[. . . ] To prevent fire or shock hazard, do not expose the unit to rain or moisture. Do not install the appliance in a confined space, such as a bookcase or built-in cabinet. 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. Before operating the receiver, check that the operating voltage is identical with your local power supply. [. . . ] Each time you press SHIFT, the letter "A, " "B" or "C" appears in the display. While MEMORY is displayed, press the number you want to use (0 to 9). Repeat Steps 2 to 5 to preset other stations. Preset a new station on the number you want to change. If the AC power cord is disconnected for about one week, the preset stations will be cleared from the receiver's memory, and you will have to preset the stations again. You can take advantage of surround sound simply by selecting one of the pre-programed "sound fields" that your receiver provides. You can enjoy the sound of a movie theater or concert hall in your own home. You can even customize a sound field by adjusting its parameters. When a sound field in this type is selected, the receiver adds the reverberation to the normal 2-channel stereo sound. You can apply these sound fields when playing a CD or watching TV programs to obtain the surround effects of concert hall or a jazz club. To enjoy Dolby Pro Logic Surround sound fully, do the procedure on "Dolby Surround Setup" starting from page 10 to select the center mode and adjust the speaker volume. Sound field are classified into three types. The CINEMA type sound fields are designed for enjoying movies recorded on videos or laser discs. Four sound fields are included in the CINEMA type and they are grouped into two types. PRO LOGIC sound field can be used to reproduce plain surround sound. When you select the PRO LOGIC sound field, the receiver obtains full surround sound by using Dolby Pro Logic to decode Dolby Surround encoded software. The surround sound is reproduced in the exact way that the sound engineer of the software intended. Other sound fields in the CINEMA type are designed to add more reverberation effects by incorporating Digital Cinema Sound technology. When you select these sound fields, the receiver adds the reflection and reverberation effects that are typical in movie theaters to the decoded Dolby Pro Logic Surround sound. You can enjoy the sound that you would experience in the movie theater. Virtual mode allows you to enjoy the surround sound environment using a minimum of two front speakers to create non-existent `virtual' speakers. The listener would be able to feel the surround effects using only front speakers. [. . . ] By adjusting the delay time of the rear speakers, you can obtain the feeling of presence. Make the delay time longer when you have placed the rear speakers in a small room or close to your listening position, and make it shorter when you have placed them in a large room or apart from your listening position. Select NORMAL mode if you have front and rear speakers and a small center speaker. Since a small speaker cannot produce enough bass, the bass sound of the center channel is output from the front speakers. [. . . ]
