User manual PIONEER C-21

[. . . ] When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. Output of 4 V or more, adjust level to match the car stereo output level. When the unit does not operate properly, contact your dealer or the nearest authorized PIONEER Service Station. If both L (left) and R (right) channels are connected to the RCA input of this product, output is mixed because this product is a mono amplifier. [. . . ] There is no need to decrease the volume of the head unit and too much output is controlled. To protect the wiring, wrap adhesive tape around it where they lie against metal parts. Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body. Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism. Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. Never replace the fuse with one of greater value or rating than the original fuse. Use of an improper fuse could result in overheating and smoke and could cause damage to the product and injury including burns. Do not ground the speaker wire directly or connect a negative (­) lead wire for several speakers. This unit is for vehicles with a 12-volt battery and negative grounding. If the car stereo is kept on for a long time while the engine is at rest or idling, the battery may go dead. If you decrease the volume of the head unit and set the gain control of the amplifier to the proper position but still the sound cuts out from time to time, contact the nearest authorized PIONEER Service Station. Failure to securely fasten the battery wire to the terminal using the terminal screws could cause the terminal area to overheat and could result in damage and injury including minor burns. The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch. Do not install in: --Places where it could injure the driver or passengers if the vehicle stops suddenly. --Places where it may interfere with the driver, such as on the floor in front of the driver's seat. Make sure that wires are not caught in the sliding mechanism of the seats, resulting in a short-circuit. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Protect all cables and important equipment such as fuel lines, brake lines and electrical wiring from damage. Install tapping screws in such a way that the screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the car, which can result in fire. [. . . ] In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result. Do not install the amplifier on unstable places such as the spare tire board. The best location for installation differs with the car model and installation location. Make temporary connections first and check that the amplifier and the system operate properly. [. . . ]
