3 Precautions Installation place This unit shall be installed in a well- ventilated and effectively heat- released place. Especially, installation of this unit where direct sunlight is present, where the temperature rises exces- sively high such as close to a heater, or where it is humid or dusty may cause a malfunction even if heat is efficiently released. Therefore, do not install this unit in such places. Ventilation holes If the amplifier 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. Failure to observe this may cause a malfunction. Note: For heat dispersal, do not install this equipment in a confined space such as a book case or similar unit. Precautions in connecting with other components When connecting this unit to input devices such as a CD/DVD player, a tuner, and a recorder, be sure to turn off the power of this unit and all other connected devices. Failure to observe this may generate a strong noise resulting in speaker damage or cause a malfunction. The pin-plug to be inserted in each input terminal of this unit shall be pushed in firmly. If the grounding ter- minal is inadequately connected, nois- es including hum may be generated, resulting in an adverse S/N ratio. Cautions in connecting speakers When making speaker system con- nections, exercise extra care not to short-circuit between !and @of the speaker terminals and speaker input terminals of this unit. If a large signal is applied to the amplifier with its cir- cuit left short-circuited, a large current may be passed through the output cir- cuit and cause a malfunction. The sound is not generated shortly after the power supply is turned on. This amplifier is equipped with a time muting circuit in order to separate the output circuit. Therefore, no sound is generated shortly after the power sup- ply is turned on. If the volume control is moved to a high sound level before the time mut- ing circuit is canceled, a large sound is suddenly generated. Please be advised that the volume control shall be set to a low level at first and adjust- ed after sound comes out of the speakers. Protection circuit This product is equipped with the pro- tection circuit that is activated upon detection of overcurrent, abnormally high temperature, and DC drift to pro- tect the amplifier and speakers. When the protection circuit is activated, the output to the speaker terminal is shut off and the standby indicator blinks to show that this unit is in the muting state. If the protection circuit is fre- quently activated after a lapse of a certain time and turning on the power again, please consult your dealer. Batteries Caution: Batteries used for remote controller shall not be exposed to excessive heat such as sunshine, fire or the like. Repair and adjustment When repairs or adjustments are needed, please ask the dealer where you bought the unit. 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 remarkably dirty, remove the dirt with soft cloth absorbing a small amount of neutral detergent, and then wipe the unit with dry cloth. Do not use a solvent like benzine or thinner because such a substance can dam- age the exterior. * Note Wall * * *
