When the Unit is in Use
• Do not place objects on the unit as they
can dislodge and cause personal injury
and/or property damage.
• Make sure that the volume control is set

impair hearing.
• Do not operate the unit for an extended
period of time with the sound distorting.
This is an indication of a malfunction or
incorrect gain structure. Turn down the
sound source and check for the source of
distortion. Ignoring this can cause damage
to the speaker system and under some
circumstances can cause heat to generate
and result in a fire.

procedure. If dust is allowed to
accumulate inside the unit over a long
period of time, a fire or damage to the unit
may result.
