installation tips:
• It is forbidden to disassemble and modify the product by yourself. Disassembly and modification of the product by
yourself may cause accidents, fire or electric issues.
• This product is recommended for use in an automotive environment with a DC voltage range of 12-14.4V. If this voltage
range is exceeded, the product may malfunction. • It is recommended to install the power supply and RCA at a distance of
at least 20cm apart from the electronic equipment on the vehicle during the installation process to prevent signal
interference. • Before wiring, be sure to disconnect the cable from the negative battery terminal, otherwise it may cause a
short circuit and cause a fire.
• Do not use the screws and nuts in the brake system during installation and grounding, otherwise the brake system will
fail and cause traffic accidents. • When there is no sound, smoke, etc., please stop using it immediately and contact the
Rebec dealer in your city.
• Protect the cable to prevent damage caused by pulling or cutting and short circuit.
• The volume should be adjusted within the zero limit of distortion.
• In order to get a safe, professional and reliable installation, please hand over the product to the modified service shop
authorized by Rebec and let them install it for you. Warning:
The powerful car audio system can create extremely high sound pressure, similar to the level of real live concerts.
Prolonged exposure to excessive sound pressure may cause hearing loss or loss of hearing. In addition, when you listen
to audio equipment at high volume, driving a car may reduce your attention to road traffic and the intensity of listening to
external sounds, such as horns, warning signals, or emergency vehicles. For the sake of the overall situation and your
own safety, it is recommended to listen to music at an appropriate low volume while driving.
