Temperature-Related Alerts
The hotspot is designed to work over a wide temperature range. (For information, see
Environmental Specifications on page 63.) The hotspot shuts down automatically if it goes
out of the supported temperature range.
Move the device to an area where the temperature is more suitable and, if the hotspot is too
warm, make sure that the area is well ventilated and air can circulate around the device.
Note: The battery might not recharge if the hotspot is outside the operating
temperature range.
