When set to On, the base and 
handset ringer volumes (on 
all handsets registered to the 
base) will be set to Off. The 
handset backlight will not come 
on when the phone rings and 
the only tones that the handset 
will emit are the battery low 
and out of range warnings. The 
base call screening volume and 
message alert will also be set 
to Off.
You can set Do not disturb to 
On or Off.  The default setting 
is Off.
When set to On, the idle screen 
will display 
DO NOT DISTURB 
instead of the number of 
missed calls or the handset 
name if there are no missed 
calls presented.
Please note, other products 
connected to the line are not 
compatible with this feature 
and will still ring.
