Contraindications

Because no controlled tests or studies have been run on these populations in conjunction with the BioCharger, the below items need to be followed and observed:

• Individuals with cardiac pacemakers, insulin pumps, MUST sit at least 6 feet away from your BioCharger. The other thing to consider is the FCC also said it is the first generation of pacemakers that are an issue. Since then they've figured out how to properly ground the newer devices so it's not an issue.
•  
• If a person has a hearing aid, it is best to remove it prior to the BioCharger session. If it is unremovable, then it is recommended to sit at least 4-6 feet away from the BioCharger to minimize any interaction
• 
  For individuals that are known to have photosensitivty (I.E. Photoconvulsive Response, Epilepsy, Migraines caused by Photosensitivity), we recommend using the BioCharger without the plasma tubes installed, since the strobing nature potentially could cause an episode. Another option is to wear a suitable eye mask (sleeping mask that shuts out all light) during the session. As everyone is unique, we advise seeking advice on what triggers an episode and take this into consideration prior to making the decision to use the BioCharger in this case. 
• 
  Women who are pregnant should NOT use your BioCharger.
• 
  Children under the age of eighteen (18) years old MUST be supervised by a parent or guardian during a BioCharger NG session.
• 
  Individuals with chemotherapy ports that are metal based should NOT use the BioCharger within 6 feet radius from the unit. Outside of that range reduces the intensity enough to allow usage, even with a port installed. 
• 
  Individuals with metal plating in their heads should NOT use your BioCharger NG.
