Charging The Hearing Aids - Sonova Slim L-R Series User Manual

4. Charging the hearing aids

Low power: You will hear two beeps when the
hearing aid battery is low. You will have
approximately 60 minutes before you have to
charge the hearing aids, after this time the hearing
aid automatically shuts down (this can vary,
depending on the hearing aid settings).
The hearing aid contains a built-in and non-
removable rechargeable lithium-ion battery.
Before using your hearing aid for the first time, it
is recommended to charge it for 3 hours.
The hearing aid must be dry before charging, see
chapter 18.
Please ensure to charge and use the hearing aid
within operating temperature range: +5° to +40°
Celsius (41° to 104° Fahrenheit).
