**BioCharger Proximity & Safety Guidelines**

\- **Medical implant devices with electronics that cannot be turned off or removed** - e.g. cardiac pacemakers, defibrillators, insulin pumps, glucose monitors, spinal stimulators, and some types of hearing aid. Our recommendation is to start at least 6 feet away and gradually move closer only if comfortable.  If you notice any discomfort, move back.  Never sit closer than 3 feet.

Passive metallic implants anywhere else - shoulder, hip, knee, dental, etc - are acceptable and have never presented any problems, but we prefer to err on the side of caution when it comes to the heart and brain.

\- **Metallic** chemotherapy ports (*plastic/synthetic ports are acceptable*). 

Individuals with plastic chemotherapy ports can safely use the BioCharger NG, but a person with a metal chemo port should start at least 6 feet away and gradually move closer only if comfortable.  If you notice any discomfort, move back.  Never sit closer than 3 feet.

 During infusion chemotherapy, the person should refrain from using the BioCharging the day of and the day after infusions. For daily oral chemotherapy , we recommend using the BioCharger 3 hours after taking the chemotherapy pill.

\- Individuals with **epilepsy** or a **photosensitive condition** should wear a mask over their eyes or face away from the machine during operation, due to the flashing/strobing lights. Alternatively, the spectrum tubes could be removed entirely. 

\- There are no controlled, clinical studies with **pregnant women**, and we advise pregnant women do NOT use the BioCharger for that reason.

\-**Metallic plate/mesh/implant** in the **skull** must NOT use the BioCharger.

\- There is no minimum age, but **children under eighteen** require adult supervision and we advise small children be positioned further away in the 3-6 foot (0.9-1.8 meters) range.
