User manual PIONEER DEH-1550 INSTALLATION

[. . . ] 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. If the RCA pin jack on the unit will not be used, do not remove the caps attached to the end of the connector. 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. [. . . ] 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. Yellow Fuse holder Yellow/black With a 2 speaker system, connect to the 2 speakers in the front or the rear. Use this for connections when you have the separately available amplifier. Power amp (sold separately) To system control terminal of the power amp or Auto-antenna relay control terminal (max. 7 When using a Subwoofer without using a different amp (sold separately) 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. 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. Do not connect anything to these speaker leads. Because of the complexity of today's technically advanced vehicle wiring systems, we recommend that your DFS Alarm be installed ONLY by a professional Pioneer installer. To ensure full proper operation of DFS Alarm, Pioneer suggests using only White/Red wire, electronic sensors capable of providing a pulse width greater than 64 ms. The white/orange lead should be connected to the "unlock" lead for your vehicles door locking system, so that when you open the driver's door by your vehicle's remote control, your Pioneer DFS Alarm is deactivated. First, locate the two wires from the lock/unlock switch that operate the factory door lock solenoid for the driver's side. Using a meter, determine which lead is used to unlock the door; connect this to the white/orange lead of your Pioneer Car Stereo. In the DFS Alarm menu, select the door-lock system type according to your vehicle (grounding or nongrounding). If you have difficulty wiring this connection, please consult your nearest Installation specialist. If your vehicle is equipped with a central door lock but the glass or shock sensor is not connected, if the window is broken and the central door lock is released, this unit's DFS Alarm will not operate. Pioneer recommends that both a shock sensor and glass sensor be installed when you are using the "Remote Disarming" feature. The blue/brown lead will provide a continuous +12 V output while alarm is sounding and for 30 minutes after initial trigger, up to 5 consecutive triggers. This lead has a maximum current capability of 500 mA and can be used to trigger a relay to disable the starter. In order for the "DFS Alarm" to operate when a window is broken, connect this unit's White/Red (ALARM SENSOR) lead to glass sensor securely. [. . . ] 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. The semiconductor laser will be damaged if it overheats, so don't install the unit anywhere hot ­ for instance, near a heater outlet. [. . . ]
