Handset HSU-1T (not supplied)
The handset HSU-1T offers more privacy during a call. During a one-way call the PTT key
must be used. It connects to the DATA/HANDSET socket of HFU-2T or to the DTC-1
adapter cable HANDSET socket (please refer to DTC-1). For more information, please
refer to the user guide for the handset.
Installation
For an example of installation locations, please see the cover.
Note: Ensure that the battery of the vehicle is disconnected before you start the
installation or start making changes to the installations, and that it remains disconnected
during the installation procedure.
The HFU-2T and the different parts are connected as mentioned in the ”Component Parts”
section.
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 radio's display is easily visible
and that the driver’s attention is not distracted. The location of the holder should allow the
driver to easily reach the keypad. Under no circumstances should the holder in any way
prevent the driver from controlling or operating the vehicle.
The HF microphone should be installed according to the directions in the separate
microphone installation guide. Ensure that 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.
Ensure that the cables are routed as far away as possible from the vehicle’s electronic
systems. This is to prevent interference. Also, ensure that the cables are not subjected to
undue mechanical stress e.g. under seats or against sharp edges.
