MFD-100 Lift Series Installation

It is the responsibility of the dealer installer to ensure this product is properly supported and
meets all local building codes. DO ensure the table structure is capable of holding at least
four times the combined weight of the MFD. This is a minimum requirement. Follow any local
or state codes that apply to your specific area.

The MFD-100 is a furniture-mounted, motorized rotator which “flips” to reveal a hidden microphone or
other small device from inside a table. It is designed for integration into boardroom / classroom tables.
The MFD-100 can be fitted with material from your table so it sits flush with the table top. Weight load
capacity is 3 lbs.

Tools required:

Philips-head Screwdriver
Drill
Wire-management tools (crimper, etc.)
7/64” Allen wrench
Magnetic tape, double-stick tape to attach table surface to rotator

Installation

Figure A

1.) Determine the orientation of rotation for the MFD-100/50 based on the size of the microphone being
used and the size/style of the table in which it will be installed.

2.) Have a professional mill worker cut an 8.25” x 6.25” hole in the conference table based on the
orientation you’ve chosen. The bottom of the hole should be undercut with a route at a 45 degree
angle in the direction of rotation (as shown in Figure C). Be sure to allow enough clearance from
the edge of the table to fit the entire assembly and cabling. The MFD-100 is designed to mount to a
table top no more than ½” thick. If the table top is more than ½” thick, have the mill worker router
out a pocket that is at least 13.28” x 10.75” to house the unit.

3.) Before attaching the unit to the table, unscrew the four screws and remove the top plate from the
unit (as shown in Figure B, below). This is the surface to which the matching tabletop and
microphone/speaker will be affixed.

4.) Determine the microphone location and signal pathway and drill a hole in the top plate large enough
to accommodate all the required cabling. Removing the connector on the microphone cable will
allow for a smaller hole.

For a more seamless appearance, have the mill worker attach a matching piece of wood or veneer
from the table to the top plate. Another wood surface may be attached in the same manner to the
plate in the “down” position as well. ½” is the maximum recommended cover thickness. Use
magnetic tape to hold the decorative table surface to the Top Plate. Do not permanently attach the
wood to the plate until instructed to do so.

REMEMBER: MOST TABLE MICROPHONES NEED TO BE AT TABLE TOP HEIGHT TO WORK CORRECTLY!

5.) Run the necessary wiring from the microphone/speaker through the newly-drilled hole(s), through
the triangular pivot, and out the side of the unit.

6.) Use magnetic tape, double-stick tape, or a similar product to attach the microphone/speaker to the
top plate or wood surface. Depending on the equipment you are using, it might be easier to
connect the wiring before attaching the microphone or speaker. Then, reattach the top plate to the
assembly. If you are adding a matching table surface, make sure there is enough clearance to allow
the device to rotate fully. Once you have verified this, attach the table surface to the plate.

7.) Before installing the MFD in your table, ensure that the top surface is level. If manual level
adjustment is required, unscrew the clamp collar using a 7/64” Allen wrench, adjust the plate until it
is level, and retighten the clamp collar. The location of the clamp collar is shown below.

Figure D

8.) If you have installed wood coverings on the MFD, it is recommended that you wire and test the
rotation before installing it in your table in case any additional modifications are necessary. See the
next section for information about powering the unit and using the included remote control. Make
sure that the wood surfaces are not impeding the rotation before continuing to the next step.

9.) Line up the top plate of the MFD with the cutout in the table. Once it’s aligned properly, attach the
unit to the underside of the table by threading four wood screws through the holes in the side flaps.
Exercise caution when attaching the screws so they don’t protrude through the top of the table. It is
recommended that you work with your mill worker while performing this step to insure a seamless
installation.

Powering the Lift and Remote Control

Attaching the three-button control and powering the lift:

Pin1: ‘Home’ button (BLACK)
Pin 2: ‘Show’ button (RED)
Pin 3: ‘Stop’ button (GREEN)
Pin 4: Ground for control cable
Pin 5: Power ground
Pin 6: Positive Power, 24V DC

When the MFD-100 is receiving power, the red LED light on the inside circuit board will blink.

Using the Remote Control

Use the included hand-held remote control unit to initially setup and test the MFD-100. If operating the
MFD from a control system, remove the hand-held control and integrate momentary contact closure to
pins 1 through 4.

There are three buttons on the remote control unit: “HOME,” “SHOW,” and “STOP.”

HOME: Unit rotates to the stored position and the microphone/speaker is hidden.
SHOW: Unit rotates to the up position and the microphone/speaker is revealed.
STOP: Unit rotation stops.

Programming Positions

Enter Manual Mode: hold STOP for ten seconds – LED on the internal circuit board will flash

Press SHOW to rotate to the show position. Press STOP at the desired position. If you rotate farther
than needed, rotate backwards pressing HOME and STOP at the appropriate position.

To save this position - Press and hold STOP then press and hold SHOW – when LED flashes release
SHOW, then release STOP.

Press HOME to rotate to the home position. Press STOP at the desired position. If you rotate farther
than needed, rotate backwards pressing SHOW and STOP at the appropriate position. To save this
position – Press and hold STOP then press and hold HOME – when LED flashes, release HOME, then
release STOP.

Press and hold STOP – wait for the LED to flash, release. Unit is now programmed.
