5.2. External Dial Switch Connection
Connecting external switches such as
footswitches permits them to perform the
same operation as the dial keys "7," "8,"
"9," and "C".
An electrical current of 1 mA flows through
each contact.
Note
The cable length from the external switch
should not exceed 3 m.
Connect a keyboard of
which circuit
configuration is as
shown in the figure.
An electrical current of
1 mA flows through

INSTALLATION MANUAL
MASTER STATION BOARD N-8031SB
1. GENERAL DESCRIPTION
The N-8031SB is a printed circuit board unit for the N-8031MS
Flush-Mount Hands-Free Master Station. You can make the
master station suitable for applications using the N-8031SB in
combination with the operation panel section to be prepared
separately.
3. SPECIFICATIONS
2. DIMENSIONAL DIAGRAM
Use the N-8000 software* to perform settings. Set up the same
items as performed to the N-8031MS since the N-8031SB is
handled as the N-8031MS on the software.
Key and status indicator operations are exactly the same as
those of the N-8031MS.
For settings, functions, and operations, read the descriptions
about the N-8031MS in the N-8000 Series instruction manual*.
* Included in the CD supplied with the N-8000EX/8010EX
Exchange.
4.1. Installation Precautions
• To prevent a malfunction or breakdown due to static electricity,
be sure to use a metal case or metal panel, and screw the board
at the indicated hole, so that the board is electrically conducted
to the case or panel.
4. MOUNTING TO A METAL CASE OR PANEL
• Cover the whole board with a case when installing.
4.2. Speaker and Microphone Installation
• To prevent acoustic feedback, attach the speaker and
microphone closely to the panel and position them at least 16 cm
away from each other's center as shown below.

• Speaker opening ratio should be 36% (Example: ø4 mm x 61
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.
