Flame retardant engineering thermoplastic
Operating temperature: 32°F to 104°F (0°C to 40°C
Charging temperature: 41°F to 95°F (5°C to 35°C)
Operating humidity: 5 to 93% non-condensing
Storage and transport temperature: -4°F to 122°F (-20°C to 50°C) for up to
24 hours
Storage and transport temperature: -13°F to 158°F (-25°C to 70°C) for
greater than 24 hours
Note: Storing the Astral device at temperatures exceeding 122°F (50°C) for
extended period of time may accelerate battery aging. This will not affect
the safety of the battery or device. Refer to Using the internal battery (see
page 41)
Storage and transport humidity: 5 to 93% non-condensing
It takes 40 minutes* for the device to be ready for use on a patient when
removed from storage at the minimum long term temperature and at an
ambient temperature of 68°F (20°C).
*Assumes that the device is connected to an external AC power.
It takes 60 minutes for the device to be ready for use on a patient when
removed from storage at the maximum long term temperature and at an
ambient temperature of 68°F (20°C).
