical region.
8. Increase the intensity level until you notice a slight muscle
contraction at the corner of your mouth.
9. TAC-STIM will stop automatically after 2 minutes.
NOTE: You will likely feel muscle contractions at the application site and
may experience a lip pull. These are normal and should stop after the
session is complete. If muscle contractions are too strong or
uncomfortable, try:
• Lowering the intensity level by pressing the bottom area of the
control button.
• Repositioning the electrodes on the neck over the pulse and
slowly increasing the intensity level again by pressing the top
area of the control button.
If the intensity level is still too strong, stop the session and turn
TAC-STIM off by pressing and holding the power button for 3 seconds.
NOTE: Additional gel may be needed between sessions.
2. Prepare your TAC-STIM.
4. Remove the cap.
5. Apply a pea-sized amount of the provided gel to the stimulation surfaces.
a. Not applying the gel as described may cause the session to be
uncomfortable or less effective.
6. Turn TAC-STIM on by pressing the power button. When TAC-STIM is ready for
use, it will beep once.

Warnings and Precautions
WARNINGS
Do not use TAC-STIM if:
-You have an active implantable medical device, such as a pacemaker, hearing aid implant, or any
implanted electronic product.
-You are using another product at the same time (e.g., TENS Unit, muscle stimulator).
-You are driving, operating machinery, or during any activity that may put patient at risk of injury.
-You are in the presence of strong electromagnetic fields, such as MRI scanners.
-You are in an explosive atmosphere or in the presence of flammable gas mixtures.
-You have an open wound, rash, infection, swelling, cut, sore, drug patch, or surgical scar(s) on the neck at
the application site.
-You have wet skin, are in the water, or just stepped out of the water (e.g., shower, bath, pool).
It is not recommended to use TAC-STIM:
-If you have had surgery to cut the vagus nerve at the neck as it may not be effective.
-If you are younger than 12.
-If you are pregnant or breastfeeding.
-More than 24 times a day.
PRECAUTIONS
-TAC-STIM should only be used as described in the User Guide.
-Only use a TAC-STIM-supplied conductive gel.
-Do not apply TAC-STIM across or through the head, directly on the eyes, covering the mouth, on the
chest, on the upper back, or over the heart.
-Do not use TAC-STIM if there are signs of damage or defects.
-Do not use if an error code is displayed on the screen when the product is turned on.
-Do not submerge TAC-STIM in water; it is not water resistant.
-Store in a safe location out of reach of children.
Potential Adverse Reactions
Users with sensitive skin may experience application site discomfort, irritation and/or redness. If you experience
light-headedness, dizziness, or chest pain, excessive skin irritation, local pain, face/head/neck area (including
toothache), muscle twitching, tingling, contractions, or other adverse reactions, DISCONTINUE USE. These reactions
typically resolve after the session is complete; however, if it persists after the session, consult your physician.
Troubleshooting
