Precautions On safety Should any solid object or liquid fall into the cabinet, unplug the receiver and have it checked by qualified personnel before operating it any further. On power sources  Before operating the receiver, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate on the back of the receiver.  If you are not going to use the receiver for a long time, be sure to disconnect the receiver from the wall outlet. To disconnect the AC power cord (mains lead), grasp the plug itself; never pull the cord.  The AC power cord (mains lead) must be changed only at a qualified service shop. On heat buildup Although the receiver heats up during operation, this is not a malfunction. If you continuously use this receiver at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet. 50GB On placement  Place the receiver in a location with adequate ventilation to prevent heat buildup and prolong the life of the receiver.  Do not place the receiver near heat sources, or in a place subject to direct sunlight, excessive dust, or mechanical shock.  Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions.  Do not place the receiver near device such as a TV, VCR, or tape deck. (If the receiver is being used in combination with a TV, VCR, or tape deck, and is placed too close to that device, noise may result, and picture quality may suffer. This is especially likely when using an indoor antenna (aerial).)  Use caution when placing the receiver on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result. On operation Before connecting other device, be sure to turn off and unplug the receiver. On cleaning Clean the cabinet, panel, and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as alcohol or benzine.
