[. . . ] Do not put large or heavy objects on top of the speaker. Do not place magnetic objects such as screwdrivers or iron parts near the tweeter or midrange. Since the speakers use strong magnets, the objects may be attracted, causing injury or damaging the diaphragm. With normal use, wiping with a dry cloth should be sufficient to keep the cabinet clean. [. . . ] There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment, recovery and recycling. Private households in the member states of the EU, in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one). For countries not mentioned above, please contact your local authorities for the correct method of disposal. By doing so you will ensure that your disposed product undergoes the necessary treatment, recovery and recycling and thus prevent potential negative effects on the environment and human health. Sounds played through speaker systems are easily affected in subtle ways by the conditions in the listening space. For best sound, choose a solid floor upon which to place the speakers, and position the speakers as shown below. The level of low sounds can be adjusted by moving the speakers closer to or further from the wall. Adjust the speakers so that they are equidistant from their respective side walls to assure balanced sound. If the room has a lot of reverberation, we recommend hanging heavy fabric on the walls, and/or putting a carpet on the floor to damp the sound. This speaker is a bookshelf-type speaker which will give best performance when placed on a solid, level surface off the floor. Included with this speaker system is a speaker base for better sound, stability and safety. Poor connections can create noise and interruptions in the sound. If the cables' wires happen to be pushed out of the terminals, allowing the wires to come into contact with each other, it places an excessive additional load on the amp. This may cause the amp to stop functioning, and may even damage the amp. When using a set of speakers connected to an amplifier, you won't be able to obtain the normal stereo effect if the polarity (+, ­) of one of the speakers (left or right) is reversed. These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any D3-4-2-2-3_A_En uninsulated parts.
