External Mobile Antenna (not supplied)

The cellular phone is designed to operate with a high quality external antenna. However,
due to many different types of antennas being available, an antenna is NOT included as
part of this kit. Please consult the dealer to find out which is the most suitable antenna
type for your installation.

Installation

There are some important aspects that require special attention in positioning car kit
accessories.
The positioning of the phone holder is the most important factor when trying to achieve
the most comfortable position for the user. The location of the holder should be selected
so that the visibility of the phone's display is good under all lighting conditions, but not
so that the driver's attention is easily distracted. The holder should be located so that the
driver can easily reach the keypad. Under no circumstances should the holder prevent the
driver from controlling or operating the vehicle in any way or observing traffic.
The HF microphone should be installed according to the directions in the separate micro-
phone installation guide. Ensure the microphone is as close to the driver's mouth as pos-
sible, 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 feed-
back.
Ensure that cables are routed as far away as possible from the vehicle's electronic sys-
tems (refer to WARNINGS)*. Also, ensure that cables are not subjected to undue mechan-
ical stress (e.g. under seats or against sharp edges.
* To prevent disturbance, cables should be routed as far away from the interference
source as possible
