Charge the hearing instruments for at least 15 minutes before a first fitting session.

Fully charge the hearing instruments before delivery to the client. A full charging cycle takes approximately 4 hours.

General warnings

REXTON M-CORE SR Hearing Earphone User Guide  & troubleshooting 7

WARNING
A power cell (lithium-ion rechargeable battery) is permanently built into the hearing instrument. Incorrect use of the power cell or the hearing instrument can cause the power cell to burst. Risk of injury, fire or explosion!

  • Follow the safety instructions for power cells in this section.

7

Defective power cells
In case you think the power cell is defective comply with the following steps:

  • Place the hearing instrument into the charger. If you get a red LED then the power cell is defective.
  • Perform visual inspection of the hearing instrument.
    The test is considered failed if it has any of below criteria:
  • There is physical sign of deformation caused by bloated lithium power cell inside.
  • There is visible leakage from the lithium power cell.
  • Product is generating heat on its own or hot to the touch.

If any of the test steps failed, consider the power cell defective. Due to safety concerns the hearing instrument cannot be shipped anymore. Please record the serial number of the hearing instrument, take a photo of the damages, and consult with Sivantos Customer Service team before disposal of the product according to local regulations.
