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. Do as follows:
1. Detach the two pads from each other.
2. Attach the pad with the loops: peel off the protective sheet from the
adhesive side, and attach the pad to the desired location in the car.
When you peel off the protective sheet, do not touch the adhesive
side with a finger. Ensure that the surface where you attach the pad
is dry and free from dirt and dust.
