[. . . ] Don't pass the yellow lead through a hole into the engine compartment to connect to the battery. This will damage the lead insulation and cause a very dangerous short. If you do, the protection circuit may fail to work when it should. Never feed power to other equipment by cutting the insulation of the power supply lead of the unit and tapping into the lead. [. . . ] Never feed power to other equipment by cutting the insulation of the power supply lead of the unit and tapping into the lead. When replacing fuse, be sure to use only fuse of the rating prescribed on the fuse holder. Since a unique BPTL circuit is employed, never wire so the speaker leads are directly grounded or the left and right speaker leads are common. Speakers connected to this unit must be highpower types with minimum rating of 45 W and impedance of 4 to 8 ohms. Connecting speakers with output and/or impedance values other than those noted here may result in the speakers catching fire, emitting smoke or becoming damaged. When this product's source is switched ON, a control signal is output through the blue/white lead. When an external power amp is being used with this system, be sure not to connect the blue/white lead to the amp's power terminal. Likewise, do not connect the blue/white lead to the power terminal of the auto-antenna. To avoid short-circuiting, cover the disconnected lead with insulating tape. Especially, insulate the unused speaker leads without fail. Consult with your nearest dealer if installation requires the drilling of holes or other modifications of the vehicle. Install the unit where it does not get in the driver's way and cannot injure the passenger if there is a sudden stop, like an emergency stop. If installation angle exceeds 60° from horizontal, the unit might not give its optimum performance. Fit the bracket provided on the vehicle to the unit in the same way that it was fitted to the original car stereo. If connectors other than the one supplied with this product are used, there is the possibility that sounds may mute and memorized information could be erased. The semiconductor laser will be damaged if it overheats, so don't install the unit anywhere hot ­ for instance, near a heater outlet. To terminal always supplied with power regardless of ignition switch position. If you use a cellular telephone, connect it via the Audio Mute lead on the cellular telephone. If not, keep the Audio Mute lead free of any connections. Bracket (not included) In some cases, this may not be provided on the vehicle.
