Operation Mode FLASH

In this case, the switch has to be in the position FLASH and the power connector FLASH must be connected to the service battery cable from FLA-7. In addition, the power supply at the power connector JBD-2 must be +13.5 V. Figure 14. Principle old Flash concept Technical Documentation JBD-2 User Guide

Power Distribution

The main supply for mobile phone is obtained from the vehicle battery, the supply voltage may vary between 11,8 and 16 volts. Both the positive voltage and the grounding are taken directly from the battery, unless the vehicle has other main voltage than +12 V. This minimizes the risk of disturbances from or to the telephone as well as guarantees loss-free power The connections to the battery should be carried out with care. Both the negative and positive leads have 3A fuses, which must always...

Installation

Technical Documentation Installation instructions The handsfree microphone can be installed on the driver's sunvisor or the A pillar. Ensure the microphone is as close to the driver's mouth as possible, and attached to a surface that is mechanically quiet. The microphone should be mounted at least 3 ft 1 m away from the handsfree unit speaker to avoid acoustic feedback. The loudspeaker isn't so sensitive for vibrations, thus it can be located more freely. The main idea is to optimize two...

System Cable SCM and Vehicle Installation Cable DKS

The system cable connects the phone to the vehicle supply and accessories. The power wires red and black - shall be routed to the battery itself alternatively to the main distribution point of the vehicles fuse box both and - must be fuse protected 3 A . The blue ignition sense IGNS wire is connected to 12 V voltage controlled by the vehicle's ignition key via 1A fuse. The ignition sense can utilize voltages up to 24 V, see section Ignition Sense The yellow wire is used for car radio muting...

Handsfree Microphone HFM and Handsfree Speaker HFS

The safest and easiest way to have call while driving is use the handsfree option. The system consist of two components, the microphone HFM-15 and loudspeaker HFS-10. The microphone needs to be as close to the drivers mouth as possible and attached to a surface that is mechanically quiet. The microphone connects to the system cable MIC molex connector but avoids the fan output area in order to maintain the quality of audio. The loudspeaker should be mounted at least 3 ft 1 m away from the...

Testing

Once installed, the equipment should be tested to ensure that it is operating satisfactorily and that the position of the units does not impair on the driver's ability to control and operate the vehicle in any way. Use the phone to make a call when the vehicle is parked with the engine running. During the call, switch off the engine. Ensure that the phone is operational with the engine running and with the engine switched off. For operating information refer to the 'User Guide' supplied with...

Remote Interface

Remote Interface allows all manual adjustments to be controlled. The results of the VDA measurements AMC amp CRM and the result of detecting the DC voltage level in the HFMIC path, are available as output on the interface. Use a PC to control the JBD-2 from the lEC-to-Parallel interface. For example ICS 4863 - GPIB Parallel Interface To activate the remote control, the remote line REMOTE_EN has to be set to logical level high 5V . The different audio paths can be selected with the three BCD...

Power Antenna Control ANTC

The orange wire of the system cable ANTC 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 disappears. The maximum output current is 180 mA, therefore for example motorized antenna must be controlled via a relay, see picture below.

Ignition Sense IGNS

The ignition sense feature prevents the transceiver from draining the car battery by executing an auto power off 45 sec.- 24 houres after the ignition key has been turned off unless the Auto Power Off feature is deactivated . 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 volt potential that is controlled by the ignition key. Do not...

Technical Overview

Internal Connection Signal System

The mobile is built around the DCT-3 core originally designed for a handportable phone to operate in the GSM system. This is possible with a modest extension to the hardware as some provisions for use in a mobile are already included in the original core design. Some extensions to the original design has been necessary to be able to operate in an automotive environment, to include built-in handsfree operation and to use an active handset instead of the UI flex board of the handheld. The purpose...
