Philips SE8881B-23 - Manual (Page 5)

Silent mode
By switching on silent mode, the ringtone will be disabled during the
times you specify, which is ideal when you want to sleep through the night
uninterrupted. The silent mode can exclude important contacts such as
close family members or friends.
Personalized ringtone
The S9 and S10 can convert ringtones from any MP3 file and come with
10 high quality ringtones pre-loaded.
Call barring
Call barring blocks outgoing calls to certain numbers, such as undesirable
area codes or phone numbers.
Call blocking
Call blocking silences the ringtone for callers on a blacklist or, if desired, for
any anonymous incoming call. This protects your privacy by preventing calls
from telemarketers or people you don’t know.
