Before going through the checklist below, refer to the connection and operating procedures. Location and Function of Controls Cause/Solution The fuse is blown. [. . . ] In this case, relocate the amplifier away from the car audio unit or antenna. If no power is being supplied to the car audio unit, check the connections. This power amplifier employs a protection circuit* to protect the transistors and speakers if the amplifier malfunctions. Do not attempt to test the protection circuits by covering the heat sink or connecting improper loads. Do not use the unit on a weak battery as its optimum performance depends on a good power supply. For safety reasons, keep your car audio unit volume moderate so that you can still hear sounds outside your car. Warning 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. * Protection circuit This amplifier is provided with a protection circuit that operates in the following cases: -- when the unit is overheated -- when a DC current is generated -- when the speaker terminals are short-circuited. The color of the POWER/PROTECTOR indicator will change from green to red, and the unit will shut down. If this happens, turn off the connected equipment, take out the cassette tape or disc, and determine the cause of the malfunction. If the amplifier has overheated, wait until the unit cools down before use. · 12 V DC. Precauciones · 2 8 (4 Esta , para ). 8 unidad está diseñada utilizarse sólo con cc · 12 V negativo a masa.

[. . . ] Une connexion lâche risque de provoquer un problème de fonctionnement de l'amplificateur. Veillez à raccorder le fil de commande à distance de l'autoradio à la borne de commande à distance. Si vous utilisez un autoradio dont l'amplificateur ne comporte pas de sortie de commande à distance, raccordez la borne d'entrée de commande à distance (REMOTE) à la prise d'alimentation accessoires. Utilisez un câble d'alimentation doté d'un fusible (50 A). Note In this system, the volume of the subwoofer will be controlled by the car audio unit fader control.
