Page 8: Precautions
High voltages and lasers inside this product are dangerous. This product should only be serviced by a factory trained service technician. 2) Use only Samsung replacement parts. There are no user serviceable parts inside the product. Do not make any unauthorized changes or additions to the product as these could cause the product to malfunctions and create an electric shocks or fire hazards.
Page 9: Caution For Safety
Exposed cables could cause an electric shock. Replace the damaged power cable immediately, do not reuse or repair the damaged cable. Some chemicals can attack the coating on the power cable, weakening the cover or exposing cables causing fire and shock risks. Copyright© 1995-2013 SAMSUNG. All rights reserved.
Page 10 Take care not to cut or damage the power cable or plugs when moving the machine. 9) Use caution during thunder or lightning storms. Samsung recommends that this machine be disconnected from the power source when such weather conditions are expected. Do not touch the machine or the power cord if it is still connected to the wall socket in these weather conditions.
Page 11: Handling Precautions
1.2.4. Assembly and Disassembly precautions 1) Replace parts carefully and always use Samsung parts. Take care to note the exact location of parts and also cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly. Please carry out the following procedures before dismantling the product or replacing any parts.
