Under-furniture mounting
The unit can be mounted under a horizontal surface using an 
optional MBU 125 under-desk mounting kit (part #70-077-01). 
Mount the unit under a desk or table as follows:

transmitter or receiver with the four machine screws 
provided in the mounting kit (gure 2-3).
2.  Hold the transmitter or receiver with attached brackets 
against the underside of the desk or other furniture. Mark 
the location of holes for screws on the desk.

.  Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot 
holes in the table or desk at the marked screw locations 
from the underside or inside (the concealed side) of the 
furniture, where the transmitter or receiver will be located.
4.  Insert the four wood screws into the pilot holes. Fasten 
each screw into the installation surface until just less than 
1/4" of the screw head protrudes.
5.  Align the installed screws with the slots in the mounting 
brackets, and place the transmitter or receiver against the 
surface, with the screws through the bracket slots.
6.  Slide the transmitter or receiver slightly forward or back, 
then tighten all four screws to fasten it in place.
