PAMS CARK–91 Technical Documentation Unpacking Carefully unpack the equipment and ensure that the following items are present.
PAMS CARK–91 Technical Documentation Component Parts Advanced Active Holder MCC–1 The holder allows the phone to be firmly located in a convenient position. The holder is attached to the vehicle’s interior using the swivel mount HHS–9. The mounting must be secured with a screw (included with HHS–9). The screw recess can then be covered with the NOKIA logo plate. Advanced HF Unit HFU–2 The handsfree unit enables the phone to operate in handsfree mode.
PAMS Technical Documentation CARK–91 Power Cable PCH–4J The power cable connects the standard handsfree unit HFU–2 to the vehicle’s power supply. The red wire must be connected to the + voltage on the vehicle’s power supply via the supplied fused connector. The black wire must be attached to a good negative GND connection. The blue ignition sense (IGNS) wire is connected to +12 V voltage controlled by the vehicle’s ignition key via the supplied fused connector. See section ”Ignition Sense”.
PAMS CARK–91 Technical Documentation Installation There are some important aspects that require special attention in positioning car kit accessories. The positioning of the phone holder is the most important factor when trying to achieve the most comfortable position for the user. The location of the holder should be selected so that the visibility of the phone’s display is good under all lighting conditions, but not so that the driver’s attention is easily distracted.
PAMS CARK–91 Technical Documentation Ignition Sense IGNS The ignition sense feature prevents your car kit from draining the car battery by executing an auto power off in 20 seconds after the ignition key has been turned off. The blue wire of the power cable is used for the ignition sense feature. The use of ignition sense is recommended to prevent accidental draining of the car’s battery. The wire is connected via a 1 A fuse to a 12/24 volt potential that is controlled by the ignition key.
PAMS CARK–91 Technical Documentation Antenna Motor Control AMC The antenna motor control offers a feature, green wire of the system cable (AMC), that may be used to control different devices on and off. The voltage in this output is +12 V whenever the phone is on. If the phone is turned off, the voltage disappeares. The maximum output current is 200 mA, therefore for example motorized antenna must be controlled via a relay, see picture below. Bosch P/N 0–332–204–150 12 V, 30 A. SPDT 87A 12 V d.c.
