Installation
For an example of installation locations, please see the CARK132 cover page.
Note: Ensure that the battery of the vehicle is disconnected before you start the
installation or making changes to the installations, and that it remains disconnected
during the installation procedure.
The HFU-5 and the different parts are connected as mentioned in the section ”Com-
ponent Parts”.
There are some important aspects that require special attention in positioning car kit
accessories.
The location of the holder should be selected so that the holder is always in an up-
ward position (see Fig.2) and that the visibility of phone’s display is good and the
driver’s attention is not distracted. The location of holder should allow the driver to
easily reach the keypad. Under no circumstances should the holder prevent the driv-
er from controlling or operating the vehicle in any way.
The HF microphone should be installed according to the directions in the separate
microphone installation guide. Ensure the microphone is as close to the driver’s
mouth as possible, and attached to a surface that is mechanically quiet. The micro-
phone should be mounted at least 3 ft/1 m away from the handsfree unit speaker to
avoid acoustic feedback.
Ensure the cables are routed as far away as possible from the vehicle’s electronic
systems. This is to prevent interference. Also, ensure that cables are not subjected
to undue mechanical stress e.g. under seats or against sharp edges.
