Recovery following storage/shipping
Condensation can occur if a device that is stored or
shipped at a low temperature is brought into a warm
room. To prevent damage, wait until no more
condensation is visible on the surface of the device
before powering it up. Do not operate the device until it
has reached its specified temperature range and wait
until it has cooled down if the device was stored at a high
temperature (see „Ambient temperature", page 38).
