Information on Disposal of Old Electrical and Electronic Equipment (applicable for EU countries that have adopted separate waste collection systems) Products with the symbol (crossed-out wheeled bin) cannot be disposed as household waste. Old electrical and electronic equipment should be recycled at a facility capable of handling these items and their waste byproducts. Contact your local authority for details in locating a recycle facility nearest to you. Proper recycling and waste disposal will help conserve resources whilst preventing detrimental effects on our health and the environment. This Product is not installed by the manufacturer of a vehicle on the production line, nor by the professional importer of a vehicle into an EU Member State. Cleaning the unit If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. CAUTION Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off. To prevent battery rise When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. Use it after starting the engine. Protection function The protection function is activated in the following situations: 4Ω This unit is equipped with a protection function for protecting this unit and your speakers4Ωfrom various accidents or problems that can occur. When the protection function is triggered, the PROTECTION indicator lights and the amplifier4Ωstops 4Ω operating. 4Ω 4Ω • When a speaker wire may be short-circuited. • When a speaker output contacts gro4uΩnd. • When the unit malfunctions and a DC signal is sent to the speaker output. 7 Wiring • Take the battery wire for this unit directly from the battery. If it's connected to the vehicle's wiring harness, it can cause blown fuses etc. • If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire. • Do not allow the wire to directly contact the edge of the iron plate by using Grommets. • Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery's negative · terminal. Do not turn the power on if the ground wire is not connected. • Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit's fuse capacity or somewhat larger. • For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit's fuse capacity. (Use a power wiring cord with the range of 14 mm² (AWG 6) to 21 mm² (AWG 4). • When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. 7 Speaker Selection • The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage. • The impedance of the speakers that are going to be connected should be 2Ω or greater (for stereo connections), or 4Ω or greater (for bridged connections). Wh4eΩn more than one set of speakers are going to be used, calculate the comb4inΩed 4Ω impedance of the4Ωspeakers and then connect suitable speakers to the amplifier. 8Ω 2Ω 4Ω 4Ω 8Ω 4Ω 4Ω 2Ω Combined impedance English
