[. . . ] Operating environment temperature and humidity: +5 °C to +35 °C (+41 °F to +95 °F); less than 85 %RH (cooling vents not blocked) Do not install this unit in a poorly ventilated area, or in locations exposed to high humidity or direct sunlight (or strong artificial light) D3-4-2-1-7c*_A1_En Before plugging in for the first time, read the following section carefully. The voltage of the available power supply differs according to country or region. Be sure that the power supply voltage of the area where this unit will be used meets the required voltage (e. If the AC plug of this unit does not match the AC outlet you want to use, the plug must be removed and appropriate one fitted. [. . . ] Batteries with the same shape may have different voltages. Do not use different batteries together. ⷠWhen disposing of used batteries, please comply with governmental regulations or environmental public institution's rules that apply in your country or area. ⷠWARNING Do not use or store batteries in direct sunlight or other excessively hot place, such as inside a car or near a heater. This can cause batteries to leak, overheat, explode or catch fire. It can also reduce the life or performance of batteries. Make sure not to bend the cables over the top of this unit (as shown in the illustration). If this happens, the magnetic field produced by the transformers in this unit may cause a humming noise from the speakers. The number and kind of connections depends on the kind of component you're connecting. Follow the steps below to connect a CD player, tape recorder, turntable or other audio component. Before making or changing any connections, switch off the power and disconnect the power cord from the AC outlet. Make sure to complete all connections before connecting to an AC outlet. ⷠConnect the AC power cord to the AC IN inlet on the rear panel of the amplifier, then plug into an AC outlet. 4 DIRECT Press to switch the Direct listening feature on or off (page 12). 8 PHONES jack Use to connect headphones (when connected, there is no sound output from the speakers). 1 When the unit is in the standby mode, if the power is turned off by pressing the main unit's POWER button, the power will not turn on if the button is pressed again. To turn on the power in this case, press either the remote control unit's AMP button or the DIRECT button on the main unit for about five seconds. Keep in mind the following when using the remote control: · Make sure that there are no obstacles between the remote and the remote sensor on the unit. ⷠThe remote has a range of about 7 m at an angle of about 30º from the remote sensor. ⷠRemote operation may become unreliable if strong sunlight or fluorescent light is shining on the unit's remote sensor. Remote controllers for different devices can interfere with each other. Avoid using remotes for other equipment located close to this unit. [. . . ] Operating other Pioneer components with this unit's sensor Many Pioneer components have SR CONTROL jacks which can be used to link components together so that you can use just the remote sensor of one component. When you use a remote control, the control signal is passed along the chain to the appropriate component. ⷠNote that if you use this feature, make sure that you also have at least one set of analog audio jacks connected to another component for grounding purposes. 1 Connect the CONTROL OUT jack of this amplifier to the CONTROL IN jack of another Pioneer component.
