and need a minute or two
to fully charge.

To maximize sound
quality and extend the
life of your hearing aid,
follow these simple steps:
1. Wipe your hearing aid daily with a tissue or cloth to keep free of
dust and debris.
2. Clean the invisitube periodically. Remove the earbud, and insert
the thin end of the cleaning brush into the tube to remove any
soil or debris from the tube. Note: for optimum performance,
replace the invisitube and earbud every three to six months.

cleaning brush to remove any lint or debris from the microphone
openings.
4. Avoid physical shock to the hearing aid, such as dropping on a
hard surface, or dropping something heavy on the device.
5. Avoid exposure to extreme heat or moisture. Use the supplied
carrying case to keep the hearing aid covered when not in use.
