Operating environment
Avoid environments in which there is dust, damp, dirt, or
magnetic fields. Using the device in these environments may
cause it to malfunction.
Do not use your device during thunderstorms to protect your
device against any danger caused by lightning.
Ideal operating temperatures are 0°C to 35°C. Ideal storage
temperatures are –40°C to 70°C. Extreme heat or cold may
damage your device or accessories.
Do not expose your device to direct sunlight (such as on a car
