Sony ICF-DVD57TV User Manual

If an outdoor antenna or cable system is installed, follow the precautions below.
An outdoor antenna system should not be located in the vicinity of overhead power lines or other 

electric light or power circuits, or where it can come in contact with such power lines or circuits.

WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME CARE SHOULD BE TAKEN 

TO KEEP FROM CONTACTING SUCH POWER LINES OR CIRCUITS AS CONTACT WITH THEM 

IS ALMOST INVARIABLY FATAL.
Be sure the antenna system is grounded so as to provide some protection against voltage surges and 

built-up static charges. Section 810 of the National Electrical Code provides information with respect 

to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an 

antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection 

to grounding electrodes, and requirements for the grounding electrode.

Unplug the appliance from the wall outlet and refer servicing to qualified service personnel under the 

following conditions:

-When the power cord or plug is damage or frayed.

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

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

-The appliance does not appear to operate normally or exhibits a marked change in performance.

 -This indicates a need for service.

-If the appliance does not operate normally when following the operating instructions, adjust only 

 those controls that are specified in the operating instructions. Improper adjustment of other controls   

 may result in damage and will often require extensive work 

 by a qualified technician to restore the appliance to normal operation.

-If the appliance has been subject to excessive shock by being dropped, or the cabinet has been 

 damaged.

Do not attempt to service the appliance yourself as opening or removing covers may expose you to 

dangerous voltage or other hazards.

Refer all servicing to qualified service personnel.

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.

Upon completion of any service or repairs to the appliance, ask the service technician to perform 

routine safety checks (as specified by Sony) to determine that the appliance is in safe operating 

condition.
