Safety Precautions
The symbols shown at left are internationally accepted symbols that
warn of potential hazards with electrical products. The lightning flash
with arrowpoint in an equilateral triangle means that there are dan-
gerous voltages present within the unit. The exclamation point in an
equilateral triangle indicates that it is necessary for the user to refer to
the owner's manual.
These symbols warn that there are no user serviceable parts inside the unit. Do not open the unit. Do not
attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any
reason will void the manufacturer's warranty. Do not get the J-12 wet. If liquid is spilled on the unit, shut it
off immediately and take it to a dealer for service. Disconnect the equipment during storms to prevent dam-
age.
