resistance value becomes 170 Ω or less.
To N-8000EX Exchange
STANDARD HANDS-FREE MASTER STATION
N-8011MS
This Master Station is designed to connect to the IP Intercom Exchange, and provides hands-free conversation of high sound
quality. With its space-saving design, this Master Station features the same functions as the Standard Master Station.
Using an optional YC-290 Wall Mounting Bracket, this station can be mounted on a wall, or tilted for easy key operation when
used on a desktop.

1.1. Mounting Example
In desktop installations, the front operation panel can be
inclined 16˚ from the desk surface for easier operation by
attaching the YC-290 Wall Mounting Bracket to its bottom
surface.
2.1. Mounting Example
Step 1. Install the YC-290 Wall mounting bracket to the wall.
Notes
• Use appropriate screws for the construction of wall.
• Wooden screws 3.5 x 20 are supplied with the
YC-290.
• No fitting screws for switch box are supplied.
Hang the Wall mounting bracket hook on the station's wall
bracket mounting slot to install.
Push up the Wall mounting bracket in the direction indicated
by the arrow.

The types of cables are to be determined according to the
following conditions.
• Twisted pair wires (such as those used for electronic pushbutton telephone) are to be used for wiring between the
Exchange and the stations in principle.
• The number of cables pairs laid should be determined
considering the possibility of future expansion of the
system.
• Outdoor wires should be used where wiring passes through
inaccessible areas such as ceilings or under floors where
the maintenance is not performed. Indoor wires may also be
used, however, in case where there is no risk of
deterioration due to exposure to heat, etc.
Note
Specifications related to each junction are as follows.
Step 2. Hang the station on the Wall mounting bracket hook
to install.
Push down the station main body in the direction
indicated by the arrow.

Step 1. Cut off two-cable ends in equal length, and insert
them securely to a cover section (transparent side)
of the mini-clamp connector.

Step 2. With a pair of pliers, lightly pinch the mini-clamp
cover and, after ensuring that the cable is securely
inserted, firmly squeeze on the cover.
Note
Squeeze on the mini-clamp cover until it is correctly
locked.
Step 3. Insert the wired connector (plug) into the exchange's
connector (socket) until it locks into place.
