3 Precautions Installation location Install this unit where good venti- lation and heat radiation are assured. Do not install where the temperature is abnormally high such as in direct sunlight, or where it is dusty or humid, as this could result in damage to this unit despite proper heat radiation. Do not install this unit where it will create problems for driving the car. Ventilation holes The amplifier has many vacuum tubes, generating much heat. Never close the ventilation holes located on the vacuum tube cover and the bottom plate. If the ampli- fier is installed on a rack or the like, secure ample space for cool- ing and leave the door open. Do not pile up other things on the amplifier and never put articles on it. This can cause malfunctioning. Provide more than 20 cm of space under the upper part of the ceiling plate. The lower part of the bottom plate should also have space equivalent to the height of four legs. Connection with other components When connecting this unit with a CD/DVD player, tuner, or another input unit, turn off the power switches of this unit and all other connected units. Otherwise, a very strong noise may be generat- ed and destroy the speakers. In the worst case, this can cause equipment malfunction. The pin-plug to be inserted in each input terminal of this unit shall be pushed in firmly. If the earth side is inadequately insert- ed, humming and such noise may be generated, resulting in an adverse S/N ratio. Cautions for speaker connections When making speaker system connections, be sure not to cause short-circuiting between ! and @ of the speaker terminals and speaker input terminals of this unit. If signals are applied to the amplifier with its circuit left short- circuited, a large current may be carried in the output circuit and cause malfunctioning. The sound is not generated shortly after the power supply is turned on. This amplifier is equipped with a time muting circuit intended for the separation of the output cir- cuit. For this reason, no sound is generated shortly after the power supply is turned on. If the volume control is moved to a high sound level before this time muting circuit is canceled, a large sound is suddenly generated as a result. We therefore advise initially setting the volume control at a low level. After that, you may move the volume control to your favorite sound level after the initial sound has come out of the speakers. Repair and adjustments When repair and adjustments are needed, please ask the store where you bought the unit or any nearby Luxman Service Center. Cleaning For cleaning, use a piece of soft cloth to wipe the unit such as cleaning cloth available on the market. If the unit has become very dirty, remove the dirt with soft cloth absorbing a small amount of neu- tral detergent, and then wipe the unit with dry cloth. Do not use a solvent like benzine or thinner because such a substance can often damage the exterior. The AC outlet power of this unit is 200W at maximum. The total consumption power for units to be connected shall not exceed 200W. Exceeding this limit can cause fires. (Electric heaters, hair driers, electromagnetic cookers, and other such items should not be connected.) Even though the power consumption is kept within the supply limits, no unit should be connected that may carry a heavy current when the power is ON. Safety cautions Warning This unit is heavy. Be careful when unpacking, carrying, and installation. Safety cautions Caution
