[. . . ] 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. By doing so you will ensure that your disposed product undergoes the necessary treatment, recovery and recycling and thus prevent potential negative effects on the environment and human health.

When you turn down the volume of the head unit the sound output will be restored. If sound output is cut, the gain control of this unit may be improperly set. To ensure continuous sound output at increased volume of the head unit, set the gain control of the amplifier to a proper position according to the preout maximum output level of the head unit. There is no need to decrease the volume of the head unit and too much output is controlled. Relationship between the gain of the amplifier and the output power of the head unit Power Normal gain Equal power Power Maximum gain If you raise the gain of the amplifier to an improper level, only distortion is increased and the power increases only slightly. The above illustration shows the gain set to NORMAL. With high output the signal waveform is distorted, if you raise the gain of the amplifier the power changes only slightly. 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. To protect the wiring, wrap adhesive tape around it where they lie against metal parts. Grommet Fuse (40 A) × 2 Special red battery wire [RD-228] (sold separately) After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Ground wire (black) [RD-228] (sold separately) Connect to metal body or chassis. Car stereo with RCA output jacks Jack for the bass boost remote control Connect this jack and the bass boost remote control with the bass boost remote control wire. 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 connect a cord having an exposed core wire to the power terminals of this amplifier (Power terminal, GND terminal, System remote control terminal). Since the wire will become loose over time, it must be periodically inspected and tightened as necessary. Do not solder or bind the ends of the twisted wires. Fasten while making sure to not to clamp the insulating sheath of the wire. Use the supplied hexagonal wrench to tighten and loosen the terminal screw of the amplifier. securely fasten the wire with the terminal screw. [. . . ] 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. DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. [. . . ]
