Product Description

Car-specific Hi-fi Soft mute with 84xxx cable

3G Drive & Talk Hifi Soft mute enables the use of the car speak-

ers for phone conversation. The Hi-fi Soft mute box is designed to

handle the line signal running from the radio to the amplifier.

Speaker-function: This is achieved by using the mutebox-relays to

disconnect the rear line signals and connect the front line signals

to the carkit. This way the radio sound is muted and the sound

from the carkit is sent through the cars front speakers. You will

achieve a perfect hands-free sound without interference from the

car radio.

For a complete cable-set two item numbers are needed. The 1st

item number includes the mutebox and the car-specific cable-set.

The 2nd item number is a carkit-specific adaptor-cable for adapting

the car-specific cable to the carkit.

Power supply of the carkit: All car-specific cable-sets have an inte-

grated carkit power-supply. In the car-specific cable-sets the con-

stant 12v and the ground wire are connected to the 16 way con-

nector. This connector is to be fitted to the 16 way connector on

the carkit adaptor. This way power-supply, of the carkit, is

achieved without cutting the cars wiring loom.

Mute function: The mute-wire is connected from the carkit to the

mutebox through the carkit adaptor. The mute-wire is also con-

nected to the radios mute input. This enables the use of the radios

built in mute function. If the radios mute input pin is unknown the

mute wire can be found in a yellow fly-wire fitted with a bullet

connector. Please note that not all radios are equipped with a

mute function.

Installation description

Car-specific Hi-fi Soft mute with 84xxx cable

Needed items:

A. Mutebox. P/N: MOH

B. Car-specific cable. P/N: 84xxx

C. Box adaptor. P/N: AA300

D. 3G Carkit adaptor. P/N: DAxxx

E. Carkit.

Note: The Mutebox

is always delivered with cables

Installation:

1. Remove the radio unit from the centre consol.

2. Insert the Car-specific cable

between the connector on the radio and

the connector on the cars wiring loom. If there, in the connector removed

from the radio, are inserted small plugs which pins has no connection to the

radio. Then these plugs has to be moved to the connector fitted into the radio.

These small plugs can be used for ex. CD-changer, navigation, Optic Most-bus,

Can-bus or Steering wheel controls.

3. Check ignition source in connector

. If some of the supported car models

have an ignition source in the connector on the car-specific cable

the blue

ignition wire is connected to this position. If none of the supported car models

have an ignition source available in the connector then the blue ignition wire

is connected to the constant 12v source with a bullet connector. If an ignition

source is needed for the chosen carkit an IGNIBOX item no. “I” can be inserted

to create an artificial ignition source or the blue ignition wire can be discon-

nected from the red constant 12v and manually connected to an ignition

source found elsewhere.

4. Connect the carkit adaptor

to the Box adaptor

by connecting the 16 pin connector on the 3G carkit adaptor

to the Box adaptor

. If the carkit adaptor

includes a 4 pin

connector this can be directly connected to the 4 pin connector on a Kram Aux cable for improved Music quality. Note: An Aux cable is included in some 84xxx cables.

5. Connect the carkit

to the carkit adaptor

6. Connect the mute wire. If a Mute input exists in the connector on the Car-specific cable the yellow mute wire is connected to this position when delivered. If no Mute input is

available in the connector then the yellow mute wire is found close to the male connector fitted with a bullet connector. It can then be manually connected to a mute input. Con-

necting the mute wire is an option but may be required in some cars to achieve a full mute of all speakers. Note: Not all cars are equipped with a mute input.

7. Test the carkit. When the carkit, adaptor cable and Car-specific cable is installed correctly it will redirect your call through the cars front speakers and mute remaining speakers.
