• Secure the wiring with cable clamps or adhesive |
tape. To protect the wiring, wrap adhesive tape |
around it where they lie against metal parts. |

• Do not shorten any wires. Otherwise the protec- |
tion circuit may fail to work when it should. |
• Never feed power to other equipment by cutting |
the insulation of the power supply wire to tap |
from the wire. The current capacity of the wire |
will be exceeded, causing overheating. |
• Never replace the fuse with one of greater value |
or rating than the original fuse. Use of an improp- |
er fuse could result in overheating and smoke and |
could cause damage to the product and injury |
including burns. |

voltage. |
• If the car stereo is kept on for a long time while |
the engine is at rest or idling, the battery may go |
dead. Turn the car stereo off when the engine is at |
rest or idling. |
• If the system remote control wire of the amplifier |
is connected to the power terminal through the |
ignition switch (12 V DC), the amplifier will |
always be on when the ignition is on— regardless |
of whether the car stereo is on or off. Because of |
this, the battery could go dead if the engine is at |

damaged. |
