As well as enjoying normal stereo reproduction with both the left and right front speakers connected, a center speaker and rear speakers can also be connected to the main unit in order to enjoy playback with a feeling of presence using the Dolby Pro-Logic Systems. The illustration below shows where to place the speakers when enjoying sound with Dolby Pro-Logic systems. The listening position at which the effect is the greatest is a position slightly to the rear of a center position of five-speaker systems. However the position should be adjusted to your personal preference, because the effect varies to some degree depending upon the type of music and the music source.

The battery life is about one year. Although the battery life varies depending on how often the device is used, the batteries should be replaced about once every year on the average. The batteries should be replaced if commands from the remote control transmitter do not operate the unit even when transmitter is held close to the front panel. Never subject batteries to excessive heat or flame; do not attempt to disassemble them; and be sure they are not short-circuited. If the remote control is not to be used for a long period of time, remove the batteries and store them in a cool, dark place.
If a battery leaks, remove all batteries and dispose of them properly. Thoroughly clean the battery compartment before inserting new batteries. If the electrolyte comes into contact with skin or clothes, flush with water immediately. Keep batteries out of reach of children.
Do not use rechargeable (nickel-cadmium) type batteries.
Do not attempt to recharge alkaline or carbon batteries.
