Use the plug that is provided with the display. If you are unable to insert the plug into the
outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the grounding-type plug.
For international installation with a power source of 88-264 VAC, use a minimum 0.75 mm2
PVC sheathed three-core flexible cord, type H05VV-F3G, with a green/yellow protective
earthing conductor electrically connected to the protective earthing terminal within the
equipment and connected to the protective earthing contact of the plug. The cable set should
have safety approvals for the international installation and be marked HAR.
For plugged equipment, the socket-outlet shall be installed near the equipment and shall be
easily accessible.
Operate the display from the type of power source indicated on the marking label. If you are
unsure of the type of power available, consult your dealer or local power company.
When your display is switched off, be aware that it still carries full line voltage. To completely
remove all voltages from the display, you must unplug the power cable from the wall outlet.
Operating and Maintenance Guidelines
Keep the area around the display free from static electricity and magnetic fields. Before you
touch the display, discharge static electricity on your body by touching a metallic surface.
