Warning

	In case of problems, please stop using the device immediately. Continued use may result in personal injury or damage to the product. Please return the product to the authorised Alpine dealer or nearby Alpine service center for repair.
	The product is only suitable for 12V negative-grounded vehicles. Use within other types of vehicles may create a fire or electrical hazard.
	Please contact a professional for wiring and installation. This product requires professional expertise to wire and install. Please contact the dealer from whom you bought the product to install it safely.
	Please do not disassemble or refit. Doing so may result in product damage, fire or electrical hazard.
	Small items like bolts or screws mustbe kept out of the reach of children. If ingested, please seek Immediate medical attention to avoid serious injury.
	Please do NOT use functions that may distract you while driving. Any device function that may influence your attention must be used only when the vehicle is stopped completely. To use these functions, make sure to stop your vehicle in a safe area first. Otherwise, it may result in an accident.
	While driving, you must maintain the volume at a level that allows outside noise to remain audible. It is very dangerous not to hear an emergency vehicle alarm or road warning signal (such as a railway crossing) and may result in an accident. Moreover, excessively loud volume may create permanent hearing damage or hearing loss.

Caution

	Product maintainance Please regularly clean the item with a soft, dry cloth. For tough stains, use only water to dampen the cloth as other solvents may result in dissolution.
	Temperature Before starting the device, please ensure that the temperature inside the vehicle is between +60°C and -20°C.
	Repair In the case of a problem, please do not attempt to repair the product yourself. Please return the product to the authorised Alpine dealer or Alpine service center.
	System matching When PXE-X121-12EV is used with active division mode to assign signals for speakers, please ensure that the crossover frequency is above 1500 Hz to avoid damage to tweeters.
	Installation environment The device cannot be installed at the following locations: • Under direct sunlight or near a source of heat. • With high humidity or near a source of water. • Dusty environments. • Environments with violent vibration.
