During use
During normal operation the temperature should not exceed the limit values of +5°C (+41°F) – +40°C (104°F)
at a relative humidity range of 15% to 90%, non-condensing, but not requiring a water vapor partial pressure
greater than 50hPa. An atmospheric pressure between 700hPa and 1060hPa is appropriate.
While charging, the ambient temperature should be within the limit values of +5°C (+41°F) – +35°C (+95°F).
Charging you hearing aids at ambient temperatures over +35°C (+86°F) may lead to extended charging times.
NOTE: During use, your hearing aids may reach temperatures up to +43°C (+109°F).
During transport or storage
During transport or storage, the temperature should not exceed the limit values of:
• -25°C (-13°F) – +5°C (41°F)
• +5°C (+41°F) – +35°C (+95°F) at a relative humidity up to 90%, non-condensing
• >+35°C (+95°F) – +60°C (+140°F) at a water vapor pressure up to 50hPa.
Warm-up time: 5 minutes.
Cool-down time: 5 minutes.
