[. . . ] The color will change from green to red when the voltage going out to the speaker terminal or the pin Jack is too high. THERMAL lights up in green during normal operation. The color will change from green to red when the temperature rises to an unsafe level. The color will return to green when the temperature returns to normal. OVER CURRENT lights up in green during normal operation. The color will change from green to red when receiving a powerful signal. 4 LEVEL adjustment control (FRONT/REAR) The input level can be adjusted with this control when using source equipment made by other manufacturers. Turn it to MAX when the output level of the car audio seems low. 5 TEST TONE button To check the system's status , activate the built-in transmitter then press the TEST TONE button. If the tone is heard, the unit is functioning normally. Mount the unit either inside the trunk or under a seat. If you use small capacity speakers, they may be damaged. Do not connect the # terminal of the speaker system to the car chassis, and do not connect the # terminal of the right speaker with that of the left speaker. Install the input and output cords away from the power supply lead as running them close together can generate some interference noise. Therefore, it may not perform to its full potential if used with the speaker cords supplied with the car. If your car is equipped with a computer system for navigation or some other purpose, do not remove the ground wire from the car battery. If you disconnect the wire, the computer memory may be erased. To avoid short circuits when making connections, disconnect the +12 V power supply lead until all the other leads have been connected. If the fuse blows again after replacement, there may be an internal malfunction. When replacing the fuse, be sure to use one matching the amperage stated above the fuse holder. Never use a fuse with an amperage rating exceeding the one supplied with the unit as this could damage the unit. Note When you tighten the screw, be careful not to apply too much torque* as doing so may damage the screw. [. . . ] Right speaker Haut-parleur droit Left speaker Haut-parleur gauche * If you have the factory original or some other car audio without a remote output on the amplifier, connect the remote input terminal (REMOTE) to the accessory power supply. purple Mauve Notes on the power supply · Connect the +12 V power supply lead only after all the other leads have been connected. Be sure to connect the ground lead of the unit securely to a metal surface of the car. A loose connection may cause the amplifier to malfunction. [. . . ]
