viii. If securing the angle using an angle locking point, align the empty threaded hole
to the preferred angle locking point.
ix. Using a 6mm Allen wrench, tighten all button head screws (B).
5. Review the MKD Series Loudspeaker installation
a. Confirm the loudspeaker is level or plumb depending on the configuration.
b. Confirm the aim angle is as expected.
c. Confirm all hardware is tight.
d. For weather protected applications, confirm all sealants were applied properly.
6. Maintenance of an MKD Series U-Bracket installation
a. WARNING: Not following Maintenance instructions could result in equipment damage,
serious injury or death.
b. Maintenance should only be performed by an experienced technician.
c. As with any professional loudspeaker system, routine maintenance must be conducted in
order to ensure the longevity and safe, consistent performance.
d. Inspect the MKD Series U-Bracket for corrosion and other damage. U-brackets with
visible damage should be replaced and discarded.
e. Inspect hardware securing the u-bracket to the mounting surface for corrosion or
looseness. Tighten loose hardware and consider installing hardware locking methods.
Replace and discard corroded hardware.
f.
Inspect hardware mounting the MKD Series loudspeaker to the u-bracket for corrosion or
looseness. Tighten loose hardware. Replace and discard corroded hardware.
g. For weather protected applications (using MKD-WP Series Loudspeakers), inspect
hardware sealants for cracking or gaps in sealant. Replace damaged sealant with user-
supplied, waterproof, non-hardening, non-locking sealant per the sealant's instructions.
Failure to do so could result in water ingress and damage to the loudspeaker.
h. Clean the MKD Series U-Bracket and MKD Series Loudspeaker with a dry cloth.

mounting and angle lock points. Carefully lower the loudspeaker to the ground.
1. Note, for weather protected applications (using MKD-WP Series
Loudspeakers), apply user-supplied, waterproof, non-hardening, non-
locking thread sealant to the threads of a button head screw (B) per the
thread sealant's instructions. Failure to do so could result in water
ingress and damage to the loudspeaker.
2. Onto a button head screw (B), place a lock washer (C) and a flat washer
(D).
3. Using a 6mm Allen wrench, loosely thread the screw and washers (B, C &
D) through the MKD Series U-Bracket angle lock point and into the
loudspeaker's center threaded mounting hole. Repeat for the opposite
side.
