IMPORTANT
Special attention should be given to locating a
good
vehicle
ground.
performance can only be achieved with a ground
connection having a very low resistance. The
vehicle frame makes the best ground, but body
Some vehicle audio systems are equipped with an external
mute wire, which when grounded causes the audio system to
be muted. Connect the orange wire from the power cable to
the mute line of the audio system. The entertainment mute
feature causes the orange wire to be grounded (max 100mA)
whilst a call is in progress, thus muting the audio system.
The AUX Alert feature can be used to trigger an external
device to alert the user that there is an incoming call whilst
they are away from the vehicle. To activate this feature, cut
and strip the Yellow wire and connect it to a relay.
NOTE: The AUX Alert requires the use of an external relay
(not supplied) to connect it to the horn or lights, this feature
sources 100mA.
3.6 MICROPHONE INSTALLATION
The installation brackets provided with the microphone
offer the simplest and most effective mounting method(s).
Finally, connect he microphones connector to the DHFA
adapter box connector and route to the sun visor or pillar.
IMPORTANT
The microphone should never be installed near
the side window, or in a location where the road
and ambient background noise would be
excessively high (greater than 85 dB SPL). Also
the microphone should be located at least 0.5m
away from the external speaker, to reduce the
3.7 EXTERNAL SPEAKER INSTALLATION
The external speaker should only be mounted using the
bracket supplied. The speaker location should not interfere
with the vehicle operation, and its cable plug must be able
to reach the external speaker socket on the power cable. The
ideal mounting place is on the passenger side of the console,
in front of any sound absorbing barriers. The speaker should
always be positioned as far away as possible from the
microphone (at least 0.5m) to prevent any feedback
problems.
Step 1.
Using the speaker bracket as a template, drill two

holes and mount at the desired location, using the
two self tapping screws provided.
Step 2.
Connect to the mating connector on the DHFA
adapter box.
IMPORTANT
It is recommended not to route the rf cable near
to the power, microphone or speaker cables. As
audible noise may be induced into them, whilst
3.8 EXTERNAL ANTENNA INSTALLATION
The centre of the vehicle roof is considered to be the best
location for mounting the antenna. Before drilling any
holes, ensure that:-
•
The antenna cable can be routed to the StarTAC Cradle
assembly with ease.
•
There is no electrical interference at the chosen
location - use a temporary magnet mount antenna.
Note that two metal items rubbing against each other such
as seat springs, boot and bonnet lids, exhaust pipes and
similar items close to the antenna can cause severe radio
interference.
An optional 'through-the-glass' type antenna can be
mounted on the rear window of the vehicle. This type of
antenna should be mounted as high as is possible on the
window. Care should be taken to ensure that the inductive
button on the mounting foot does not cross any of the rear
window demister elements. Refer to the manufacturer's
specific installation instructions.
For a normal installation, proceed as follows. If the antenna
coaxial cable is already terminated with a mini UHF
connector, proceed to Step 8.
Step 1.
Slip the ferrule and the collar onto the antenna
coaxial connector as shown in Figure 5.
Step 2.
Strip the cable to the dimensions shown in Figure 6.
Step 3.
Insert the stripped cable into the connector body
until the centre conductor is exposed and the
dielectric bottoms inside the connector body - see
Figure 5.
Step 4.
Crimp the centre contact using a suitable
crimping tool.
