Keep the following in mind when placing each adaptor.AC outletsFor best results, we recommend connecting the adaptors directly to a walloutlet. Avoid connecting high power-consuming appliances to the same walloutlet. Additionally, connecting an adaptor to a uninterruptable power supply(UPS) or backup power supply device is not recommended.While connecting the adaptors to a wall outlet is recommended, keep thefollowing in mind if you must connect an adaptor to a power strip:• Make sure the power strip does not have a noise filter or a surgeprotector, as these features may interfere with the performance ofyour adaptors.• Do not connect the adaptor to a power strip that receives power fromanother power strip.• Use a power strip with an AC cord that is as short as possible.Electrical interferenceCertain electrical devices emit electrical noise. If this noise is passed on tothe electrical wiring in your home, it may interfere with the performance,speed, and reliability of your adaptors. For best results, we recommendconnecting an electrical noise filter to noise emitting appliances.The following appliances are more likely to produce noise:• Battery chargers (including cell phone chargers)• AC adaptors (including AC adaptors for modems, routers, notebookcomputers, etc.)• Hair dryers• Vacuum cleaners• Lights or lamps which have a dimmer switch or a touch-sensitiveon/off feature• Power drillsAdditionally, this product may interfere with the following appliances:• Short wave radios• Lights or lamps which have a touch-sensitive on/off feature• Wireless devices (including wireless mice, etc.)
