User manual BLAUPUNKT MONTREAL RCM 169

[. . . ] During operation of the unit, the set's side wall may heat up considerably. Be sure to keep all wires away from hot parts of the housing. In some vehicles you will find a 20-pin connector pre-fitted in the dashboard's installation space. [. . . ] This connector must not be used for connecting the car radio! in vehicles manufactured by Audi and VW , the 8-pin positive/negative connector provided in the car must not be connected to a Blaupunkt radio directly!Otherwise the permanent +12 V line will be short-circuited to ground, leading to serious damage of the radio's internal circuitry (burn-out of printed conductor). In order to take advantage of the full car radio output and to avoid incorrect electrical connections with ISO plugs in the vehicle, it is advisable not to use the vehicle-specific positive/negative connection for this car radio. You can avoid making incorrect connections by using the vehiclespecific Blaupunkt adapter wiring. Due to the limited cross-section of the wiring in the vehicle, it is necessary to use the connection cable 7 607 884 093 in addition to the vehiclespecific Blaupunkt adapter wiring for the positive/negative connection. 4, 5 Positive connection Cut the permanent +12 volts line from the vehicle-specific Blaupunkt adapter wiring, join it with connection cable 7 607 884 093 and connect it directly to the positive terminal of the battery. Negative connection Do not connect the negative line to the negative terminal of the battery. Cut the negative line from the vehicle-specific Blaupunkt adapter wiring, join it with connection cable 7 607 884 093 and lay the negative line to a suitable ground, such as a chassis screw, the chassis itself or corresponding grounds (do not roll up the wiring). Lay the negative line to a suitable ground, such as a chassis screw or the chassis itself. then strip the insulation and attach a cable lug (solder if necessary). Remove the paint of the ground contact surface and treat with graphite grease (important for a good ground connection). Brown / ground When connecting the positive line to terminal 15 of the fuse box (+12 V via ignition) behind the fuse, it will be possible to turn the system on and off via the ignition. Also, the unit will automatically switch off after one hour of playback time to avoid that the battery goes flat. This hour logic will not be activated when connecting the permanent +12 V line (terminal 30). Do not connect the vehicle's positive line !5 mm2 cross section to the battery (do not route close to vehicle harnesses). Connect the fuse box to protect the positive line and hook up to the positive terminal of the battery. [. . . ] Connect the fuse box to protect the positive line and hook up to the positive terminal of the battery. If necessary, drill a hole into the splash wall and use a cable duct as required. The control wire is the switched positive output for external pieces of equipment such as a power antenna, maximum load < 150 mA. [. . . ]
