• You can use the Wi-Fi hub only when you connect the Wi-Fi hub to an adapter.

If the Wi-Fi hub’s temperature exceeds 55 °C, the Wi-Fi hub’s internal fan will automatically activate. If the Wi-Fi hub overheats for a prolonged period, the Wi-Fi hub may automatically turn off or reset. When this happens continually, disconnect the adapter from the Wi-Fi hub and contact a Samsung™ Service Center.

• To save energy, unplug the adapter when not in use. The adapter does not have apower switch, so you must unplug the adapter from the electric socket when not in use to avoid wasting power. The adapter should remain close to the electric socket and be easily accessible while using it.
