[. . . ] Determine and resolve the cause, then replace the fuse with and identical equivalent. Do not install the amplifier on a surface that is not flat or on a surface with a protrusion. Private households in the member states of the EU, in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one). For countries not mentioned above, please contact your local authorities for the correct method of disposal. [. . . ] If output remains low, even when the car stereo volume is turned up, turn controls to lower level. If distortion occurs when the car stereo volume is turned up, turn these controls to higher level. If using only one input plug, set the gain controls for speaker outputs A and B to the same position. For use with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection. , this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down. A cut in sound output may indicate improper setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output. Despite correct volume and gain settings, the unit sound still cuts out periodically. in such cases , please contact the nearest authorized Pioneer Service Station. Gain control of this unit Preout level: 2 V (Standard: 500 mV) 02 English Preout level: 4 V Above illustration shows NORMAL gain setting. About suitable specification of speaker Ensure speakers conform to the following standards, otherwise there is a risk of fire, smoke or damage. Speaker impedance is 2 W to 8 W, or 4 W to 8 W for two-channel and other bridge connections. Do not install or use this amplifier by wiring speakers rated at 2 W (or lower) in parallel to achieve a 1 W (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result. To properly install or use a bridged mode and achieve a 2 W load, wire two 4 W speakers in parallel with Left + and Right * (Diagram A) or use a single 2 W speaker. Two-channel output Speaker output A Speaker output B Three-channel output En 7 Section 03 Connecting the units Connecting the speakers The speaker output mode can be four-channel, three-channel (stereo and mono) or two-channel (stereo or mono).

[. . . ] This is important to prevent wires from being cut by vibration of the car, which can result in fire. Make sure that wires do not get caught in the sliding mechanism of the seats or touch the legs of a person in the vehicle as short-circuit may result. When drilling to install the amplifier, always confirm no parts are behind the panel and protect all cables and important equipment (e. Example of installation on the floor mat or chassis 1 Place the amplifier in the desired installation location. [. . . ]
