An Overview of Your Phone
If your phone is inactive (idle) at the sleep time, you see a message to remind you that your phone is
going to power down. To keep the phone active, press any key on the phone. If you do not press any
key, your phone powers down.
If your phone is active (for example, on a call), your phone waits until it has been inactive for a period
of time before informing you of the pending power shutdown. Before the shutdown happens, you see
a message to remind you that your phone is going to power down.
At the scheduled time, your phone powers up. To wake up the phone before the schedule time, contact
Wake and sleep times are also linked to the configured days that you normally work. If your
requirements change (for example, your work hours or work days change), see your system
administrator to have your phone reconfigured.
