60 minutes before you have to charge the hearing
aids (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 rst time, it
is recommended to charge it for 3 hours.
The hearing aid must be dry before charging,
see chapter 16.
Please ensure to charge and use the hearing aid
within operating temperature range: +5° to +40°
