Before connecting, turn off the Speaker system, the PC and the audio component to avoid damaging the speaker system. The volume level should not be turned up to the point of distortion. Although this system is magnetically shielded, do not leave recorded tapes, watches, personal credit cards or floppy disks using magnetic coding in front of the system for an extended period of time. Although this system is magnetically shielded, there may be cases that the picture on some TV sets/personal computers may become magnetically distorted. In such a case, turn off the power of the TV set/personal computer once, and after 15 to 30 minutes turn it on again. In the case of a personal computer, take appropriate measures, such as data storage, before turning it off. When there seems to be no improvement, locate the system farther away from the TV set/personal computer. Furthermore, be sure not to place objects in which magnets are attached or used near the TV set/personal computer, such as audio racks, TV stands, toys etc. These may cause magnetic distortion to the picture due to their interaction with the system.
