The device may be too hot. In this case, the integrated over-
heating protector prevents the SX682 WiMAX from being
damaged. If the temperature rises, the SX682 WiMAX auto-
matically reduces data transfer to a minimum. When the tem-
perature exceeds the critical value, the SX682 WiMAX
switches itself off.
Wait until the SX682 WiMAX has cooled down.
