Battery tips CAUTION! Batteries can be harmful if swallowed. If a battery is accidentally swallowed, seek medical attention immediately, or call The National Button Battery Hotline collect at (202) 625-3333. Always use the battery size recommended on your warranty card, or by your Audiologist or Hearing Care Provider, for your model for best performance. Remove the battery from your instrument when not in use. This prevents possible damage from expansion or leakage of the battery, if the instrument is not fully turned off. Always carry spare batteries in the event that your current battery goes dead. Place each spare battery in an individual, non-metallic container to prevent contact with other batteries or metal objects, such as keys or coins. Follow your local recycling rules for battery disposal.
Note: Do not throw used batteries into household trash. Return them to your Audiologist or Hearing Care Provider for environmentally correct disposal.
WARNING: Risk in explosive environments, e.g., mining areas! Dont use your hearing instruments (and remote control) in areas where there is a danger of explosions. Using a remote control If you have an optional ePocket remote control, the battery status can be checked using the battery read out function. For further information on the ePocket, speak to your Audiologist or Hearing Care Provider or refer to the ePocket instruction manual.

Using the charger

If you have the CENTRA Active optional charger, refer to the charger instruction manual for operating instructions. Use only the rechargeable batteries with your CENTRA Active instrument that are delivered with the charger or available through your Audiologist or Hearing Care Provider. The lifetime of a rechargeable battery is approximately one to two years, depending on individual use.
