1. Precautions

Samsung Electronics 1-1

1. Warning: Prior to repair, disconnect the

power cord from the circuit breaker.

2. Use proper parts: Use only exact

replacement parts. (Also, we recommend

replacing parts rather than repairing them.)

3. Use the proper tools: Use the proper tools

and test equipment, and know how to use

equipment may cause problems later-

intermittent contact, for example.

4. Power Cord: Prior to repair, check the

power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid

tapping into a power cord. This practice

may result in malfunction or fire.

6. After completing repairs and reassembly,

check the insulation resistance, Procedure:

Prior to applying power, measure the

resistance between the power cord and the

ground terminal. The resistance must be

greater than 30 megohms.

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions

are satisfactory. Relocate the unit if

necessary.

9. Keep children away from the unit while it is

being repaired.

10. Be sure to clean the unit and its surrounding

area.
