BEFORE ENJOYMENT/POWER SUPPLY Follow the instructions below for maximum safety: 1. Use a wall outlet for power supply Be sure to connect the AC line cord to a house-hold wall outlet. Be certain that the outlet voltage matches the elec trical rating of the unit, found on the rear panel name plate. 2. Connecting and removing AC cord Be sure to connect or disconnect the AC line cord only after turning off the power switch to prevent possible shock noise or damage to the speakers. 3. Ventilate the unit well Never block any ventilation holes at the top and bottom of the unit. Be sure also to provide ample ventilation space around the unit. Poor ventilation may result in damage due to excessive heat. CAUTION: To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. SPEAKERS 4. Do not open the cabinet In order to avoid electric shock or damage to the component, never open the cabinet. If a foreign object falls inside the unit by mistake, turn the power off, disconnect the wall plug, and consult a qualified electrician or your dealer. Use speaker systems with impedance ratings of 4-16 ohms, when you hook up 2 sets of speaker systems, be sure to speakers with ratings of 8-16 ohms. Before hooking up your speaker system, check its impedance, which should be in dicated either on the back of the speaker, or in the speaker instruction manual. HOOKING UP SPEAKERS 5. Installation Be sure to place the unit in a level and flat place where it is free from humidity, vibration, high temperature and not exposed to direct sunlight. Be careful not to place the unit in a highly enclosed place such as near a wall or on a bookshelf. A poor ventilation will cause undesirable effects to the unit. 6. Moving the unit When transporting, remove the AC cord from the wall outlet and all other connected cords on the rear panel to prevent wire breakage and short circuits. On the rear panel of the RA-820BX3 are two sets of speaker terminals, "DIRECT" and "REMOTE", to which two speaker systems may be connected. Connect the speaker leads of the right-hand speaker to terminals RIGHT, and the speaker leads of the left-hand speaker to terminals LEFT. Make sure that the "+" speaker lead is connected to the " +" terminal, and the "-" lead to the "-" terminal. Strip 1.0cm (3/8") of the polyvinyl chloride insulation from the end of each speaker lead. Twist the exposed strands tightly, and secure the end with a touch of solder. Note: When only one pair of speakers is used, be sure to connect them to DIRECT terminals, which is "straight-path", so headphone circuit is not connected. If wish to listen to headphone and privately, connect the remote speaker ter minals and use the speaker remote button on front panel to turn speaker off. 7. If the unit gets wet If the unit should get wet, immediately disconnect the AC cord, and consult your dealer or a qualified electrician. 8. Cleaning and maintenance Do not use chemicals such as benzine or thinners on the front panel. Always use a soft, dry cloth to clean the unit.

Playback with AV/AUX Equipment The RA-820BX3 permits connection of one audio-visual or auxiliary components. There are one set of audio inputs for a stereo AV component such as a video disc player or a TV. This system allows high performance operation for optimal sound quality such as digital sound from a Hi-Fi video disc player. Alternatively the inputs can be used for connection with an audio equipment such as another compact disc player. HUM AND NOISE In any high fidelity installation, hum may be caused by the interconnection of a turntable, tuner and amplifier, and speakers as the result of wiring, different grounding or locations of components. If hum is experienced with your unit, disconnect everything but the speakers from the unit. Plug in the turntable and if hum or howling appears, move the turntable away from the speakers as much as possible. Note hum may also be induced by defective cable connec tions or by running the cables too close to strong Ac field. When your unit picks up noise during the reception of broad-casts, causes are mostly due to external objects such as fluorescent lamps and house appliances using motor or thermostat, or others that may induce the noise. Either relocating the unit away from the noise sources or using an improved outdoor antenna may readily solve the problem. In the event you cannot find the cause consult your dealer or a qualified electrician. VOLTAGE SELECTION Not available for U.K., Canada and Scandinavia The unit is a variable voltage equipment that can run on 120V, 220V or 240V power supply. Your unit should already be preset at the proper voltage for use in your area. However, if you move to an area where the power supply voltage is different, consult your dealer.
