■WALL MOUNTING
Attach the upper mounting adaptors to the upper side of
the unit, and pull out the lower mounting adaptors from the
lower side. Fasten a M4 screw through the mounting hole
(4.5 mm dia.) of each adaptor. (torque 1.4 N∙m)
To remove the upper mounting adaptor from the unit, pull
it out while squeezing the latches as shown in the figure
below.
