5.0 SAFETY
5.1 Electrical
This product is intended to be operated from a mains power source of 100-120V~ or 200-230V~, 50/60 Hz and a
maximum ac power consumption of 45VA.
WARNING: To avoid risk of electric shock, this equipment must only be connected to a supply mains with
protective earth. Connect the monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor
plug must be inserted into a properly wired three-wire receptacle; if a three-wire receptacle is not available, a
qualified electrician must install one in accordance with the governing electric code.
WARNING: Do not under any circumstances remove grounding conductor from the power plug.
WARNING: The power cable supplied with this equipment provides for this protection. Do not attempt to
defeat this protection by modifying the cable or by using ungrounded adapters or extension cables. The power cord
and plug must be intact and undamaged. To disconnect the equipment from the mains power; unplug the power
cord.
WARNING: Do not connect to an electrical outlet controlled by a wall switch or dimmer.
