Safety precautions 2 WARNING To prevent injury or fire, take the following precautions: • When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 5 mm² (AWG 10) or more to prevent wire deterioration and damage to the wire coating. • To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. • If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. • Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched. 2 CAUTION To prevent damage to the machine, take the following precautions: • Be sure the unit is connected to a 12V DC power supply with a negative ground connection. • Do not open the top or bottom covers of the unit. • Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. • When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction. • To prevent a short circuit when replacing a fuse, first disconnect the wiring harness. 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. 2 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 There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the indicator informs you of the condition.
