sleep mode for a TE series endpoint?

Hello Dear Friend :

Please to apply the following steps:
On the web interface of the endpoint, choose System Settings > General > Power management. Enter sleep mode: period after which an endpoint enters the sleep mode (when the sleep conditions are met) if no operation is performed.
Default value: 10 minutes The endpoint wakes up from sleep mode once any operation is performed on it.
If this parameter is set to Never, the endpoint will never go to sleep automatically.
To directly place the endpoint in sleep mode, press the power off key on the remote control and select the sleep option.

Thank you.
