Use the N-8000 software* to perform settings. Set up the same
items as performed to the N-8050DS since the N-8050SB is
handled as the N-8050DS on the software.
The call button and status indicator operations are exactly the
same as those of the N-8050DS.
For settings, functions, and operations, read the descriptions
about the N-8050DS in the N-8000 Series instruction manual.

•Speaker opening ratio should be 15% (Example: ø4 mm x 9 holes) as a
guide.
•Keep the board from coming in contact with the speaker to avoid short-
circuit between them.
•Make a microphone opening with the microphone rubber's inside diameter
(ø4.5 mm), and position the microphone in the way that its center comes to
the opening center.
•Never install them as shown below. Doing so may cause the speaker
sound to enter the microphone.
