# Safety Precautions

* EPOC Flex is a consumer product; it **is not** intended to be used as a medical device or in hazardous environments.
* EPOC Flex is designed for use at room temperature; rapid changes in temperature will affect the performance of the amplifiers and increase the noise floor.
* EPOC Flex uses saline based sensors. Every effort has been made to stop water entering the headset and protect the electronics inside.  However, the headset is not waterproof. Do not submerge your headset in water.
* **WARNING:** EPOC Flex is powered by a lithium polymer battery that is rated for operation in <50°c environments. It **is not** user replaceable. If you suspect that there is a fault with the battery, please contact EMOTIV Support.
* **WARNING: Do not** open the headset enclosure. Doing so will void the warranty and can damage the headset.
* ‌**WARNING: Do not wear** EPOC Flex while charging the device. If you want to operate while tethered EPOC Flex is compatible with Extender.

**Précautions de Sécurité**

* EPOC Flex est un produit de consommation; **il n'est pas** destiné à être utilisé comme appareil médical ou dans des environnements dangereux.
* EPOC Flex est conçu pour une utilisation à température ambiante; des changements rapides de température affecteront les performances des amplificateurs et augmenteront le bruit de fond.
* EPOC Flex utilise des capteurs à base de solution saline. Tous les efforts ont été faits pour empêcher l'eau de pénétrer dans le casque et protéger l'électronique à l'intérieur. Cependant, le casque n'est pas étanche. Ne plongez pas votre casque dans l'eau.
* **AVERTISSEMENT:** EPOC Flex est alimenté par une batterie au lithium polymère conçue pour fonctionner dans des environnements <50°c. Il **n'est pas** remplaçable par l'utilisateur. Si vous pensez qu'il y a un problème avec la batterie, veuillez contacter le support EMOTIV.
* **AVERTISSEMENT: n'ouvrez pas** le boîtier du casque. Cela annulerait la garantie et pourrait endommager le casque.
* ‌**AVERTISSEMENT: ne chargez pas** l'EPOC  lorsque vous portez l'appareil. Si vous voulez fonctionner alors que l'EPOC Flex connecté est compatible avec Extender.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://emotiv.gitbook.io/epoc-flex-user-manual/epoc-flex/safety-precautions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
