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.
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. MOUNTING TO A METAL CASE OR PANEL
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.

Metal case or metal 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
16cm away from each other's center as shown below.
16 cm or more
Speaker
•
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.
