During use
During normal operation the temperature should not exceed the limit values of +5 °C (+41 °F) to +40 °C (104 °F),
at a relative humidity range of 15% to 90%, non-condensing, but not requiring a water vapour partial pressure
greater than 50 hPa. An atmospheric pressure between 700 hPa and 1060 hPa is appropriate.
While charging, the ambient temperature should not exceed the limit values of +5 °C (+41 °F) to +30 °C (86 °F).
CAUTION: 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) to +5 °C (41°F)
•
+5 °C (41 °F) to +35 °C (95 °F) at a relative humidity up to 90 %, non-condensing
•
>+35 °C (95 °F) to +60 °C (140 °F) at a water vapour pressure up to 50 hPa.
Warm-up time: (from -25 °C (-13 °F) when placed at 20 °C (68 °F)): 15 minutes.
Cool-down time: (from +60 °C (140 °F) when placed at 20 °C (68 °F)): 20 minutes.
