User manual PIONEER PRS-D2100T

[. . . ] When the unit does not operate properly, contact your dealer or the nearest authorized PIONEER Service Station. Always use the special red battery and ground wire [RD-223], which is sold separately. Do not touch the amplifier with wet hands. Otherwise you may get an electric shock. [. . . ] for details , see the "Setting the Unit" section. Fuse (30 A) Special red battery wire [RD-223] (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. Always use the special red battery and ground wire [RD-223], which is sold separately. Fix the wires securely with the terminal screws. Expose the end of the speaker wires using nippers or a cutter by about 10 mm and twist. Connect the car stereo speaker output wires to the amplifier using the supplied speaker input wire with RCA pin cord. Pass the battery wire from the engine compartment to the interior of the vehicle. After making all other connections to the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. 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. Turn the car stereo off when the engine is at rest or idling. If the system remote control wire of the amplifier is connected to the power terminal through the ignition switch (12 V DC), the amplifier will always be on when the ignition is on-- regardless of whether the car stereo is on or off. Because of this, the battery could go dead if the engine is at rest or idling. Speakers to be connected to the amplifier should conform with the standards listed below. If they do not conform, they may catch fire, emit smoke or become damaged. The speaker impedance must be 2 to 8 ohms for stereo connection, and 4 to 8 ohms for monaural and other bridge connection. Install and route the separately sold battery wire as far away as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner. Cords for this product and those for other products may be different colors even if they have the same function. When connecting this product to another product, refer to the supplied manuals of both products and connect cords that have the same function. 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. [. . . ] Specifications and the design are subject to possible modification without notice due to improvements. The average current drawn is nearly the maximum current drawn by this unit when an audio signal is input. Use this value when working out total current drawn by multiple power amplifiers. To ensure proper heat dissipation of the amplifier, be sure of the following during installation. [. . . ]
