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 cables are routed as far away as possible from the vehicle’s electronic systems
(refer to WARNINGS)*. Also, ensure that cables are not subjected to undue mechanical
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
Ignition Sense IGNS
The ignition sense feature prevents your car kit from draining the car battery by execut-
ing an auto power off in 20 seconds after the ignition key has been turned off. The blue
wire of the power cable is used for the ignition sense feature. The use of ignition sense is
recommended to prevent accidental draining of the car’s battery. The wire is connected
via a 1 A fuse to a 12/24 volt potential that is controlled by the ignition key. Do not con-
nect it directly to the high voltage sections of the ignition circuit.
Car Radio Muting CRM
The car kit offers a feature that can mute the car radio automatically during a conversa-
tion. This feature is convenient and provides for safer handsfree operation. The car radio
muting feature is based on a grounded line, so it means that in standby, the yellow wire
(XCRM) is not grounded and car radio works normally, but during a call, line is grounded
and car radio is muted. Note that an auxiliary relay or muting unit must be used when
the car radio doesn’t have a mute feature available.
When a relay is used, connect of series with the car radio main supply. A 200 mA fuse
