When you install the hands-free unit, ensure that the cables for the 
microphone and loudspeaker reach the places where you intend to 
mount these parts.
Do not mount the hands-free unit inside a metal housing or on a metal 
surface because this will impair the Bluetooth connection between the 
hands-free unit and the Bluetooth device that is connected to the car 
kit. For an optimal connection, ensure that the distance between the 
hands-free unit and a metal surface is over 4 mm (0.16 inch).
To mount the hands-free unit, use the hook and loop tape pads supplied 
with the car kit in the same way as with the input device (see the figures 
in Input device starting from p. 24). Detach the two pads from each 
other. Attach the pad with the loops first: peel off the protective sheet 
from the adhesive side, and attach the pad to the desired location in the 
car. Ensure that the surface where you attach the pad is dry and free 
from dirt and dust.
To attach the pad with the hooks, peel off the protective sheet from the 
adhesive side, and attach the pad to the underside of the 
hands-free unit.
Press the hands-free unit firmly onto the loop pad, and check that the 
hands-free unit stays securely in place.
