Replacing the PC Boards in the Speaker
Read and adhere to all safety warnings in this manual before installing the
speaker.
ELECTROCUTION HAZARD: Electrocution or severe personal injury can occur
when making electrical connections, drilling holes, or lifting equipment. Therefore,
experienced electricians per national and local electrical codes, acting under the
direction of the installation crew safety foreman, should perform the installation.
OBSTRUCTION HAZARD: Property damage, serious injury, or death could occur
if an accumulation of water, snow, dust, etc. resides in the speaker projector or if
any objects are in front of the speaker, severely reducing or preventing operation
of this device. Mount the unit so speaker projector is pointed horizontally
or slightly downward and ensure that the front of the speaker is clear of
obstructions.
SHOCK HAZARD: Property damage, serious injury, or death could occur if the
projector is mishandled during installation or over time. DO NOT rotate the
projector more than 180 degrees, or internal speaker wiring may be damaged.
SHOCK HAZARD: Disconnect ALL power to the speaker before replacing the
PCBs. Failure to do so may result in property damage, serious injury, or death.
To replace the PCBs:
1. Before you begin, remove power from the speaker and open the housing. To open
the housing, use a Phillips® head screwdriver to loosen the two cover screws while
supporting the cover so it does not fall.
2. Loosen the collar nut and rotate the speaker for improved access.
3. Remove existing electronics from the housing.
4. Use paper towels and isopropyl alcohol to remove the white thermal grease from the
housing side walls.
