IMPORTANT SAFETY INSTRUCTIONS

• Read these instructions and keep a copy for future reference. Strictly follow and heed all instructions and warnings. Install the loudspeaker only as
instructed.

• Do not use or submerge this loudspeaker in or near water or liquids.

• Clean only with a dry cloth. Do not use any aerosol spray, cleaner, disinfectant or fumigant on, near, or into the loudspeaker.

• Do not install the loudspeaker near any heat sources, such as radiators, heat registers, stoves, or other apparatus (including amplifiers).

• Do not use any attachments, accessories, mounts, or brackets that are not specified or approved by QSC, LLC.

• Refer all service to qualified personnel. Service is required if the mounting mechanism or loudspeaker have been damaged in any way, such as liquid
spilled into the loudspeaker; objects falling into it; exposure to rain or moisture; abnormal operation; or being dropped.

• Observe all applicable local codes. Consult a licensed professional engineer when devising an equipment installation to ensure compliance.

Maintenance and Repair

Advanced technology—e.g., the use of modern materials and powerful electronics—requires specially adapted maintenance and repair methods. To
avoid subsequent damage to the equipment, personal injury, and/or creation of additional safety hazards, have all maintenance or repair work on the
equipment performed only by a QSC authorized service station or an authorized QSC international distributor. QSC is not responsible for any injury,
harm, or related damages that arise from any failure of the customer, owner, or user of the equipment to facilitate those repairs.

Prepare Ceiling

Refer to Figure 1.

1. Use the template provided to mark and cut a hole (1) in the
ceiling where the loudspeaker is to be installed. For a frame­construction ceiling, skip to Wire the Loudspeakers.

2. Install two V-rails (2), one on each side of the hole, and
supported by the suspended-ceiling support rails (3).

3. Install the C-ring (3) over the hole, using the V-rails as support.
Make sure the clips on the C-ring are properly fitted over the
V-rail.

4. Use sheet-metal screws (5) to secure the C-ring to the V-rails.
