4. Charging the CROS device
Low power: You will hear two beeps in the hearing
aid when the battery is low. You will have
approximately 60 minutes before you have to charge
the CROS system (this can vary, depending on the
hearing aid or CROS device settings). After this time
the CROS system automatically shuts down.
The CROS device contains a built-in and non-
removable rechargeable lithium-ion battery.
Before using your CROS system for the rst time, it
is recommended to charge it for 3 hours.
The CROS system must be dry before charging,
see chapter 18.
Please ensure to charge and use the CROS system
within operating temperature range: +5° to +40°
Celsius (41° to 104° Fahrenheit).
For more information on how to charge the hearing
aid part of the CROS system, refer to the user guide of
the hearing aid.
