Page 4 G. Interference and Attenuation A phone may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from unsuppressed engines or electric motors may cause problems. H. Electrostatic Sensitive Devices ATTENTION Boards, which contain Electrostatic Sensitive Device (ESD), are indicated by the sign. Following information is ESD handling: • Service personnel should ground themselves by using a wrist strap when exchange system boards. • When repairs are made to a system board, they should spread the floor with anti‐static mat which is also grounded. • Use a suitable, grounded soldering iron. • Keep sensitive parts in these protective packages until these are used. • When returning system boards or parts like EEPROM to the factory, use the protective package as described described. ‐ 5 ‐ LGE Internal Use Only - 4 - Copyright © 2014 LG Electronics.
