– When the power cord or plug is damaged or frayed.

– If liquid has been spilled or objects have fallen into the appliance.

– If the appliance has been exposed to rain or water.

dangerous voltage or

other hazards. Refer all servicing to qualified service personnel.

Replacement parts

When replacement parts are required, be sure the service technician has used replacement parts specified by Sony that have the same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock, or other hazards.
