Lightning: For added protection for the unit during a
lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and

as opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to
qualified service personnel.
Damage Requiring Service: Unplug the unit from the wall
outlet and refer servicing to qualified personnel under the
following conditions:
• When the power-supply cord or plug is damaged,
• If liquid has been spilled, or objects have fallen into
the unit,
• If the unit has been exposed to rain or water,
• If the unit does not operate normally by following the
operating instructions,
• If the unit has been dropped or damaged in any way.
• When the unit exhibits a distinct change in
performance– this indicates a need for service.
Replacement Parts: When replacement parts are
required, be sure the service technician uses replacement
parts specified by the manufacturer or which have the
same characteristics as the original parts. Unauthorized
substitutions may result in fire, electric shock, or other
hazards.
Heat: The unit should be situated away from heat sources
such as radiators, heat registers, stoves, or other units
(including amplifiers) that produce heat.
