Read the Operating Instructions carefully and completely before operating the unit. Be sure to keep the Operating Instructions for future reference. All warnings and cautions in the Operating Instructions and on the unit should be strictly followed, as well as the safety suggestions below.
1Water and moisture — Do not use this unit near water, such as near a bathtub, washbowl, swimming pool, or the like.
2Heat — Do not use this unit near heat sources, including heating vents, stoves, or other appliances that generate heat. It also should not be placed in temperatures less than 5°C (41°F) or higher than 35°C (95°F).
3Mounting surface — Place the unit on a flat, even surface.
4Ventilation — The unit should be situated with adequate space around it so that proper heat ventilation is assured. Allow 10 cm (4 in.) clearance from the rear and the top of the unit, and 5 cm (2 in.) from each side.
-Do not place the unit on a bed, rug, or similar surface that may block the ventilation openings.
-Do not install the unit in a bookcase, cabinet, or airtight rack where ventilation may be impeded.
5Objects and liquid entry — Take care that objects or liquids do not get inside the unit through the ventilation openings.
6Carts and stands — When placed or mounted on a stand or cart, the unit
should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause the unit or cart to overturn or fall.
7Wall or ceiling mounting — The unit should not be mounted on a wall or ceiling, unless specified in the Operating Instructions.
1Power sources — Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit.
2Polarization — As a safety feature, some units are equipped with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it is not still inserted easily into the outlet, please call a qualified service technician to service or replace the outlet. To avoid defeating the safety feature of the polarized plug, do not force it into a power outlet.
3AC power cord
-When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull the cord itself.
-Never handle the AC power plug with wet hands, as this could result in fire or shock.
-Power cords should be firmly secured to avoid being severely bent, pinched, or walked upon. Pay particular attention to the cord from the unit to the power socket.
-Avoid overloading AC outlets and extension cords beyond their capacity, as this could result in fire or shock.
4Extension cord — To help prevent electric shock, do not use a polarized AC power plug with an extension cord, receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure of the blades of the plug.
5When not in use — Unplug the AC power cord from the AC power outlet if the unit will not be used for several months or more. When the cord is plugged in, a small amount of current continues to flow to the unit, even when the power is turned off.
1Power lines — When connecting an outdoor antenna, make sure it is located away from power lines.
2Outdoor antenna grounding — Be sure the antenna system is properly grounded to provide protection against unexpected voltage surges or static electricity

Connect the speakers, antennas, and all other external equipment first. Then connect the AC cord at the end.
*1 Be sure to connect the VIDEO (S VIDEO) OUT terminal of a
DVD player directly to a TV set, not through this unit. Otherwise, the picture noise may appear when playing copy protected DVDs.
*2 Input sound through the DIGITAL IN terminals cannot be recorded. When recording the sound from the DVD, CD, MD or LD player, connect the analog AUDIO OUT terminals of the player to the corresponding AUDIO IN terminals of the receiver.
*3 When connecting a monaural video, use a
*4 When connecting an LD player equipped with the
OUT terminal, use an RF demodulator unit. Also connect the analog AUDIO OUT terminals of the LD player to the receiver to play all the sources. For further information, refer to the instructions of the LD player.
