Tips
When the HW-02G is in use for an extended period of time, it will become warm and may
overheat. Should this happen, the HW-02G will automatically close the network connection
and turn off to protect itself from damage. If this occurs, place the HW-02G in a well ventilated
space to allow the heat to dissipate, then turn it on and continue to use it as normal.
If you are unable to use the HW-02G as normal, try the following:
Consult the user manual on the web management page.

Restart the HW-02G.

Restore the HW-02G to the factory settings.

Consult your operator.
