1. Product Safety Servicing Guidelines

WARNING:

Service should not be attempted by anyone unfamiliar with the necessary

precaution on this receiver. The following are the necessary precaution to be

observed before serving this chassis.

1. Since the power supply circuit of this receiver is directly connected to the AC

power line, an Isolation transformer should be used during any dynamic

service to avoid possible shock hazard.

2. When replacing a chassis in the cabinet, always be certain that all the

protective devices are put back in place, such as:

non-metallic control knobs, insulating cover, shields, isolation

resistor-capacitor network etc.

3. When replacing parts or circuit boards, disconnect the power cord.

4. When replacing a high wattage resistor (oxide metal film resistor) on the

circuit board, keep the resistor (1/2in) away from circuit board.

5. Connection wires must be kept away from components with high voltage or

high temperature.

6. If any fuse in this LCD TV receiver is blown, replace it with the FUSE

specified in the chassis part list.

The lightning flash with arrowhead symbol, within an

equilateral triangle is intended to alert the user to the presence of

uninsulated dangerous voltage within the products enclosure that may be of

sufficient magnitude to constitute a risk of electric shock.

The exclamation point within an equilateral triangle is intended to

alert the user to the presence of important operating and

maintenance (servicing) instructions in the literature accompanying the set.

Many electrical and mechanical parts in the chassis have special

safety-related characteristics. These characteristics are often passed unnoticed

by a visual inspection. When replacement parts are required, be sure the

service technician uses replacement parts specified by us that have the same

characteristics as the original part. Unauthorized substitutions may result in fire,

electric shock and injury to persons or other hazards. This LCD TV product

should be situated away from heat source such as radiation, stoves, or other

product that produce heat.
