Installation
To mount the remote control button, use the hook and loop tape
provided. First detach the two parts of the pads from each other. Attach
the pad with the loops first: peel off the protective sheet from the
adhesive side (A) and attach the pad to the desired location in your car
(B). Make sure that the surface where you intend to attach the pad is
dry and free from dirt and dust.
Attach the pad with the hooks next: peel off the protective sheet from
the adhesive side (C) and attach the pad to the underside of the remote
control button.
Press the remote control button (D) firmly onto the loop pad mounted
in the car.
Loudspeaker
To ensure good acoustic quality, mount the loudspeaker so that it is
pointed in the user's direction. We recommend that you mount the
loudspeaker a minimum distance of 3.28 feet away from the
microphone to avoid feedback.
The Advanced Car Kit also supports connection to a compatible car radio
system. If yo wish to use the car radio installed in your vehicle with the
Advanced Car Kit for audio output, ask your service technician for
professional advice.
Connect the loudspeaker or a compatible car radio system to the
"SPEAKER" output.
Microphone
Careful selection of the mounting location of the microphone can
increase the quality of voice transmission.
Mount the microphone approx. 11.8 inches from the user's head, and
position it so that it points towards the user's mouth. Experience has
shown that the best locations are near the rearview mirror or the sun
visor. We recommend that you keep the microphone a minimum distance
of 3.28 feet away from the Advanced Car Kit phone loudspeaker to
avoid feedback.
