This unique MantelMount feature will allow the mount to lower 
to the the Memory 1 position whenever the TV is turned on, 
and return home when the TV is turned off. The mount will do 
this automatically without needing to use the Remote Control.
If the TV is plugged into the socket located onboard the MM860 
instead of a wall outlet, MantelMount can monitor the power to 
the TV and determine when it is turned on or off.
If this feature is not desired, simply plug the TV into a wall 
outlet and operate the MM860 with the Remote Control.

MM860 has a rear access hole that accepts threaded fittings for 
standard 1/2" aluminum conduit. A licensed electrician can 
hard wire the mount by splicing into the power cord.
Contact MantelMount for more information.

OPTIONAL:
MM860 includes brackets that make it easier to install horizontal 2x4 bracing inside the 
wall. This is because all the attachment holes in the brackets can be reached for drilling 
and screwing through the opening that is cut for the Lift Housing {30}, see FIG. A.
Notes: If the bracket is near the cutout opening, make sure to orient the attaching 
hardware away from the opening so they do not interfere with the Housing. This 
hardware is attached before the braces are installed into the wall, see FIG. B.
When cutting a center stud, measure 1.5" above and below the template mark before 
the opening is cut out. Plunge cut through the stud at both locations and attach the cut 
ends to the cross braces when they are installed, see FIG. C.
