Taking time to read these operating instructions carefully before use will acquaint you fully with all its features and help ensure optimum performance. In order to simplify the explanation illustrations may sometimes differ from the originals. Do not remove the case and bottom panel Any inspections or adjustments inside the unit may lead to malfunctions and electric shocks. Do not touch any of the inside parts. RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER(OR BACK) NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. Do not block the ventilation holes Do not block the ventilation holes on the top of the unit by placing records or other objects over them. This will increase the inside temperature may lead to a failure or malfunction. The lighting flash with arrowhead symbol, within an equilateral, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. * The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature * accompanying the appliance. WARMING: To prevent fire or shock hazard, do not expose this appliance to rain or moisture * * Installation precautions Do not install the unit in any of the following locations since this may result in deterioration in performance of malfunction: Locations exposed to direct sunlight or near objects radiating heat such as heating appliances. Locations exposed to moisture or humidity. Locations with poor ventilation exposed to dust and dirt. Locations which are unstable and not perfectly flat or which are susceptible to vibration. Do not wipe with thinners Wipe the panels and case from time to time with a soft cloth. Using any kind of thinner, alcohol or volatile liquid will mar the surface, cause blotching on the exterior and erase the markings and should therefore be avoided. Do not use insecticide sprays in the vicinity. Power plug When disconnecting the power cord from the power outlet, always take hold of the plug, and not the wire, and pull free. Never connect or disconnect the power plug with wet hands since you may receive an electric shock. Remember to disconnect the power plug from the power outlet when you do not intend to use the unit for a prolonged period of time. 1 CONNECTIONS FOR INTEGRATED STEREO AMPLIFIER Refer to page 4 the connection diagram as you read the following. Connection precautions When connecting, either disconnect the power plug from the power outlet or turn off the unit's power using the POWER switch. Check the left and right channels and connect properly (Left to L and Right to R). Insert the plugs securely. Improper connection can lead to the generation of noise.

They also come in handy for connecting an AV (audio/video) selector unit. Use pin-plug cords to connect the REC terminals to the INPUT terminals on the selected component and also to connect the PLAY terminals to its OUTPUT terminals. R R AUDIO AMI CD/AUX terminals These terminals have an electrical performance which is equivalent to that of the CD terminals and the TUNER terminals which means that they can be used as the audio output terminals for a video disc player or TV tuner.

A B 2 CONNECTIONS Speaker systems Connect the speaker systems to the SPEAKERS terminals on the rear panel of the unit with the speaker cords. When viewed from the front (the listening position), the speaker mounted on the left should be connected to the L terminals, and the speaker mounted on the right should be connected to the R terminals. Be sure to connect the polarities of the speaker systems and the SPEAKER terminals correctly (+ to +, - to -). If the polarity of one of the speaker systems is connected improperly, sound in the central area between the speakers will appear to be missing, and the position of the instruments will not be clear, resulting in a loss of stereo directionality; so take care when connecting. * When connecting, do not allow the conductor of the speaker cords to be exposed from the terminals and come into contact with other terminals.
