After SalesTechnical DocumentationInstallation InstructionsPage 12Original 18/96InstallationThere are some important aspects that require special attention in positioningcar kit accessories.The positioning of the phone holder is the most important factor when trying toachieve the most comfortable position for the user. The location of the holdershould be selected so that the visibility of the phone’s display is good under alllighting conditions, but not so that the driver’s attention is easily distracted. Theholder should be located so that the driver can easily reach the keypad. Underno circumstances should the holder prevent the driver from controlling or oper-ating the vehicle in any way or observing traffic.The fixed mobile charger can be installed in a hidden location, since there is noneed to disconnect cables during normal operation. Ensure the location doesnot subject the unit and cables to moisture or mechanical pressure. Also re-member clean the mounting tape location properly before installing.The handsfree microphone can be installed on the driver’s sunvisor or theA–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 bemounted at least 3 ft/1 m away from the handsfree unit speaker to avoid acous-tic feedback. See separate microphone installation guide.Ensure cables are routed as far away as possible from the vehicle’s electronicsystems (refer to WARNINGS). Also ensure cables are not subjected to unduemechanical stress e.g. under seats or against sharp edges. The external anten-na adapter should always be connected to the antenna via a non–radiatingcable (e.g. coax).The most important component of the installation is the antenna. The locationof the antenna as well the quality of the antenna and its installation have a con-siderable influence to the overall performance of the whole system. Therefore itis necessary to emphasize some aspects, which too often have caused unnec-essary service work.The best place for the antenna is the rooftop. The overall performance of arooftop antenna is clearly superior to any other antenna type or location. TheAntenna shall be mounted in a position such that no part of human body willnormally rest too close to any part of the antenna unless there is a an intervent-ing metallic screen, for example, the metallic roof.• highest place in the car• proper ground place• omnidirectional radiation pattern• minimum risk for disturbances• user safety
