Maintaining the Speaker
UNAUTHORIZED REPAIR/SERVICING — Unauthorized
repair/servicing of the speaker may result in degradation of
performance and/or property damage, serious injury, or death
to you or others. If a malfunctioning unit is encountered, do not
attempt any field repair/retrofit of parts.
EXPLOSION HAZARD — Property damage, serious injury or
death could occur if this product's machined sealing surfaces
are damaged. To maintain the effectiveness of the explosion-
proof enclosure, use caution to avoid damaging the machined
surfaces.
Periodically check this device to verify that there are no foreign
substances in, or in front of, the speaker which will reduce its
effectiveness.
Testing should be periodically performed. Refer to NFPA 72G, local
Fire Codes and the authority having jurisdiction for information.
If a volume adjustment or other repair is needed, be sure to refer to
the "Safety Message For Maintenance Personnel" on page 18 before
proceeding.
