X=0.290 ± 0.015 Y=0.300 ± 0.015 Specifications are subject to change without prior notice. EN 61000-3-2 In order to comply with the European Norm 61000-3-2 regarding Electromagnetic compatibility (EMC), it has been included mainly, in the PFC Circuit (Power Filter Correction), on every TV set manufactured from January 2001. On TV set manufactured before the above date (Serial Number 800929 for 70FW-53E or previous), this modification is not required. WARNING Part of this chassis is not isolated from the mains supply. When carrying out any servicing work, ensure that an isolation transformer is connected in the mains supply. To prevent electric shock, do not remove the cover unless you are qualified to do so. Refer servicing work to a qualified engineer. 3 Datasheet pdf - http://www.DataSheet4U.net/ www.DataSheet.co.kr 70FW-53E IMPORTANT SERVICING NOTES Only qualified service personnel are allowed to carry out maintenance and repair of this receiver. SERVICING OF HIGH VOLTAGE SYSTEM AND CRT It is important that the static charge is removed from the high voltag.
