2.6. Environmental Requirements
• The Notebook is most reliably operated at an ambient temperature
between 5° C (+41° F) and 30° C (+86° F) and at a relative humidity
between 20% and 80% (without condensation).
• When powered off, the Notebook can be stored at temperatures
between 0° C and 60° C (+32° F and 140° F).
• During a thunderstorm, disconnect the mains plug and the anten-
na plug. For extra safety, we recommend using an overvoltage pro-
tection device to prevent the Notebook from sustaining damage
as a result of power surges or lightning strikes.
• After transporting the Notebook, wait until the device has reached
room temperature before switching it on. Large changes in tem-
perature or fluctuations in humidity can cause moisture build-up
within the Notebook due to condensation. This can cause an elec-
trical short circuit.
• Keep the original packaging in the event the device needs to be
sent in the post.
