WARNING

When Installing the Speaker

• Referallinstallationworktothedealerfromwhom

the speaker was purchased. Installation requires

extensive technical knowledge and experience.

The speaker may fall off if incorrectly installed,

resulting in possible personal injury.

• Install the speaker only in a location that can

structurallysupport the weightofthespeakerand

the mounting bracket. Doing otherwise may result

in the speaker falling down and causing personal

injuryand/orpropertydamage.

• Wheninstallingthespeakerinthesnowyarea,take

appropriate measures to prevent snow from lying

on the speaker. If the snow lies on the speaker, the

speaker may fall, causing personal injuries.

• Donotuseothermethodsthanspeciedtomount

thebracket.Extremeforceisappliedtothespeaker

andthespeakercouldfalloff,possiblyresultingin

personal injuries.

• Attachthesafetywiretothespeaker.Ifnotattached,

the speaker could fall off, resulting in personal

injury.

• Use nuts and bolts that are appropriate for the

ceiling’sorwall’sstructureandcomposition.Failure

todosomaycausethespeakertofall,resultingin

materialdamageandpossiblepersonalinjury.

• Tighten each nut and bolt securely. Ensure that

the bracket has no loose joints after installation

to prevent accidents that could result in personal

injury.

• Do not mount the speaker in locations exposed

to constant vibration. The mounting bracket can

be damaged by excessive vibration, potentially

causing the speaker to fall, which could result in

personal injury.

• Donotuseanti-rustlubricant.Ifitcontactsresinor

rubberparts,theycoulddeteriorateandcausethe

speaker to fall, possibly resulting in personal injury.

• Avoid installing the speaker in a location close
