Set a timed profile
Timed profiles can be very useful in preventing missed calls. For example,
suppose you attend an event that requires you set your phone to the
Silent profile before the event starts, but forget to return it to Normal
until hours after the event is over. During this time, you’ve missed several
calls because your phone’s ringing tone was silent. A timed profile can
prevent this from happening by automatically returning your phone to the
default profile at a time you specify.
Note: Timed profiles can be set up to 24 hours in advance.
